Timing your flu vaccination with your COVID-19 vaccination

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 14 days.
Timing scenarios
If you have not had any COVID-19 vaccine: wait at least 14 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 14 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 14 days prior to your second dose OR 14 days after your second dose.
If you have received one dose of COVID-19 Pfizer vaccine: do not have your flu vaccine until at least 14 days after your second dose of Pfizer vaccine.
