There is no particular requirement regarding the order of receiving a dose of flu vaccine and a dose of a COVID-19 vaccine. However, the preferred minimum time between a dose of flu vaccine and a dose of COVID-19 Vaccine (Pfizer or AstraZeneca) is 7 days.



Timing scenarios

If you have not had any COVID-19 vaccine: wait at least 7 days after your flu vaccine to receive your first dose of COVID-19 vaccine

If you have received one dose of COVID-19 AstraZeneca vaccine: wait at least 7 days after this first dose before having your influenza vaccine. 

The recommended interval (time) between the first and second dose of AstraZeneca is 12 weeks – ensure you have your influenza vaccine more than 7 days prior to your second dose OR 7 days after your second dose.

If you have received one dose of COVID-19 Pfizer vaccine: wait 7 days after your second dose of Pfizer vaccine OR 7 days after your second dose.
