warnings and precautions for use.
COMIRNATY (orange cap, must dilute)
Vials have an orange cap and after
dilution contain ten doses of 0.2 mL of vaccine. In order
to extract ten doses from a single vial, low dead-volume syringes and/or needles should be
used. The low dead-volume syringe and needle combination should have a dead volume of no
more than 35 microlitres. If standard syringes and needles are used, there may not be sufficient
volume to extract a tenth dose from a single vial. Irrespective of the type of syringe and needle:
• Each dose must contain 0.2 mL of vaccine.
• If the amount of vaccine remaining in the vial cannot provide a full dose of 0.2 mL, discard
the vial and any excess volume.
• Do not pool excess vaccine from multiple vials.

General recommendations
Hypersensitivity and anaphylaxis
Events of anaphylaxis have been reported. Appropriate medical treatment and supervision
should always be readily available in case of an anaphylactic reaction following the
administration of COMIRNATY.
Released
The individual should be kept under close observation for at least 15 minutes following
vaccination. A second dose of COMIRNATY should not be given to those who have
experienced anaphylaxis to the first dose of COMIRNATY.
Myocarditis and pericarditis
Very rare cases of myocarditis and pericarditis have been observed following vaccination with
COMIRNATY. These cases have primarily occurred within 14 days following vaccination,
more often after the second vaccination, and more often in younger men. Available data
under the Official Information Act 1982
suggest that the course of myocarditis and pericarditis following vaccination is not different
from myocarditis or pericarditis in general.
Healthcare professionals should be alert to the signs and symptoms of myocarditis and
pericarditis. Vaccinees should be instructed to seek immediate medical attention if they
develop symptoms indicative of myocarditis or pericarditis such as (acute and persisting) chest
pain, shortness of breath, or palpitations following vaccination. Healthcare professionals
should consult guidance and/or specialists to diagnose and treat this condition.
Stress-related responses
Some individuals may have stress-related responses associated with the process of vaccination
itself. Stress-related responses are temporary and resolve on their own. They may include
dizziness, fainting, palpitations, increases in heart rate, alterations in blood pressure, feeling
short of breath, tingling sensations, sweating and/or anxiety. Individuals should be advised to
bring symptoms to the attention of the vaccination provider for evaluation and precautions
should be in place to avoid injury from fainting.
Concurrent illness
Vaccination should be postponed in individuals suffering from acute severe febrile illness or
acute infection. The presence of a minor infection and/or low grade fever should not delay
vaccination.
Thrombocytopenia and coagulation disorders
As with other intramuscular injections, COMIRNATY should be given with caution in
individuals receiving anticoagulant ther apy or those with thrombocytopenia or any coagulation
disorder (such as haemophilia) bec ause bleeding or bruising may occur following an
intramuscular administration in these individuals.
Immunocompromised individuals
The efficacy, safety and immunogenicity of COMIRNATY has not been assessed in
immunocompromised individuals, including those receiving immunosuppressant therapy. The
efficacy of COMIRNATY may be lower in immunosuppressed individuals.

Duration of protection
The duration of protection afforded by COMIRNATY is unknown as it is still being determined
by ongoing clinical trials.
Limitations of vaccine effectiveness
As with any vaccine, vaccination with COMIRNATY may not protect all vaccine recipients.
Released
Individuals may not be fully protected until 7 days after their second dose of COMIRNATY.
Use in the elderly
Clinical studies of COMIRNATY include participants 65 years of age and older and their data
contributes to the overall assessment of safety and efficacy. See Section 5.1 Pharmacodynamic
properties, Clinical trials, Efficacy against COVID-19.
Paediatric use under the Official Information Act 1982
The safety and efficacy of COMIRNATY in children aged less than 5 years of age have not
yet been established.
Effects on laboratory tests
No data available.
4.5 Interactions with other medicines and other forms of interactions
No interaction studies have been performed.
Concomitant administration of COMIRNATY with other vaccines has not been studied.
4.6 Fertility, pregnancy and lactation
Fertility
In a combined fertility and developmental toxicity study, female rats were intramuscularly
administered COMIRNATY prior to mating and during gestation (4 full human doses of
30 micrograms each, spanning between pre-mating day 21 and gestation day 20). SARS-CoV-
2 neutralising antibodies were present in maternal animals from prior to mating to the end of
the study on postnatal day 21 as well as in fetuses and offspring. There were no vaccine related
effects on female fertility and pregnancy rate.
Pregnancy
There is limited experience with use of COMIRNATY in pregnant women. Animal studies do
not indicate direct or indirect harmful effects with respect to pregnancy, embryo/fetal
development, parturition or post-natal development (see Section 4.6 Fertility, pregnancy and
lactation, Fertility). Administration of COMIRNATY in pregnancy should only be considered
when the potential benefits outweigh any potential risks for the mother and fetus.
Lactation
It is unknown whether tozinameran is excreted in human milk. A combined fertility and
developmental toxicity study in rats did not show harmful effects on offspring development
before weaning (see Section 4.6 Fertility, pregnancy and lactation, Fertility).

