Dear Ministry of Health,
I refer to a response to another OIA which is H202112324 CV-TAG minutes https://fyi.org.nz/request/16691/respons... which discusses dosing intervals for the pfizer vax in lots of places:

On page 8: "A request was received for administrative and IT purposes to define a maximum allowable time interval between doses. The suggestion based on current evidence and recommendations from ATAGI and the US CDC is for six weeks. It is recommended that the second dose be given as close to the three-week time as possible. The Ministry will work with the CIR team to ensure that this administrative upper limit on the interval between doses isn’t interpreted as a clinical recommendation."

On p32: "options for the second dose may include 1) proceeding with the second dose of the Pfizer Covid-19 vaccine after a longer interval between doses"

p40 "Tuesday 27 July 2021

2.0 Myocarditis Recommendations Update
The final memo on Myocarditis after Pfizer mRNA vaccination was shared with CV TAG and discussed.
• The final memo included input and advice from Medsafe.
• The Director-General has received the recommendations, and an implementation plan is
currently being prepared within the Ministry, once the recommendations have been agreed by Ministers
• CV TAG discussed the data supporting longer dosing intervals for Pfizer; Data showed
higher immunogenicity was associated with an extended dosing interval (median 10 weeks) compared to the usual 3-4 weeks.
• CV TAG discussed the recommended dosing interval for people under 30 years. CV TAG discussed the while an 8-week interval is recommended for this age group, administering the second dose between 6 and 12 weeks is acceptable, and that the exact timing is a programming decision.
• It was agreed that all changes must communicated in a way to provide clarity."

There are many dosing intervals suggested in the CV Tag minutes in 2021 for the pfizer covid vax in https://fyi.org.nz/request/16691/respons...

1. Would you please share the clinical trial report that supports a 10 week dosing interval?
2. Would you please share the clinical trial report that supports a 3-4 week dosing interval?
3. Would you please share the clinical trial report that supports a 6 week dosing interval?
4 Would you please share the clinical trial report that supports a 8 week dosing interval?
5 Would you please share the clinical trial report that supports a 12 week dosing interval?

I could not see any such reports on https://clinicaltrials.gov/search?term=c...

Yours faithfully,

Erika Whittome
