2nd Booster Shot Singapore: What You Need to Know
If you’re living in Singapore, you may be wondering about the eligibility and accessibility of the 2nd booster shot for COVID-19. As of June 2024, medically vulnerable persons with specific health conditions may self-declare their health conditions to receive their second booster by walking into any Vaccination Centre, PHPCs, and polyclinics that offer vaccinations.

To facilitate the uptake of the second booster, EC19V recommends that persons aged 18 years and older, who have health conditions that make them medically vulnerable to severe COVID-19, can receive the second booster without the need for a physician’s referral. Additionally, eligible individuals aged 80 years and above may walk in to any Vaccination Centre or participating Public Health Preparedness Clinics (PHPCs) or Polyclinics to receive their second booster dose.
It’s important to understand the vaccine information and effectiveness of the 2nd booster shot for COVID-19. The National Centre for Infectious Diseases (NCID) is conducting a clinical trial of different booster vaccines (Pfizer, Moderna, or Novavax) to understand the advantages of the different combinations.

Vaccine Information and Effectiveness

Available COVID-19 Vaccines in Singapore
In Singapore, there are currently four COVID-19 vaccines approved for use: Pfizer-BioNTech/Comirnaty, Moderna/Spikevax, Novavax/Nuvaxovid, and Sinovac-Coronavac. Each vaccine has been shown to be effective in preventing COVID-19 infection and reducing the severity of illness.
Understanding the Need for a Second Booster
After receiving the initial two doses of the COVID-19 vaccine, it is recommended to receive a second booster shot to enhance your immune response and provide additional protection against the virus. The dosing interval for the second booster shot varies depending on the type of vaccine received.
For Pfizer-BioNTech/Comirnaty and Novavax/Nuvaxovid vaccines, the second booster shot should be given no less than 21 days after the first dose. For Moderna/Spikevax and Sinovac-Coronavac vaccines, the second booster shot should be given no less than 28 days after the first dose.
Studies have shown that the second booster shot significantly enhances vaccine protection and effectiveness. For example, the latest local evidence has shown that the first booster shot reduced the risk of severe disease by 94% for those aged 70-79 years and by 97% for those aged 60-69 years. The second booster shot further reduced the risk to 97% and 98% respectively.
To facilitate uptake of the second booster shot, individuals who have health conditions that make them medically vulnerable to severe COVID-19 can receive the second booster without the need for a physician’s referral. Additionally, those who are at risk for exposure to COVID-19 or severe disease may receive the second dose earlier than eight weeks after the first dose.
It is important to note that while the COVID-19 vaccine is highly effective, it is not 100% effective. It is still possible to contract the virus even after being fully vaccinated. However, the vaccine has been shown to significantly reduce the severity of illness and prevent hospitalization and death.
In conclusion, receiving the second booster shot is an important step in enhancing your immune response and providing additional protection against COVID-19. It is recommended to follow the dosing interval guidelines for your specific vaccine and to consult with your healthcare provider if you have any questions or concerns.
