2. Is only one dose of vaccine needed if I have recovered from Covid-19 infections?
According to the current recommendation of the Joint Scientific Committees of Emerging and Zoonotic Diseases and Vaccine Preventable Diseases, persons recovered from COVID-19 infection is recommended to receive only one dose of COVID-19 vaccine for furthering their personal protection.

Persons who wish to receive mRNA vaccine (Comirnaty(BioNTech)) should wait for at least 90 days after being discharged from COVID-19 infection. Whereas, persons who wish to receive inactivated vaccine (CoronaVac (Sinovac)) should wait for at least 180 days after being discharged.

Members of the public are advised to complete both doses of the series with the same product when possible.

In exceptional situations where the vaccine recipient is unable to complete the series with the same type of vaccine (e.g. due to anaphylaxis after the first dose; or if the vaccine is no longer available or accessible), vaccination with another COVID-19 vaccine may be considered on a case-by-case basis.

5. What is the age limit for vaccination?
Comirnaty(BioNTech) vaccine is indicated for use in individuals aged 12 years or older; and Sinovac vaccine is indicated for use in individuals aged 18 years or older.