Summary of safety profile
The safety of COMIRNATY was evaluated in participants 5 years of age and older in 3 clinical
studies that included 24,675 participants (comprised of 22,026 participants 16 years of age and
older, 1,131 adolescents 12 to 15 years of age and 1,518 children 5 to 11 years of age) that have
received at least one dose of COMIRNATY.
under the Official Information Act 1982
Additionally, 306 existing Phase 3 participants at 18 to 55 years of age received a booster dose
(third dose) of COMIRNATY approximately 6 months after the second dose. The overall
safety profile for the booster dose (third dose) was similar to that seen after 2 doses.
Participants 16 years of age and older – after 2 doses
In Study C4591001, a total of 22,026 participants 16 years of age or older received at least 1
dose of COMIRNATY 30 micrograms and a total of 22,021 participants 16 years of age or
older received placebo (including 138 and 145 adolescents 16 and 17 years of age in the
COMIRNATY and placebo groups, respectively). A total of 20,519 participants 16 years of
age or older received 2 doses of COMIRNATY.
At the time of the analysis of Study C4591001 with a data cut-off of 13 March 2021 for the
placebo-controlled blinded follow-up period up to the participants’ unblinding dates, a total of
25,651 (58.2%) participants (13,031 COMIRNATY and 12,620 placebo) 16 years of age and
older were followed up for ≥4 months after the second dose. This included a total of 15,111
(7,704 COMIRNATY and 7,407 placebo) participants 16 to 55 years of age and a total of
10,540 (5,327 COMIRNATY and 5,213 placebo) participants 56 years and older.
The most frequent adverse reactions in participants 16 years of age and older that received 2
doses were injection site pain (>80%), fatigue (>60%), headache (>50%), myalgia (>40%),
chills (>30%), arthralgia (>20%), pyrexia and injection site swelling (>10%) and were usually
mild or moderate in intensity and resolved within a few days after vaccination. A slightly lower
frequency of reactogenicity events was associated with greater age.
The safety profile in 545 subjects receiving COMIRNATY, that were seropositive for SARS-
CoV-2 at baseline, was similar to that seen in the general population.
Study C4591001 also included 200 participants with confirmed stable human
immunodeficiency virus (HIV) infection. The safety profile of the participants receiving
COMIRNATY (n=100) in the individuals with stable HIV infection was similar to that seen in
the general population.
Adolescents 12 through 15 years of age – after 2 doses
In an analysis of Study C4591001, 2,260 adolescents (1,131 COMIRNATY 30 micrograms;
1,129 placebo) were 12 through 15 years of age. Of these, 1,308 adolescents

Children 5 to 11 years of age – after 2 doses
In an analysis of Study C4591007 Phase 2/3, 2,268 children (1,518 COMIRNATY
10 micrograms; 750 placebo) were 5 to 11 years of age. Of these, 2,158 (95.1%)
(1,444 COMIRNATY 10 micrograms and 714 placebo) children have been followed for at
least 2 months after the second dose. The safety evaluation in Study C4591007 is ongoing.
The most frequent adverse reactions in children 5 to 11 years of age that received 2 doses
included injection site pain (>80%), fatigue (>50%), headache (>30%), injection site redness
under the Official Information Act 1982
and swelling (>20%), myalgia and chills (>10%).
Participants 18 years of age and older – after booster dose
A subset from Study C4591001 Phase 2/3 participants of 306 adults 18 to 55 years of age who
completed the original COMIRNATY 2-dose course, received a booster dose (third dose) of
COMIRNATY approximately 6 months (range of 4.8 to 8.0 months) after receiving Dose 2.
The most frequent adverse reactions in participants 18 to 55 years of age were injection site
pain (>80%), fatigue (>60%), headache (>40%), myalgia (>30%), chills and arthralgia (>20%).

