Response to your request for official information
Thank you for your request under the Official Information Act 1982 (the Act) to the Ministry of
Health – Manatū Hauora (the Ministry) on 23 July 2025 for:
“I refer to your webpage from 2021 which says:
"mRNA vaccines have been in development for decades
mRNA vaccines have been developed through major international collaboration.
Researchers have studied and worked with mRNA vaccines for decades. This includes
studies for vaccines against flu, Zika, rabies and cytomegalovirus (CMV).
Scientists have also researched past coronavirus infections (SARS and MERS). Once
scientists identified the coronavirus that causes COVID-19, they could quickly adapt the
technology for COVID-19.
Although it’s relatively new technology, this vaccine has gone through all the usual safety
checks and regulations.
This includes international clinical trials to help demonstrate the efficacy and safety of the
vaccine. The Pfizer vaccine is being used worldwide and continually and closely monitored
for effectiveness and safety."
