WHAT IS THE DIFFERENCE BETWEEN THE VACCINES?
Both Pfizer-BioNTech and Moderna make use of mRNA technology.
Pfizer-BioNTech has an efficacy rate of 95 per cent, while for Moderna, it is 94 per cent. Both are offered for free to all Singaporeans and long-term residents here.
Here is how they compare to other vaccines on the EUL.
Inactivated vaccines: This is traditional vaccine technology that uses inactivated coronavirus to trigger an immune response. This is a similar method vaccines for diseases such as polio use.
Sinopharm has an efficacy rate of 79 per cent, while Sinovac’s is 51 per cent.
Viral vectors: This vaccine type uses a modified version of a different virus (the vector) to deliver important instructions to human cells to elicit an immune response from vaccinated individuals.
Oxford-AstraZeneca has an efficacy rate of 63 per cent, while Johnson & Johnson’s is 66 per cent.
ARE NON-MRNA VACCINES SAFER?
Professor Dale Fisher, a senior infectious disease consultant at the National University Hospital, said that mRNA vaccines have “come through as a stellar platform” during the pandemic due to their high efficacy rate.
That said, infectious disease specialist Leong Hoe Nam noted that Singapore was previously adopting a “one-size-fits-all for everyone” by only allowing the use of Pfizer-BioNTech and Moderna vaccines.
“But it doesn't work that way,” he said. “For some individuals, you need an alternative vaccine, such as those with multiple allergies.”
Professor Paul Tambyah, president of the Asia Pacific Society of Clinical Microbiology and Infection, said that the rates of anaphylaxis reported with the viral vector vaccines and the inactivated vaccines are reportedly lower than with the mRNA vaccines.
