Two Chinese pharmaceutical companies will provide 110 million vaccine doses for the coronavirus disease 2019 (Covid-19) immediately to participants of the COVAX project, announced the global Vaccine Alliance Gavi on Monday.
The Chinese Sinopharm and Sinovac vaccines have been approved earlier this year by the World Health Organization (WHO) for emergency use.
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.
China’s CoronaVac 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.
In London, interim analysis of Phase 3 clinical trial of the CoronaVac vaccine in more than 10,000 participants in Turkey suggests the efficacy of two doses of the vaccine is 83.5 percent against symptomatic cases of Covd-19, according to a study published in The Lancet, a weekly peer-reviewed general medical journal.
In Thailand, a vaccination study conducted by Thailand’s Chulalongkorn University has found that China’s Sinovac vaccine has extremely high efficacy in boosting immune responses against Covid-19, according to media reports.
The study run by the Center of Excellence in Clinical Virology of the Faculty of Medicine at the university showed that 99.49 percent of the recipients had developed antibody responses four weeks after their second shots, the Bangkok Post said, quoting the study results.In Argentina, the Covid-19 vaccine developed by Chinese pharmaceutical company Sinopharm is 84 percent effective in preventing death from the disease, showed a report by the Argentine Ministry of Health.
