BEIJING. KAZINFORM China is the world's largest vaccine supplier, having supplied more than 480 million doses of COVID-19 vaccines to the international community, provided vaccine assistance to nearly 100 countries, and exported vaccines to more than 50 countries.
With Chinese vaccines being administered worldwide, they have been found, according to multiple studies, highly effective in preventing infection, hospitalization, severe illness and death from the virus, Xinhua reports.
SANTIAGO -- China's CoronaVac COVID-19 vaccine effectively prevented COVID-19 in Chile, with the adjusted vaccine effectiveness reaching 90.3 percent for the prevention of severe disease, according to a study recently published in the New England Journal of Medicine.
A nationwide mass vaccination campaign was conducted from Feb. 2 to May 1, and a cohort including approximately 10.2 million people aged 16 years and above was used, according to the study titled Effectiveness of an Inactivated SARS-CoV-2 Vaccine in Chile published.
Among those who were fully immunized, the adjusted vaccine effectiveness was 65.9 percent for the prevention of COVID-19, 87.5 percent for the prevention of hospitalization, and 86.3 percent for the prevention of COVID-19-related death, the results of the study showed.
The CoronaVac, also known as the Sinovac COVID-19 vaccine, is an inactivated virus COVID-19 vaccine developed by Chinese pharmaceutical company Sinovac Biotech.
CoronaVac uses an inactivated whole virus, compelling a recipient's immune system to attack the harmless form of the virus by producing antibodies to fight it off, thus leading to immunity.
