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

You can enter your postal code or street name to find a vaccination location here.

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

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 

Conditions at high risk for severe disease include:⁹

• Diabetes
• Heart conditions such as heart failure, ischemic heart disease, cardiomyopathy
• Chronic lung conditions, including severe asthma
• Chronic liver conditions, including cirrhosis
• Chronic kidney conditions, including dialysis
• Chronic neurologic conditions, including stroke
• Cancer or active treatment
• Blood conditions such as thalassemia and sickle cell anemia
• Immunodeficiencies, including HIV infection
• Obesity (BMI > 30)
• Genetic or metabolic conditions, including Down’s syndrome and cystic fibrosis
• Persons on non-cancer immunosuppressive treatment
• Pregnancy (any trimester)

• Aged 5-11 years: Pfizer-BioNTech vaccine only
• Aged 12 and older: Pfizer-BioNTech and Novavax vaccines
• Aged 18 years and above: Pfizer-BioNTech, Moderna, Novavax or Sinovac vaccines

• Singpass User: You can view your vaccination records by logging in to the HealthHub app or the Notarise website using your Singpass account.⁵

You do not need to restart your vaccination if you miss a dose. The timeframe to get fully vaccinated is not strict, so you should receive your vaccine dose as soon as possible for optimal protection.¹⁰

The main way COVID-19 spreads is through respiratory particles from infected people, which are emitted when a person coughs, sneezes, talks, or even sings. Infection can spread when these respiratory particles directly or indirectly (through contaminated surfaces) come in contact with the eyes, nose, or mouth.^2​

Both COVID-19 and influenza (Flu) are contagious respiratory diseases that have caused mortality worldwide, although they are brought on by different viruses. Flu is caused by an infection with an influenza virus, whereas COVID-19 is caused by the COVID-19 virus. The symptoms of the flu and COVID-19 may be difficult to differentiate. If you experience any symptoms, please consult a healthcare professional.^1​

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. Any subsequent doses can be of different brands, if applicable.⁷

If you are feel well and are asymptomatic, you may proceed with your COVID-19 vaccination appointment. If you have any symptoms or feel unwell, you may delay your vaccination by 28 days to 3 months. For any further concerns, please speak to a healthcare professional.^7,8
