The whole world is waiting with bated breath for a ‘safe and effective’ vaccine against novel coronavirus. At present, three vaccine candidates are at different phases of trial in India. Two homegrown vaccine candidates — Covaxin by Bharat Biotech and ZyCoV-D by Zydus Cadila have already started the phase II clinical trial. Another vaccine candidate, Covishield, developed by the University of Oxford has recently commenced the phase II clinical trial in India. Vaccine maker AstraZeneca has signed a deal with Serum Institute of India to manufacture Oxford’s COVID-19 vaccine candidate for India and low-income countries.
When will a COVID-19 vaccine be available in India? Answering to this question Union health and family welfare minister Dr Harsh Vardhan said that a vaccine might be ready by the end of this year.
“We are not lagging behind anyone else in the whole world in our efforts to contribute towards the vaccine against COVID… In India we have about 7-8 vaccine candidates, three of them in the clinical trial phases and rest in the pre- clinical trials and by the end of this year we hope to be able to get a vaccine against COVID,” he said.
