This advice is based on a new recommendation of the Australian Technical Advisory Group on Immunisation (ATAGI), following new information on evidence of a rare but serious side effect of thrombosis in younger people.
The advice states:
- ATAGI recommends that the COVID-19 vaccine by Pfizer is preferred over COVID-19 Vaccine AstraZeneca in adults aged under 50 years.
- COVID-19 Vaccine AstraZeneca can be used in adults aged under 50 years – where the benefits are likely to outweigh the risks for that individual and the person has made an informed decision based on an understanding of the risks and benefits.
- People who have had the first dose of COVID-19 Vaccine AstraZeneca without any serious adverse effects can be given the second dose, including adults under 50 years.
Both ATAGI and the Therapeutic Goods Administration (TGA) will continue to monitor the situation closely.
From tomorrow, Friday 8 April, 2021, when WA vaccination clinics reopen across the State, AstraZeneca vaccinations will only be given to people over the age of 50.
People under 50 who are booked in to receive their AstraZeneca vaccine will have their appointments cancelled. If you have a booking tomorrow or in coming days, please do not show up for your appointment.
