PUTRAJAYA JULY 20: The vaccine produced by Sinovac and Pfizer-BioNTech are equally effective in preventing severe COVID-19 infections.Director General of Health, Tan Sri Dr. Noor Hisham Abdullah said, there is a good published medical data on the actual effectiveness of Sinovac used in the real world setting.
Dr. Noor Hisham said, on 7th July 2021, the New England Journal of Medicine published a report on the Sinovac experience in Chile from February to May 2021 looking at 4.2 million fully vaccinated people compared to 5.5 million unvaccinated residents.
Citing the New England Journal of Medicine, Dr. Noor Hisham said: “Sinovac was found to reduce COVID-19 infection by 65.9 per cent, reduce hospitalisation by 87.5 per cent, reduce Intensive Care Unit (ICU) admission by 90.3 per cent and reduce deaths by 86.3 per cent.”
“In contrast to this article from Chile that had 218,784 COVID-cases, the Pfizer trial that reported an efficacy of 95 per cent was very small and analysed only 170 COVID-19 cases, eight in vaccinated and 162 in unvaccinated group,” Dr. Noor Hisham said in his Facebook here today.
Meanwhile, the Israel Ministry of Health has also pointed out recently that the effectiveness of the Pfizer vaccine against Covid-19 infection was 64%, although it was still 93% effective against hospitalization and serious illness (Israel sees drop in Pfizer vaccine protection against infections, still strong in severe illness.)
Dr. Noor Hisham added, there is not much difference between the Sinovac and Pfizer vaccines in actual practical use. Both are very effective at preventing severe disease and hospitalization, but less effective against mild or asymptomatic COVID-19. – Malaysia World News.
