Having COVID-19 does not provide the same level of immunity as getting immunised.
If you have had COVID-19 and are eligible for a booster, it is recommended you wait 6 months after you tested positive.
Why you need to wait between infection and immunisation
After you have had COVID-19 your antibody levels will be high from your immune system’s response to the infection. This will give you some protection against COVID-19.
After 6 months, your antibody levels have likely dropped and, if you are due to have a vaccine, it is a good time to boost your immunity.
If you get a vaccine soon after you have had COVID-19, you may not get all the benefits from it because your antibody levels are already high.
If you are at higher risk of severe illness from COVID-19, we recommend you talk to your doctor or specialist for advice on the timing of your next dose. It may be appropriate for you to get your COVID-19 vaccine sooner than 6 months.
