1. How long should I wait for a COVID-19 booster after getting infected?​

You can delay your vaccine by 28 days from when your symptoms started or when you received a positive COVID-19 test. However, for enhanced efficacy, it is advised to receive your next vaccine dose three months after the infection or at the suggested interval for your following dose, whichever occurs later.7

Protection begins one or two weeks after receiving the booster shot.3

3. Where can I find COVID-19 Vaccination Locations near me?​

4. How do I protect myself from COVID-19 while travelling?

In enclosed areas of public transportation (such as buses, trains, planes and ferries) and transportation hubs (such as airports, stations and seaports), everyone 2 years of age and older should wear a high-quality mask or respirator, especially in crowded or inadequately ventilated areas like airport jetways. This recommendation applies regardless of vaccination status.6

5. Why do I need booster shots?

Over time, there is a reduction in protection offered by vaccines against mild and moderate infections of COVID-19. Booster shots are administered to remind the body's immune system about the virus it needs to defend against. In the year 2023/2024, elderly individuals or those who are at a high risk for severe disease who have completed their primary course are recommended by the Singapore Government to receive another dose of the updated vaccine around 1 year (and no earlier than 5 months) after the last dose received. Individuals aged 6 months and above, in particular, healthcare workers, as well as household members and caregivers of medically vulnerable individuals who have completed their primary course are also encouraged to get an additional dose of the updated vaccine around 1 year (and no earlier than 5 months) after the last dose received4

  • Chronic lung conditions, including severe asthma

If you experience any symptoms, please consult a healthcare professional.1​

13. Is it necessary to get the same vaccine brand for each dose?

Occasionally, the formulation of a COVID-19 vaccine may be modified to address newer virus variants. If you are due for a vaccine dose, it is recommended to receive the updated version of the vaccine. There is no requirement for all your vaccine doses to have the same composition, however, for the initial two doses of Pfizer-BioNTech, Moderna or Novavax vaccines, it is advisable to use the same brand.