5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: vaccines, other viral vaccines, ATC code: J07BX03.
Mechanism of action
The nucleoside-modified messenger RNA in COMIRNATY is formulated in lipid
nanoparticles, which enable delivery of the non-replicating RNA into host cells to direct
transient expression of the SARS-CoV-2 spike (S) antigen. The mRNA codes for membrane-
anchored, full-length S with two point mutations within the central helix. Mutation of these
two amino acids to proline locks S in an antigenically preferred prefusion conformation.
COMIRNATY elicits both neutralising antibody and cellular immune responses to the antigen,
which may contribute to protection against COVID-19.
Clinical efficacy and safety
Efficacy
Study C4591001 is a multicentre, multinational, Phase 1/2/3 randomised, placebo-controlled,
observer-blind dose-finding, vaccine candidate selection and efficacy study in participants 12
years of age and older. Randomisation was stratified by age: 12 to 15 years of age, 16 to 55
years of age, or 56 years of age and older, with a minimum of 40% of participants in the ≥56-
year stratum. The study excluded participants who were immunocompromised and those who
had previous clinical or microbiological diagnosis of COVID-19. Participants with pre-existing
stable disease, defined as disease not requiring significant change in therapy or hospitalisation
for worsening disease during the 6 weeks before enrolment, were included as were participants
with known stable infection with HIV, hepatitis C virus (HCV) or hepatitis B virus (HBV).
Efficacy in participants 16 years of age and older – after 2 doses
In the Phase 2/3 portion of Study C4591001, based on data accrued through
14 November 2020, approximately 44,000 participants were randomised equally and were to
Version: pfdcocii21221
Supersedes: pfdcocii11221
Page 9 of 26
receive 2 doses of COMIRNATY or placebo. The efficacy analyses included participants that
received their second vaccination within 19 to 42 days after their first vaccination. The majority
(93.1%) of vaccine recipients received the second dose 19 days to 23 days after Dose 1.
Participants are planned to be followed for up to 24 months after Dose 2, for assessments of
safety and efficacy against COVID-19. In the clinical study, participants were required to
observe a minimum interval of 14 days before and after administration of an influenza vaccine
in order to receive either placebo or COMIRNATY. In the clinical study, participants were
Released
required to observe a minimum interval of 60 days before or after receipt of blood/plasma
products or immunoglobulins through to conclusion of the study in order to receive either
placebo or COMIRNATY.
The population for the analysis of the primary efficacy endpoint included 36,621 participants
12 years of age and older (18,242 in the COMIRNATY group and 18,379 in the placebo group)
who did not have evidence of prior infection with SARS-CoV-2 through 7 days after the second
dose. In addition, 134 participants were between the ages of 16 to 17 years of age (66 in the
under the Official Information Act 1982
COMIRNATY group and 68 in the placebo group) and 1616 participants 75 years of age and
older (804 in the COMIRNATY group and 812 in the placebo group).
At the time of the primary efficacy analysis, participants had been followed for symptomatic
COVID-19 for in total 2,214 person-years for the COMIRNATY group and in total 2,222
person-years for the placebo group.
There were no meaningful clinical differences in overall vaccine efficacy in participants who
were at risk of severe COVID-19 including those with 1 or more comorbidities that increase
the risk of severe COVID-19 (e.g. asthma, body mass index (BMI) ≥30 kg/m2, chronic
pulmonary disease, diabetes mellitus, hypertension).
COMIRNATY efficacy information is presented in Table 4.

In Study C4591001 an analysis of SARS-CoV-2 neutralising titres in a randomly selected

subset of participants was performed to demonstrate non-inferior immune responses (within
1.5-fold) comparing adolescents 12 to 15 years of age to participants 16 to 25 years of age who
had no serological or virological evidence of past SARS-CoV-2 infection. The immune
1982
response to COMIRNATY in adolescents 12 to 15 years of age (n = 190) was non-inferior to
the immune response in participants 16 to 25 years of age (n = 170), based on results for SARS-
CoV-2 neutralising titres at 1 month after Dose 2. The geometric mean titres (GMT) ratio of
the adolescents 12 to 15 years of age group to the participants 16 to 25 years of age group was
1.76, with a 2-sided 95% CI of 1.47 to 2.10, meeting the 1.5-fold non-inferiority criterion (the
lower bound of the 2-sided 95% CI for the geometric mean ratio [GMR] >0.67), which
indicates a statistically greater response in the adolescents 12 to 15 years of age than that of
participants 16 to 25 years of age.

analyses of NT50 1 month after the booster dose compared to 1 month after the primary series
in individuals 18 to 55 years of age who had no serological or virological evidence of past
SARS-CoV-2 infection up to 1 month after the booster vaccination demonstrated

General recommendations
Hypersensitivity and anaphylaxis
Events of anaphylaxis have been reported. Appropriate medical treatment and supervision
should always be readily available in case of an anaphylactic reaction following the
administration of COMIRNATY.
Released
The individual should be kept under close observation for at least 15 minutes following
vaccination. A second dose of COMIRNATY should not be given to those who have
experienced anaphylaxis to the first dose of COMIRNATY.
Myocarditis and pericarditis
Very rare cases of myocarditis and pericarditis have been observed following vaccination with
COMIRNATY. These cases have primarily occurred within 14 days following vaccination,
more often after the second vaccination, and more often in younger men. Available data
under
suggest that the course of myocarditis and pericarditis following vaccination is not different
from myocarditis or pericarditis in general.
Healthcare professionals should be alert to the signs and symptoms of myocarditis and
pericarditis. Vaccinees should be instructed to seek immediate medical attention if they
the
develop symptoms indicative of myocarditis or pericarditis such as (acute and persisting) chest
pain, shortness of breath, or palpitations following vaccination. Healthcare professionals
Official
should consult guidance and/or specialists to diagnose and treat this condition.
Stress-related responses
Some individuals may have stress-related responses associated with the process of vaccination
itself. Stress-related responses are temporary and resolve on their own. They may include
dizziness, fainting, palpitations, increases in heart rate, alterations in blood pressure, feeling
Information
short of breath, tingling sensations, sweating and/or anxiety. Individuals should be advised to
bring symptoms to the attention of the vaccination provider for evaluation and precautions
should be in place to avoid injury from fainting.
Concurrent illness
Vaccination should be postponed in individuals suffering from acute severe febrile illness or
acute infection. The presence of a minor infection and/or low grade fever should not delay
vaccination.
Act
Thrombocytopenia and coagulation disorders
As with other intramuscular injections, COMIRNATY should be given with caution in
1982
individuals receiving anticoagulant ther apy or those with thrombocytopenia or any coagulation
disorder (such as haemophilia) bec ause bleeding or bruising may occur following an
intramuscular administration in these individuals.
Immunocompromised individuals
The efficacy, safety and immunogenicity of COMIRNATY has not been assessed in
immunocompromised individuals, including those receiving immunosuppressant therapy. The
efficacy of COMIRNATY may be lower in immunosuppressed individuals.

