Six Indian companies working for Coronavirus vaccine New Delhi Six Indian companies are working on a Covid-19 vaccine, joining global efforts to curb the spread of the novel coronavirus that’s infected more than 2 million people so far. Nearly 70 "vaccine candidates" are being tested globally and at least three have moved to the human clinical trial stage, but a vaccine is unlikely to be ready for mass use before 2021. While Zydus Cadila is working on two vaccines, Serum Institute, Biological E, Bharat Biotech, Indian Immunologicals, and Mynvax are developing one vaccine each. But it is a complicated process with many stages of testing and many challenges. 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. Phase-Wise Development Vaccine testing typically begins with animals in the lab before going on to different stages of human clinical trials. Phase 2 trials often involve several hundred subjects, and mainly evaluate the efficacy of the vaccine against the disease. The final phase involves thousands of people to further assess the efficacy of the vaccine over a defined period of time, and can last several months. That is why we don’t see a vaccine coming in at least a year from now. According to the World Health Organization, three vaccine candidates are in clinical trial phase, meaning they are able to be tested on humans, while nearly 70 are in the pre-clinical phase—either in lab testing or animal studies.
