There are several rumours out there that promotes one vaccine over another. However, those claims that are circulating around the Internet are not based on any reliable studies nor supported by statistics.

On Tuesday (20 July), the Health director-general, Tan Sri Dr Noor Hisham Abdullah took it to his Facebook to clarify that the vaccines produced by Sinovac and Pfizer are both equally effective in providing protection against severe Covid-19 infections.

He added that the claim is supported by medical data in real-world, where both vaccines show similar efficacy rates against the virus.

He then cited a report published by the New England Journal of Medicine on 7 July which detailed the use of Sinovac vaccine in Chile from February to May 2021.

The study took into consideration the 4.2 million of the citizens who were given the Sinovac vaccine compared to the 5.5 million of unvaccinated citizens, as well as having documented 218,784 Covid-19 cases.

“Sinovac was found to reduce Covid-19 infection by 65.9%, reduce hospitalisation by 87.5%, reduce ICU admissions by 90.3% and reduce deaths by 86.3%.” he said.

While comparing Sinovac to Pfizer, Noor Hisham said that the Pfizer trial which reported an efficacy of 95% was conducted on a very small and analysed only 170 Covid-19 cases, where among the 170 participants, only 8 were vaccinated and the remaining 162 unvaccinated.

Noor Hisham added that the Israel’s Ministry of Health pointed out that the effectiveness of the Pfizer-BioNTech vaccine had fell to 64% since 6 June. Nonetheless, it is still 93% effective in providing protection against severe infection that led to hospitalisation and serious illness.

“Therefore, there is not much difference between the Sinovac and Pfizer vaccines in actual practical use. Both are very effective at preventing severe disease and hospitalisation, but less effective against mild or asymptomatic Covid-19.” he said.

Having that said, all vaccines are good vaccines as long as it provides you protection against severe infections.
