The minimum time between COVID-19 vaccines changes depending on how many COVID-19 vaccinations you’ve already had, if you’ve had a COVID-19 infection in the last 6 months, and what vaccine type you’re getting. Some vaccine combinations may also require a prescription.

Booster doses for ages 30 and over
If you are aged 30 and over, you can have a booster regardless of the number of boosters you have already had.
To get a booster:
- you must have had at least your first 2 COVID-19 vaccinations
- it’s recommended you wait at least 6 months since your last COVID-19 vaccine
- it’s recommended you wait at least 6 months if you have had a COVID-19 infection.
For boosters, the bivalent Pfizer vaccine is preferred. This is an updated vaccine targeting Omicron.
If you do not want to have the bivalent vaccine, you can ask for the original Pfizer vaccine when you arrive for your vaccination.
Adults aged 18 and over can also choose Novavax. This is available at limited sites.
The 6 month gap remains the same regardless of which vaccine type you’d like for your booster.

Shortening recommended gaps
Recommended gaps can be shortened in certain circumstances, such as prior to immunosuppression treatment or international travel. This will need to be discussed with your usual doctor, nurse, or healthcare provider.
How to get a prescription
If you need a prescription, before your appointment visit your preferred doctor or healthcare provider to discuss your options.
It is also possible to get a prescription at a vaccinating Novavax clinic when you arrive for your appointment – first, you’ll need to talk with the vaccination site’s clinical lead.
Severely immunocompromised people who wish to receive a third primary dose will need to get a prescription from their usual healthcare provider. We recommend you schedule a free appointment with your usual healthcare provider.
