Written Answer

Members are interested to know how different COVID-19 vaccines compare in terms of their protection. As we roll out our vaccination and booster programmes, MOH and HSA have continued to collate and analyse data on the effectiveness and safety for different vaccines. The following are what we have found out so far.

First, there is a big difference between being vaccinated and not vaccinated. Between 1 May 2021 to 30 September 2021, the COVID-19 mortality rate was 7.5 per million persons among those vaccinated with the two mRNA vaccines. In contrast, the mortality rate among those who were unvaccinated or partially vaccinated was 92 per million persons. In the same period, the risk of severe disease, including the need for intensive care and/or oxygen supplementation, was 86 per million persons for those vaccinated with the two mRNA vaccines, and around 530 per million persons for those who were unvaccinated or partially vaccinated.

Second, both mRNA vaccines in our National Vaccination Programme work very well. Both mRNA vaccines protected infected persons against severe disease by around 90%. The mRNA vaccines also reduced the risk of infection by around 40% and halved the risk of onward transmission.

However, a comparison with the non-mRNA vaccines cannot be made at this time, as the number of persons vaccinated with them is much smaller. Less than 2% of the population was fully vaccinated with Sinovac-CoronaVac as of 30 September 2021. Further, in Singapore, a very small proportion of seniors aged 60 years and above chose to be vaccinated with Sinovac-CoronaVac, as the take-up has been mostly in younger people. In a recent study in Chile, Sinovac-CoronaVac was found to confer 58% protection against symptomatic infection compared to 88% for Pfizer. The corresponding figures for protection against severe illness requiring ICU care were 90% and 98% respectively.

Current evidence shows that persons vaccinated and boosted with the PSAR-authorised mRNA vaccines develop the strongest boosting in antibody levels and protection against infection and severe disease, compared to other COVID-19 vaccines.

The Health Sciences Authority (HSA) closely monitors the safety of the COVID-19 vaccines. As of 18 October 2021, the rates of reported Severe Adverse Events for Sinovac-CoronaVac and the mRNA vaccines were similar, at around 0.005%. Management of adverse events from vaccines, as with other conditions, is evidence-based and takes into consideration local and international data as well as the patient’s medical condition.
