    Please consult our doctors if you are unsure about getting the vaccine. You may also refer to this MOH link for more information:

  3. For Primary Series Vaccination – Ministry of Health Singapore recommends that persons who receive Sinopharm are advised to receive a three doses vaccine as primary series.  WHO recommends an interval of 3–4 weeks for the 2nd dose. The third dose should be taken 90 days after the second dose.
  4. Persons who receive Sinopharm will only be considered fully vaccinated after completing the 3-dose primary series.

MOH maintains recommendations

  • Booster vaccine is recommended to be administered 3 months after a primary course of inactivated vaccine or after recovery from COVID-19 infection.

How does Sinopharm vaccine work?

Sinopharm vaccine exposed the body to inactivated COVID-19 virus, to induce the immune system will make antibodies against the coronavirus, attaching to viral proteins. The delivery virus has been attenuated so you won’t develop the common cold when administered with this vaccine.  Your body immune system can then respond to an infection of live coronaviruses by producing antibodies to block the virus.

Why is it important to get the COVID-19 vaccine?

The Singapore government has advised that COVID-19 vaccination will help to protect us and our loved ones against COVID-19. Vaccination will not only reduce the number of people susceptible to the coronavirus, but also reduce the chances of transmission in the community.  A high local vaccination coverage is key to protect ourselves from COVID-19, and we encourage all medically eligible persons to be vaccinated.

How effective is the Sinopharm vaccine?

The Sinopharm vaccine’s efficacy rate is currently at 79% in preventing symptomatic infection in the multi-country Phase 3 trial. This can be compared to 51% for the Sinovac vaccine and 95% for the Pfizer-BioNTech/Cominarty vaccine.  More studies are required to determine COVID-19 vaccine efficacy against COVID-19 variants.

HSA safety update #6 (30 December 2020 – 30 September 2021) – Incidence of Adverse Effects (AE)

  • Sinopharm 0.02% AE (none serious)
  • Sinovac 0.06% AE (0.005% serious)
  • mRNA 0.14% AE (0.006% serious), 81 local cases of myocarditis, pericarditis, 8.4 per 100,000 cerebral venous thrombosis.

Do you need a booster vaccine?

There has been evidence that antibody levels from COVID-19 vaccines decline with time after the primary series.  Booster vaccine increases this antibody response substantially.
