Sinopharm Covid-19 vaccines appear safe, effective, says study
JAKARTA: Two vaccines made by Sinopharm from China appear to be safe and effective against COVID-19, according to a study published in a medical journal.
Scientists had been waiting for more details on the two vaccines, even though they are already in use in many countries, and one recently received support from the World Health Organization for emergency use.
The report, published online in the Journal of the American Medical Association, concluded that the two vaccines are about 73 percent and 78 percent effective, as Sinopharm previously claimed.
Researchers from Sinopharm and its local Middle East partners say the trial involved approximately 40,380 participants with the company's two vaccines – one developed by the Wuhan Institute of Biological Products and the other by the Beijing Institute of Biological Products – and a placebo.
The trial was conducted in four countries: Bahrain, the United Arab Emirates, Egypt and Jordan. However, the study only provided data for Bahrain and UAE.
& # 39; There is nothing very surprising. It is in line with what they previously claimed, but it does not completely dispel doubts about Sinopharm, ”said Jin Dong-yan, a medical professor at the University of Hong Kong who was not involved in the study.
He expressed doubts about how protective the vaccine was, based on a recent wave of cases in the island state of Seychelles that had a large majority of its population vaccinated with the Sinopharm vaccine.
The study, which was conducted mainly in younger men, had little information about the vaccine's effectiveness against serious illness. Some experts also expressed concern about the shortage of female participants, nearly 85 percent of whom are male.
"It's important to make sure you've tested it on enough women to see potential safety concerns," said Ashley St. John, associate professor at Duke-NUS Medical School in Singapore.
A company spokesperson did not immediately respond to a request for comment.
The vaccines, both of which are made with inactivated viruses, have already been given to millions of people around the world.
The World Health Organization approved the inclusion of the Beijing Institute of Biological Products for emergency use in early May, making it the first Chinese vaccine to receive certification.
Chinese Foreign Minister Wang Yi said in April that China has supplied vaccines to more than 100 countries, although it has not identified them. While China has six vaccines in use, most of its exports come from two companies: Sinopharm and Sinovac.