Duration of protection
The duration of protection afforded by COMIRNATY is unknown as it is still being determined
by ongoing clinical trials.
Limitations of vaccine effectiveness
As with any vaccine, vaccination with COMIRNATY may not protect all vaccine recipients.
Released
Individuals may not be fully protected until 7 days after their second dose of COMIRNATY.
Use in the elderly
Clinical studies of COMIRNATY include participants 65 years of age and older and their data
contributes to the overall assessment of safety and efficacy. See Section 5.1 Pharmacodynamic
properties, Clinical trials, Efficacy against COVID-19.

4.6 Fertility, pregnancy and lactation
Fertility
In a combined fertility and developmental toxicity study, female rats were intramuscularly
administered COMIRNATY prior to mating and during gestation (4 full human doses of
30 micrograms each, spanning between pre-mating day 21 and gestation day 20). SARS-CoV-
2 neutralising antibodies were present in maternal animals from prior to mating to the end of
the study on postnatal day 21 as well as in fetuses and offspring. There were no vaccine related
Act
effects on female fertility and pregnancy rate.
Pregnancy
1982
There is limited experience with use of COMIRNATY in pregnant women. Animal studies do
not indicate direct or indirect harmful effects with respect to pregnancy, embryo/fetal
development, parturition or post-natal development (see Section 4.6 Fertility, pregnancy and
lactation, Fertility). Administration of COMIRNATY in pregnancy should only be considered
when the potential benefits outweigh any potential risks for the mother and fetus.
Lactation
It is unknown whether tozinameran is excreted in human milk. A combined fertility and
developmental toxicity study in rats did not show harmful effects on offspring development
before weaning (see Section 4.6 Fertility, pregnancy and lactation, Fertility).

5. PHARMACOLOGICAL PROPERTIES
Information
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: vaccines, other viral vaccines, ATC code: J07BX03.
Mechanism of action
The nucleoside-modified messenger RNA in COMIRNATY is formulated in lipid
nanoparticles, which enable delivery of the non-replicating RNA into host cells to direct
transient expression of the SARS-CoV-2 spike (S) antigen. The mRNA codes for membrane-
anchored, full-length S with two point mutations within the central helix. Mutation of these
Act
two amino acids to proline locks S in an antigenically preferred prefusion conformation.
COMIRNATY elicits both neutralising antibody and cellular immune responses to the antigen,
which may contribute to protection against COVID-19.

Clinical efficacy and safety
Efficacy
Study C4591001 is a multicentre, multinational, Phase 1/2/3 randomised, placebo-controlled,
observer-blind dose-finding, vaccine candidate selection and efficacy study in participants 12
years of age and older. Randomisation was stratified by age: 12 to 15 years of age, 16 to 55
years of age, or 56 years of age and older, with a minimum of 40% of participants in the ≥56-
year stratum. The study excluded participants who were immunocompromised and those who
had previous clinical or microbiological diagnosis of COVID-19. Participants with pre-existing

stable disease, defined as disease not requiring significant change in therapy or hospitalisation
for worsening disease during the 6 weeks before enrolment, were included as were participants
with known stable infection with HIV, hepatitis C virus (HCV) or hepatitis B virus (HBV).
Efficacy in participants 16 years of age and older – after 2 doses
In the Phase 2/3 portion of Study C4591001, based on data accrued through
14 November 2020, approximately 44,000 participants were randomised equally and were to
Released
receive 2 doses of COMIRNATY or placebo. The efficacy analyses included participants that
received their second vaccination within 19 to 42 days after their first vaccination. The majority
(93.1%) of vaccine recipients received the second dose 19 days to 23 days after Dose 1.
Participants are planned to be followed for up to 24 months after Dose 2, for assessments of
safety and efficacy against COVID-19. In the clinical study, participants were required to
observe a minimum interval of 14 days before and after administration of an influenza vaccine
in order to receive either placebo or COMIRNATY. In the clinical study, participants were
under
required to observe a minimum interval of 60 days before or after receipt of blood/plasma
products or immunoglobulins through to conclusion of the study in order to receive either
placebo or COMIRNATY.
The population for the analysis of the primary efficacy endpoint included 36,621 participants
the
12 years of age and older (18,242 in the COMIRNATY group and 18,379 in the placebo group)
who did not have evidence of prior infection with SARS-CoV-2 through 7 days after the second
dose. In addition, 134 participants were between the ages of 16 to 17 years of age (66 in the
Official
COMIRNATY group and 68 in the placebo group) and 1616 participants 75 years of age and
older (804 in the COMIRNATY group and 812 in the placebo group).
At the time of the primary efficacy analysis, participants had been followed for symptomatic
COVID-19 for in total 2,214 person-years for the COMIRNATY group and in total 2,222
person-years for the placebo group.
Information
There were no meaningful clinical differences in overall vaccine efficacy in participants who
were at risk of severe COVID-19 including those with 1 or more comorbidities that increase
the risk of severe COVID-19 (e.g. asthma, body mass index (BMI) ≥30 kg/m2, chronic
pulmonary disease, diabetes mellitus, hypertension).

