NEW DELHI, May 28 (Xinhua) -- As many as 30 different groups in India are trying to develop a vaccine for COVID-19, out of which 20 are making fast progress, said Principal Scientific Adviser to Centre Government K. Vijayraghavan on Thursday.
Addressing media persons, the key official who is also the co-chair of the COVID-19 task force on scientific development, however, said none of these groups is in the clinical trial stage for vaccines yet.
"There are about 30 groups in India, big industry to individual academics, are trying to develop a vaccine. Some companies are in the late pre-clinical stage," Vijayraghavan said, adding that the entire process will cost 2 to 3 billion U.S. dollars and the access to the vaccine is a big challenge.
According to media reports, the World Health Organisation (WHO) has listed several Indian firms, including the Serum Institute of India, Zydus Cadila, Indian Immunologicals Limited and Bharat Biotech, among the firms involved in developing a vaccine. Enditem
