and then assessed whether there was an incidence rateinfect and how severely ill between 1 October and 21 November 2021
Among the Singapore population studied, most were injected with Pfizer/Biontech around 2,000,000, Moderna around 600,000, Sinovac/Coronavac around 60,000, and Sinopharm around 20,000.
The results showed that mRNA vaccines (Pfizer/Biontech, Moderna) have a lower incidence of infection.inactivated vaccine (Sinopharm, Sinovac/Coronavac) significantly.
As for the incidence of severe illness, it was found that vaccinated group Sinovac/Coronavac have a higher rate of severe illness than vaccines Pfizer/Biontech 4.59 times (3.25-6.48 confidence intervals), while Sinopharm had the same rate of severe illness as Pfizer/Biontech significantly
However, studying in Singapore indicated that mRNA vaccines appear to be more effective than inactivated vaccines. both in the prevention of infection and the prevention of severe illness