Immunogenicity in children 5 to 11 years of age – after 2 doses
Study C4591007 is a Phase 1/2/3 study comprised of an open-label vaccine dose-finding
portion (Phase 1) and a multicentre, multinational, randomised, saline placebo-controlled,
observer-blind efficacy portion (Phase 2/3) that has enrolled participants 5 to 11 years of age.
In C4591007, an analysis of SARS-CoV-2 50% neutralising titres (NT50) 1 month after Dose
2 in a randomly selected subset of participants demonstrated effectiveness by immunobridging
of immune responses comparing children 5 to 11 years of age in the Phase 2/3 part of Study
C4591007 to participants 16 to 25 years of age in the Phase 2/3 part of Study C4591001 who

Immunogenicity in participants 18 years of age and older – after booster dose
1982
Effectiveness of a booster dose of COMIRNATY was based on an assessment of 50%
neutralising titres (NT50) against SARS-CoV-2 (USA_WA1/2020). In Study C4591001,
analyses of NT50 1 month after the booster dose compared to 1 month after the primary series
in individuals 18 to 55 years of age who had no serological or virological evidence of past
SARS-CoV-2 infection up to 1 month after the booster vaccination demonstrated
noninferiority for both GMR and difference in seroresponse rates. Seroresponse for a
participant was defined as achieving a ≥4-fold rise in NT50 from baseline (before Dose 1),
These analyses are summarised in Table 11.

General recommendations
Released
Hypersensitivity and anaphylaxis
Events of anaphylaxis have been reported. Appropriate medical treatment and supervision
should always be readily available in case of an anaphylactic reaction following the
administration of COMIRNATY.
The individual should be kept under close observation for at least 15 minutes following
vaccination. A second dose of COMIRNATY should not be given to those who have
under
experienced anaphylaxis to the first dose of COMIRNATY.
Myocarditis and pericarditis
Very rare cases of myocarditis and pericarditis have been observed following vaccination with
the
COMIRNATY. These cases have primarily occurred within 14 days following vaccination,
more often after the second vaccination, and more often, but not exclusively in younger men.
There have been reports in females. Based on accumulating data, the reporting rates of
Official
myocarditis and pericarditis after primary series in children ages 5 through <12 years are lower
than in ages 12 through 17 years. Rates of myocarditis and pericarditis in booster doses do not
appear to be higher than after the second dose in the primary series. The cases are generally
mild and individuals tend to recover within a short time following standard treatment and rest.
Cases of myocarditis and pericarditis following vaccination have rarely been associated with
severe outcomes including death.
Information
Healthcare professionals should be alert to the signs and symptoms of myocarditis and
pericarditis, including atypical presentations. Vaccinees should be instructed to seek
immediate medical attention if they develop symptoms indicative of myocarditis or pericarditis
such as (acute and persisting) chest pain, shortness of breath, or palpitations following
vaccination. Non-specific symptoms of myocarditis and pericarditis also include fatigue,
nausea and vomiting, abdominal pain, dizziness or syncope, oedema and cough. Healthcare
professionals should consult guidance and/or specialists to diagnose and treat this condition.
Act
Stress-related responses
Some individuals may have stress-related responses associated with the process of vaccination
1982
itself. Stress-related responses are temporary and resolve on their own. They may include
dizziness, fainting, palpitations, increases in heart rate, alterations in blood pressure, feeling
short of breath, tingling sensations, sweating and/or anxiety. Individuals should be advised to
bring symptoms to the attention of the vaccination provider for evaluation and precautions
should be in place to avoid injury from fainting.
Concurrent illness
Vaccination should be postponed in individuals suffering from acute severe febrile illness or
acute infection. The presence of a minor infection and/or low grade fever should not delay
vaccination.

Supersedes: pfdcocii11222
Page 3 of 32
Thrombocytopenia and coagulation disorders
As with other intramuscular injections, COMIRNATY should be given with caution in
individuals receiving anticoagulant ther apy or those with thrombocytopenia or any coagulation
disorder (such as haemophilia) bec ause bleeding or bruising may occur following an
intramuscular administration in these individuals.
Immunocompromised individuals
Released

4.6 Fertility, pregnancy and lactation
Fertility
In a combined fertility and developmental toxicity study, female rats were intramuscularly
administered COMIRNATY prior to mating and during gestation (4 full human doses of
30 micrograms each, spanning between pre-mating day 21 and gestation day 20). SARS-CoV-
2 neutralising antibodies were present in maternal animals from prior to mating to the end of
the study on postnatal day 21 as well as in fetuses and offspring. There were no vaccine related
effects on female fertility and pregnancy rate.

