If you have recovered from a COVID-19 infection, it is recommended that you receive a single dose of an mRNA vaccine at least 3 months after the date of your diagnosis, if you have not already completed your vaccination. There is evidence that a single dose of mRNA would further boost your immunity against COVID-19.

If you are medically ineligible to receive the mRNA vaccine, you may take two doses of Sinovac-CoronaVac vaccine spaced 28 days apart, from 3 months after the date of your diagnosis.

No additional booster dose is recommended at this time.

You are recommended to receive three doses of the Sinovac-CoronaVac COVID-19 vaccine to achieve vaccine protection and be considered fully vaccinated. The third dose should be received from 90 days after the second dose.

Persons who had received two doses of Sinovac-CoronaVac/Sinopharm are recommended to receive a dose of the PSAR mRNA vaccine to complete their primary vaccination series if they are not contraindicated to receive the mRNA vaccines.

To provide enough time for you to get your third dose and maintain your vaccination status, all individuals who have taken two doses of Sinovac-CoronaVac will be regarded as fully vaccinated for 4 months after the second dose, or until 31 December 2021, whichever is later.
