Mr Richards made this Official Information request to Ministry of Health

This request has an unknown status. We're waiting for Mr Richards to read recent responses and update the status.

From: Mr Richards

Dear Ministry of Health,

Under the Official Information Act 1982 I request the following information:

1- All documents, briefings, minutes, emails, risk assessments, modelling, or internal advice prepared or considered by the Ministry of Health, Te Whatu Ora, or the Immunisation Advisory Centre (IMAC) when deciding — in the 27 March 2026 amendments to Chapter 5 of the Immunisation Handbook — to retain a routine recommendation for a primary COVID-19 vaccine course (one dose for healthy previously unvaccinated individuals aged 5 years and over; two doses for severely immunocompromised individuals aged 5 years and over), while simultaneously advising that additional doses are “not routinely recommended” for healthy adults aged 30–64 years due to lower clinical risk of severe infection and high population hybrid immunity.
2- Any epidemiological modelling, cohort studies, or risk-benefit analyses (using 2025–2026 data) assessing the incremental benefit of a primary dose (or two-dose primary course) in previously unvaccinated healthy or immunocompromised individuals against severe COVID-19 outcomes, hospitalisation, or death under current endemic conditions with LP.8.1-lineage strains and widespread hybrid immunity.
3- The most recent surveillance data (2025–2026) on severe COVID-19 outcomes in the remaining unvaccinated population (including those eligible for a primary course) compared with those possessing hybrid immunity, stratified by age group, comorbidity status, and ethnicity.
4- Updated analyses of adverse event rates (particularly myocarditis/pericarditis and any other serious events) following a primary COVID-19 vaccine dose (or two-dose course) in previously unvaccinated healthy or immunocompromised individuals aged 5–64 years, including comparison to infection-related risks in 2026.
5- Any cost-effectiveness, health-economic, or resource-allocation assessments for continuing to recommend and publicly fund primary COVID-19 vaccination (one- or two-dose courses) for previously unvaccinated individuals when routine additional-dose recommendations have been narrowed for the same low-risk groups.
6- Any internal advice or modelling addressing (a) equity impacts (including for Māori and Pacific populations) of retaining the current primary-course recommendation versus (b) moving the primary course to a shared clinical decision-making / optional model only, consistent with the approach taken for additional doses in healthy 30–64 year-olds.
7- All correspondence, briefings, advice, or assessments exchanged between the Ministry of Health / Te Whatu Ora and the New Zealand Defence Force (NZDF) concerning NZDF’s “further review” of its baseline vaccination schedule triggered by the 27 March 2026 Immunisation Handbook changes. This includes any evaluation of how the risk-stratified approach and reduced routine recommendations for healthy adults apply to NZDF serving members and recruits, with specific reference to NZDF OIA-2026-5687 and follow-up request 34315 (including impacts on recruitment, retention, the ~164 previously discharged personnel, and NZDF’s status as the only remaining Five Eyes nation with a COVID-19 baseline requirement).

I request the information in electronic format where possible. If any part of this request is refused in whole or in part, please provide the specific withholding grounds under the OIA and the public interest considerations taken into account for each refusal.Thank you for your assistance. I look forward to your response within the statutory 20 working days.Yours sincerely,

Yours faithfully,
Mr Richards.

(or two-dose primary course) in previously unvaccinated healthy or

hospitalisation, or death under current endemic conditions with
LP.8.1-lineage strains and widespread hybrid immunity.

3- The most recent surveillance data (2025–2026) on severe COVID-19

6- Any internal advice or modelling addressing (a) equity impacts

Kia ora Mr Richards,
 
Thank you for your request of 22 April 2026 for the following information:
 

2- Any epidemiological modelling, cohort studies, or risk-benefit analyses
(using 2025–2026 data) assessing the incremental benefit of a primary dose
(or two-dose primary course) in previously unvaccinated healthy or
immunocompromised individuals against severe COVID-19 outcomes,
hospitalisation, or death under current endemic conditions with
LP.8.1-lineage strains and widespread hybrid immunity.

3- The most recent surveillance data (2025–2026) on severe COVID-19
outcomes in the remaining unvaccinated population (including those
eligible for a primary course) compared with those possessing hybrid
immunity, stratified by age group, comorbidity status, and ethnicity.

6- Any internal advice or modelling addressing (a) equity impacts
(including for Māori and Pacific populations) of retaining the current
primary-course recommendation versus (b) moving the primary course to a
shared clinical decision-making / optional model only, consistent with the
approach taken for additional doses in healthy 30–64 year-olds.

 
We are writing to inform you that parts 2 and 6 of your request asks for
information which is more closely aligned with the functions of the
Immunisation Advisory Centre (IMAC).
For this reason, Health New Zealand has decided to partially transfer your
request under section 14(b)(ii) of the Official Information Act (OIA). We
apologise for not transferring these parts of your request sooner, when we
transferred part 1 to IMAC.
You can expect a response from IMAC in due course. They can be contacted
at [1][email address]
 
Under section 28(3) of the OIA you have the right to ask the Ombudsman
to review any decisions made under this request. 
The Ombudsman may be contacted
by email at: [2][email address] or by calling 0800 802 602. 
If you have any queries related to this request, please do not hesitate to
get in touch.