Pregnancy
There is limited experience with use of COMIRNATY in pregnant women. Animal studies do
not indicate direct or indirect harmful effects with respect to pregnancy, embryo/fetal
development, parturition or post-natal development (see Section 4.6 Fertility, pregnancy and
lactation, Fertility). Administration of COMIRNATY in pregnancy should only be considered
when the potential benefits outweigh any potential risks for the mother and fetus.
Released
Lactation
It is unknown whether tozinameran is excreted in human milk. A combined fertility and
developmental toxicity study in rats did not show harmful effects on offspring development
before weaning (see Section 4.6 Fertility, pregnancy and lactation, Fertility).
4.7 Effects on ability to drive and use machines

Summary of safety profile
Official
The safety of COMIRNATY was evaluated in participants 5 years of age and older in 3 clinical
studies that included 24,675 participants (comprised of 22,026 participants 16 years of age and
older, 1,131 adolescents 12 to 15 years of age and 1,518 children 5 to 11 years of age) that have
received at least one dose of COMIRNATY.
Information
Additionally, 306 existing Phase 3 participants at 18 to 55 years of age received a booster dose
of COMIRNATY approximately 6 months after the second dose in the non-placebo-controlled
booster dose portion of Study C4591001. The overall safety profile for the booster dose was
similar to that seen after 2 doses.
In Study C4591031, a placebo-controlled booster study, 5,081 participants 16 years of age and
older were recruited from Study C4591001 to receive a booster dose of COMIRNATY at least
6 months after the second dose. The overall safety profile for the booster dose was similar to
that seen after 2 doses.

5. PHARMACOLOGICAL PROPERTIES
Official
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: vaccines, other viral vaccines, ATC code: J07BX03.
Information
Mechanism of action
The nucleoside-modified messenger RNA in COMIRNATY is formulated in lipid
nanoparticles, which enable delivery of the non-replicating RNA into host cells to direct
transient expression of the SARS-CoV-2 spike (S) antigen. The mRNA codes for membrane-
anchored, full-length S with two point mutations within the central helix. Mutation of these
two amino acids to proline locks S in an antigenically preferred prefusion conformation.
COMIRNATY elicits both neutralising antibody and cellular immune responses to the antigen,
which may contribute to protection against COVID-19.

Clinical efficacy and safety
Efficacy
1982
Study C4591001 is a multicentre, multinational, Phase 1/2/3 randomised, placebo-controlled,
observer-blind dose-finding, vaccine candidate selection and efficacy study in participants 12
years of age and older. Randomisation was stratified by age: 12 to 15 years of age, 16 to 55
years of age, or 56 years of age and older, with a minimum of 40% of participants in the ≥56-
year stratum. The study excluded participants who were immunocompromised and those who
had previous clinical or microbiological diagnosis of COVID-19. Participants with pre-existing
stable disease, defined as disease not requiring significant change in therapy or hospitalisation
for worsening disease during the 6 weeks before enrolment, were included as were participants
with known stable infection with HIV, hepatitis C virus (HCV) or hepatitis B virus (HBV).

response to COMIRNATY in adolescents 12 to 15 years of age (n = 190) was non-inferior to
the immune response in participants 16 to 25 years of age (n = 170), based on results for SARS-
CoV-2 neutralising titres at 1 month after Dose 2. The geometric mean titres (GMT) ratio of
the adolescents 12 to 15 years of age group to the participants 16 to 25 years of age group was
1.76, with a 2-sided 95% CI of 1.47 to 2.10, meeting the 1.5-fold non-inferiority criterion (the

Immunogenicity in children 5 to 11 years of age – after 2 doses
Study C4591007 is a Phase 1/2/3 study comprised of an open-label vaccine dose-finding
portion (Phase 1) and a multicentre, multinational, randomised, saline placebo-controlled,
observer-blind efficacy portion (Phase 2/3) that has enrolled participants 5 to 11 years of age.
In C4591007, an analysis of SARS-CoV-2 50% neutralising titres (NT50) 1 month after Dose
2 in a randomly selected subset of participants demonstrated effectiveness by immunobridging
of immune responses comparing children 5 to 11 years of age in the Phase 2/3 part of Study
C4591007 to participants 16 to 25 years of age in the Phase 2/3 part of Study C4591001 who

Dose 2, meeting the prespecified immunobridging criteria for both the geometric mean ratio
(GMR) and the seroresponse difference with seroresponse defined as achieving at least 4-fold
rise in SARS-CoV-2 NT50 from baseline (before Dose 1).
The ratio of the SARS-CoV-2 NT50 in children 5 to 11 years of age to that of young adults 16

