The World Health Organization (WHO) is soon going to take an important decision on emergency approval for Bharat Biotech's Kovid-19 vaccine Covaxin. The organization's principal scientist Soumya Swaminathan said that approval for the use of the vaccine will be given in the next 4-6 weeks.
In a webinar organized by CSE on Friday, Swaminathan said that Bharat Biotech is now uploading the complete data of the vaccine on the portal, which is being reviewed by the WHO. According to WHO guidelines, the EUL process allows for the use of new or unlicensed products for use in emergency situations involving health.
Swaminathan said, 'EUL has to go through a process and to get the approval of the vaccine, the company has to submit the data of three phase trials which are examined by experts under WHO and then approved.' At present, Corona Vaccine Pfizer/BioNtech, AstraZeneca-SK Bio/Serum Institute of India, AstraZeneca EU, Janssen, Moderna and Sinopharm have been approved for emergency use by WHO.
The WHO scientist also said that the delta variant of the coronavirus is quite contagious. He said, 'Two doses of the vaccine are necessary to protect against the delta variant but even then you can get infected and spread it. Therefore, masks and other precautions will have to be continued. He also referred to companies insisting on the need for booster doses after two doses of the vaccine. He said that the booster dose is not needed right now and it will be needed after a year or two. Describing the vaccination campaign as satisfactory, he said, "Immune response has been seen to be intact for 8, 10, or 12 months in those who have taken the vaccine.
