Medical data from vaccine use showed that both Sinovac and Pfizer vaccines are equally effective against Covid-19, said Health director-general Tan Sri Dr Noor Hisham Abdullah.

In a Facebook post today, Dr Noor Hisham said on July 7, the New England Journal of Medicine published a report on the Sinovac experience in Chile from February to May 2021 on 4.2 million fully vaccinated individuals compared to 5.5 million unvaccinated residents, with the study also having documented 218,784 Covid-19 cases.

“Sinovac was found to reduce Covid-19 infection by 65.9 percent, reduce hospitalisation by 87.5 percent, reduce intensive care unit (ICU) admission by 90.3 percent and reduce deaths by 86.3 percent,” he said.

Dr Noor Hisham said, in contrast, the Pfizer trial that reported efficacy of 95 percent was very small and analysed only 170 Covid-19 cases involving a group of eight vaccinated and 162 unvaccinated individuals.

Therefore, he said, 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 added.