Immunogenicity in participants 18 years of age and older – after booster dose
1982
Effectiveness of a booster dose of COMIRNATY was based on an assessment of 50%
neutralising titres (NT50) against SARS-CoV-2 (USA_WA1/2020). In Study C4591001,
analyses of NT50 1 month after the booster dose compared to 1 month after the primary series
in individuals 18 to 55 years of age who had no serological or virological evidence of past
SARS-CoV-2 infection up to 1 month after the booster vaccination demonstrated
noninferiority for both GMR and difference in seroresponse rates. Seroresponse for a
participant was defined as achieving a ≥4-fold rise in NT50 from baseline (before Dose 1),
These analyses are summarised in Table 12.

from Study C4591001, evaluated confirmed COVID-19 cases accrued from at least 7 days after
booster vaccination up to a data cut-off date of 8 February 2022 (a period when Delta and then
Omicron was the predominant variant), which represents a median of 2.8 months (range 0.3 to
7.5 months) post-booster follow-up. Vaccine efficacy of the COMIRNATY booster dose after
the primary series relative to the placebo booster group who only received the primary series
dose was assessed. The relative vaccine efficacy information for participants 16 years of age

Immunogenicity in children 5 to 11 years of age – after booster dose
Effectiveness of a booster dose of COMIRNATY was based on an assessment of NT50 against
the reference strain of SARS-CoV-2 (USA_WA1/2020). Analyses of NT50 1 month after the
booster dose compared to before the booster dose demonstrated a substantial increase in GMTs
in individuals 5 to 11 years of age who had no serological or virological evidence of past
SARS-CoV-2 infection up to 1 month after the booster dose. This analysis is summarised in
Table 14.

Immunogenicity in children 5 to 11 years of age on the Omicron variant (B1.1.529) –
after booster dose
The neutralising GMTs against both the Omicron variant (B1.1.529) and reference strain were
substantially increased after booster vaccination compared with after the 2-dose primary series.
At 1-month post-Dose 2, the observed neutralising GMTs for the Omicron variant (B1.1.529)

General recommendations
Released
Hypersensitivity and anaphylaxis
Events of anaphylaxis have been reported. Appropriate medical treatment and supervision
should always be readily available in case of an anaphylactic reaction following the
administration of COMIRNATY.
The individual should be kept under close observation for at least 15 minutes following
vaccination. A second dose of COMIRNATY should not be given to those who have
under
experienced anaphylaxis to the first dose of COMIRNATY.
Myocarditis and pericarditis
Very rare cases of myocarditis and pericarditis have been observed following vaccination with
the
COMIRNATY. These cases have primarily occurred within 14 days following vaccination,
more often after the second vaccination, and more often, but not exclusively in younger men.
There have been reports in females. Based on accumulating data, the reporting rates of
Official
myocarditis and pericarditis after primary series in children ages 5 through <12 years are lower
than in ages 12 through 17 years. Rates of myocarditis and pericarditis in booster doses do not
appear to be higher than after the second dose in the primary series. The cases are generally
mild and individuals tend to recover within a short time following standard treatment and rest.
Cases of myocarditis and pericarditis following vaccination have rarely been associated with
severe outcomes including death.
Information
Healthcare professionals should be alert to the signs and symptoms of myocarditis and
pericarditis, including atypical presentations. Vaccinees should be instructed to seek
immediate medical attention if they develop symptoms indicative of myocarditis or pericarditis
such as (acute and persisting) chest pain, shortness of breath, or palpitations following
vaccination. Non-specific symptoms of myocarditis and pericarditis also include fatigue,
nausea and vomiting, abdominal pain, dizziness or syncope, oedema and cough. Healthcare
professionals should consult guidance and/or specialists to diagnose and treat this condition.
Act
Stress-related responses
Some individuals may have stress-related responses associated with the process of vaccination
itself. Stress-related responses are temporary and resolve on their own. They may include
1982
dizziness, fainting, palpitations, increases in heart rate, alterations in blood pressure, feeling
short of breath, tingling sensations, sweating and/or anxiety. Individuals should be advised to
bring symptoms to the attention of the vaccination provider for evaluation and precautions
should be in place to avoid injury from fainting.
Concurrent il ness
Vaccination should be postponed in individuals suffering from acute severe febrile illness or
acute infection. The presence of a minor infection and/or low grade fever should not delay
vaccination.

Thrombocytopenia and coagulation disorders
As with other intramuscular injections, COMIRNATY should be given with caution in
individuals receiving anticoagulant ther apy or those with thrombocytopenia or any coagulation
disorder (such as haemophilia) because bleeding or bruising may occur following an
intramuscular administration in these individuals.
Immunocompromised individuals
Released
The efficacy, safety and immunogenicity of COMIRNATY has not been assessed in
immunocompromised individuals, including those receiving immunosuppressant therapy. The
efficacy of COMIRNATY may be lower in immunosuppressed individuals.
Duration of protection
The duration of protection afforded by COMIRNATY is unknown as it is still being determined
by ongoing clinical trials.

