VACCINE FOR COVID19 (Part III)
Six Indian companies are working on coronavirus vaccine. A vaccine for coronavirus is unlikely to be ready for mass use before 2021, says a top Indian scientist.
" While Zydus Cadila is working on two vaccines, Serum Institute, Biological E, Bharat Biotech, Indian Immunologicals and Mynvax are developing one vaccine each," Gagandeep Kang, executive director of the Translational Health Science and Technology Institute, Faridabad, told PTI. But it is a complicated process with many stages of testing and many challenges, explained experts. A vaccine for the new coronavirus, SARS-CoV-2, may not take 10 years that other vaccines do but it could be at least a year before it is proven safe, effective, and made widely available, they said.
"Vaccine development is a lengthy process which often takes years, with many challenges," said E Sreekumar, chief scientific officer at the Rajiv Gandhi Centre for Biotechnology in Kerala. "The human testing phase is composed of many phases." Sreekumar told PTI. "Phase one trials are small scale, usually involving few participants, to assess whether the vaccine is safe for humans. Phase II trial often involves several hundred subjects, and mainly evaluate the efficacy of the vaccine against the disease," he said.
