Vaccine Types and Effectiveness

Comparison of Covid-19 Vaccines
There are several Covid-19 vaccines available in Singapore, including Pfizer-BioNTech/Comirnaty, Moderna/Spikevax, Novavax/Nuvaxovid, and Sinovac-Coronavac. These vaccines have been authorized by the Health Sciences Authority (HSA) for use in Singapore. While all these vaccines are effective in preventing severe illness and hospitalization, some may offer better protection against certain variants of the virus.
Efficacy of the Fourth Booster Shot
If you have already received two doses of the Pfizer-BioNTech or Moderna/Spikevax vaccine, it is recommended that you receive a third booster shot after six months to ensure maximum protection against Covid-19. Recent studies have shown that a fourth booster shot can provide even greater protection against the virus, especially for those who are immunocompromised or at high risk of exposure to the virus.
Vaccination Recommendations
It is recommended that you receive the same type of vaccine for your booster shot as your primary vaccination. However, if the same vaccine is not available, you can receive a different type of vaccine. The minimum recommended interval between the second booster shot and the fourth dose is six months.
If you have previously received the Sinovac-Coronavac vaccine, you can receive a bivalent vaccine consisting of the Pfizer-BioNTech and Moderna/Spikevax vaccines for your booster shot.
It is important to note that while the Covid-19 vaccines are highly effective in preventing severe illness and hospitalization, they do not provide 100% protection against the virus. It is still important to practice good hygiene and follow safe distancing measures to reduce the risk of infection.
Overall, getting vaccinated and receiving booster shots when recommended is the best way to protect yourself and others from Covid-19.
