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 24 January 2025 for information regarding Pfizer
vaccine adverse side effects. You requested:
“Please can you supply information on how many adverse side effects or deaths from
batch number EP9605 and batch ET3045-014”
Your request is refused under section 18(g)(i) of the Act as the information requested is not held
by the Ministry and there are no grounds for believing it is held by another agency subject to the
Act. The Ministry only holds information related to batch numbers when the batch number is
reported as part of the adverse event following immunisation (AEFI) report. Not all adverse
events following immunisation represent side effects and not all side effects are reported.
If you wish to discuss any aspect of your request with us, including this decision, please feel
free to contact the OIA Services Team on: [email address].
Under section 28(3) of the Act, you have the right to ask the Ombudsman to review any
decisions made under this request. The Ombudsman may be contacted by email at:
[email address] or by calling 0800 802 602.
Please note that this response, with your personal details removed, may be published on the
Manatū Hauora website at:
