The Central Drugs Standard Control Organisation (CDSCO) and Review Committee on Genetic Manipulation (RCGM) recommend the rapid processing of recombinant vaccine development during COVID-19 pandemic under Rapid response Regulatory Framework. All the applications will be screened depending on the proper data and population.
All over the world, scientists are working around the clock to find a vaccine against COVID-19. Global experts estimate that a fast-tracked vaccine can bring a vaccine to market in approximately 12-18 months – if the vaccine development process goes smoothly from conception to market availability.
