AstraZeneca vaccine

Published 1 December 2021

If people are interested in having the AstraZeneca COVID-19 vaccine, IMAC recommends they go to their GP to discuss, and to obtain a prescription and consent form. This gives them the opportunity to consider any adverse reactions they have had to vaccines previously, the benefits of vaccination, and risks of potential adverse reactions for AstraZeneca. 

People wanting an AstraZeneca vaccine can book online from 26 November on bookmyvaccine. There will be a limited number of clinics in each DHB offering this vaccine.

These specified clinics will also have the opportunity on site to offer prescriptions and consent forms if people prefer to go directly to a clinic rather than via their general practice.

Written consent is recommended for all AstraZeneca doses, and a prescription is required when AstraZeneca is given as a mixed schedule with another COVID-19 vaccine. The reason for this is that a mixed schedule is ‘offlabel’ usage. While there are not expected to be any safety concerns with using a mixed schedule, it does not yet have Medsafe approval.

Potential side effects of AstraZeneca
TTS is a rare but serious condition causing blood clots and bleeding that has been seen overseas in a small number of people who have had the AstraZeneca or Janssen vaccines. There is currently no evidence of an increased risk of thrombosis or TTS with the Pfizer vaccine. The information in these brochures explains the differences between thrombosis (blood clots) and TTS. These educational pieces also contain information on how to identify TTS and when to seek medical attention. Both brochures have been published on the Medsafe website. The consumer-facing brochure is published on the Ministry of Health website, alongside information about the AstraZeneca vaccine.
