COVID-19 Vaccine Safety, Myocarditis, and Transparency
SPENCER JONES made this Official Information request to Ministry of Health
Currently waiting for a response from Ministry of Health, they must respond promptly and normally no later than (details and exceptions).
From: SPENCER JONES
Dear Ministry of Health,
Under the Official Information Act 1982, I request the following information held by the Ministry of Health (MoH), Medsafe, or Health New Zealand (Te Whatu Ora) regarding COVID-19 vaccine safety, myocarditis cases, and transparency processes. To facilitate a timely response, I have prioritised specific data and documents relevant to public interest in vaccine safety.
This request is submitted following a comprehensive review of prior OIA responses on FYI.org.nz regarding COVID-19 vaccine safety, myocarditis reporting, and Medsafe transparency. It is structured to address public concerns about delayed disclosures and missing case breakdowns, and seeks specific documents referenced in earlier replies.
The request is supported by ongoing public interest and is intended to ensure accountable, science-based policy transparency for the New Zealand public.
1. Myocarditis Case Data (2020–2024)
• Total number of myocarditis cases reported in New Zealand annually from 2020 to 2024, as recorded in Medsafe’s Adverse Events Following Immunization (AEFI) system or other databases (e.g., National Minimum Dataset).
• For 2021–2022, a detailed breakdown of the 405 myocarditis cases reported in Medsafe’s AEFI reports (OIA H202201773), including:
• • Number of cases attributed to COVID-19 infection vs. COVID-19 vaccination.
• • Vaccination status of each case (e.g., Pfizer/Comirnaty, other vaccines, unvaccinated, or unknown).
• • Age and gender demographics of cases.
• For cases not attributed to vaccination, the methodology or criteria used to determine causality (e.g., diagnostic tests, temporal association).
2. Vaccine Safety Monitoring Processes
• A description of Medsafe’s statistical methods for analyzing adverse event reports, including whether Empirical Bayesian (EB) data mining, Proportional Reporting Ratio (PRR), or other quantitative methods are used, as compared to U.S. CDC/FDA practices.
• Copies of any EB, PRR, or equivalent statistical analyses of COVID-19 vaccine adverse events (redacted for proprietary information if necessary) conducted from 2020 to 2024.
• A list of international studies or data sources (e.g., U.S. VAERS, WHO VigiBase) relied upon by Medsafe or the COVID-19 Vaccine Technical Advisory Group (CVTAG) to assess myocarditis risks, with specific report titles or links where available.
3. Pfizer Safety Data
• Confirmation of whether Medsafe reviewed Pfizer’s “5.3.6 Cumulative Analysis of Post-Authorization Adverse Event Reports” (through February 28, 2021) prior to approving the Pfizer-BioNTech vaccine.
• A list of key safety reports or evidence provided by Pfizer to Medsafe for provisional and extended approvals (2021–2023), as referenced in OIA H202117908, including document titles and dates (redacted summaries if full disclosure is restricted).
• Details of any requests made by Medsafe to Pfizer for real-time safety data updates post-global rollout (December 2020–December 2021).
4. Transparency and OIA Handling
• Copies of MoH or Medsafe guidelines for handling OIA requests related to COVID-19 vaccine safety, specifically criteria for applying Section 9(2) exemptions (e.g., commercial sensitivity, privacy).
• Total number of OIA requests related to COVID-19 vaccine safety received from 2020 to 2024, with a breakdown by outcome (e.g., fully granted, partially granted, refused, delayed beyond 20 working days).
• Explanation of why specific myocarditis data (e.g., vaccination status for 132 cases in OIA H202201773) was not provided in prior responses, and confirmation of whether such data is now available.
5. CVTAG and CV-ISMB Discussions
• Minutes, reports, or correspondence from CVTAG and the COVID-19 Vaccine Independent Safety Monitoring Board (CV-ISMB) discussing myocarditis risks from 2020 to 2024, beyond those provided in OIA H202115672.
• Data or studies relied upon by CV-ISMB to conclude no link between menstrual disorders and Comirnaty in 2021 (OIA H202218890), and any reassessments following the U.S. NIH study (published 2022) confirming a link.
Additional Notes
• If information is withheld under OIA exemptions, please provide the specific section, justification, and a summary of withheld documents (e.g., titles, dates, page counts) to ensure transparency.
• If data is unavailable, please clarify whether it was not collected, is incomplete, or is held by another entity (e.g., Health NZ), and indicate where such data might be accessed.
• Please provide electronic copies of documents or links to publicly available sources where applicable.
• For clarification, I can be contacted via fyi.org.nz’s messaging system, maintaining anonymity as a public requester.
Given the public interest in vaccine safety transparency, I request a response within the statutory 20 working days. I understand the MoH may face high request volumes and am willing to refine the scope if needed to facilitate timely processing.
Yours faithfully,
SPENCER JONES

I look forward to reading the results of this request.
A couple of years back I downloaded the myo/peri data which accompanied safety report #41 and compared it with the numbers in the report (they were inconsistent), and I presented it graphically against expected rates (https://substack.com/@splendidmarvellous...). Given the results, I struggle to understand why this information was not made public.