Fertility
In a combined fertility and developmental toxicity study, female rats were intramuscularly
administered COMIRNATY prior to mating and during gestation (4 full human doses of
30 micrograms each, spanning between pre-mating day 21 and gestation day 20). SARS-CoV-
2 neutralising antibodies were present in maternal animals from prior to mating to the end of
the study on postnatal day 21 as well as in fetuses and offspring. There were no vaccine related
effects on female fertility and pregnancy rate.

Pregnancy
There is limited experience with use of COMIRNATY in pregnant women. Animal studies do
not indicate direct or indirect harmful effects with respect to pregnancy, embryo/fetal
development, parturition or post-natal development (see Section 4.6 Fertility, pregnancy and
lactation, Fertility). Administration of COMIRNATY in pregnancy should only be considered
when the potential benefits outweigh any potential risks for the mother and fetus.
Released
Lactation
It is unknown whether tozinameran is excreted in human milk. A combined fertility and
developmental toxicity study in rats did not show harmful effects on offspring development
before weaning (see Section 4.6 Fertility, pregnancy and lactation, Fertility).

Official
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: vaccines, other viral vaccines, ATC code: J07BX03.
Information
Mechanism of action
The nucleoside-modified messenger RNA in COMIRNATY is formulated in lipid
nanoparticles, which enable delivery of the non-replicating RNA into host cells to direct
transient expression of the SARS-CoV-2 spike (S) antigen. The mRNA codes for membrane-
anchored, full-length S with two point mutations within the central helix. Mutation of these
two amino acids to proline locks S in an antigenically preferred prefusion conformation.
COMIRNATY elicits both neutralising antibody and cellular immune responses to the antigen,
which may contribute to protection against COVID-19.

Efficacy
1982
Study C4591001 is a multicentre, multinational, Phase 1/2/3 randomised, placebo-controlled,
observer-blind dose-finding, vaccine candidate selection and efficacy study in participants 12
years of age and older. Randomisation was stratified by age: 12 to 15 years of age, 16 to 55
years of age, or 56 years of age and older, with a minimum of 40% of participants in the ≥56-
year stratum. The study excluded participants who were immunocompromised and those who
had previous clinical or microbiological diagnosis of COVID-19. Participants with pre-existing
stable disease, defined as disease not requiring significant change in therapy or hospitalisation
for worsening disease during the 6 weeks before enrolment, were included as were participants
with known stable infection with HIV, hepatitis C virus (HCV) or hepatitis B virus (HBV).

Immunogenicity in children 5 to 11 years of age – after 2 doses
Study C4591007 is a Phase 1/2/3 study comprised of an open-label vaccine dose-finding
portion (Phase 1) and a multicentre, multinational, randomised, saline placebo-controlled,
observer-blind efficacy portion (Phase 2/3) that has enrolled participants 5 to 11 years of age.
In C4591007, an analysis of SARS-CoV-2 50% neutralising titres (NT50) 1 month after Dose
2 in a randomly selected subset of participants demonstrated effectiveness by immunobridging
of immune responses comparing children 5 to 11 years of age in the Phase 2/3 part of Study
C4591007 to participants 16 to 25 years of age in the Phase 2/3 part of Study C4591001 who

Dose 2, meeting the prespecified immunobridging criteria for both the geometric mean ratio
(GMR) and the seroresponse difference with seroresponse defined as achieving at least 4-fold
rise in SARS-CoV-2 NT50 from baseline (before Dose 1).

Immunogenicity in participants 18 years of age and older – after booster dose
1982
Effectiveness of a booster dose of COMIRNATY was based on an assessment of 50%
neutralising titres (NT50) against SARS-CoV-2 (USA_WA1/2020). In Study C4591001,
analyses of NT50 1 month after the booster dose compared to 1 month after the primary series
in individuals 18 to 55 years of age who had no serological or virological evidence of past
SARS-CoV-2 infection up to 1 month after the booster vaccination demonstrated
noninferiority for both GMR and difference in seroresponse rates. Seroresponse for a
participant was defined as achieving a ≥4-fold rise in NT50 from baseline (before Dose 1),
These analyses are summarised in Table 12.

Immunogenicity in children 5 to 11 years of age – after booster dose
Effectiveness of a booster dose of COMIRNATY was based on an assessment of NT50 against
the reference strain of SARS-CoV-2 (USA_WA1/2020). Analyses of NT50 1 month after the
booster dose compared to before the booster dose demonstrated a substantial increase in GMTs
in individuals 5 to 11 years of age who had no serological or virological evidence of past
SARS-CoV-2 infection up to 1 month after the booster dose. This analysis is summarised in
Table 14.

Immunogenicity in children 5 to 11 years of age on the Omicron variant (B1.1.529) –
after booster dose
The neutralising GMTs against both the Omicron variant (B1.1.529) and reference strain were
substantially increased after booster vaccination compared with after the 2-dose primary series.
At 1-month post-Dose 2, the observed neutralising GMTs for the Omicron variant (B1.1.529)
and reference strain were 27.6 and 323.8, respectively. At 1-month post-Dose 3, the observed
neutralising GMTs for the Omicron variant (B1.1.529) and reference strain were 614.4 and
