India already has at least five vaccine candidates against Covid-19 under human trial, of which three vaccine candidates are undergoing advanced phase 2/3 clinical trials
Union health minister Harsh Vardhan has reiterated that India may not require Pfizer’s vaccine against coronavirus disease (Covid-19), with other vaccine candidates being tested in the country showing promising results in safety trials so far.
According to media reports, the health minister said that it did not make sense to consider the Pfizer-BioNTech’s vaccine as even the US regulatory authority had not yet granted approval to the vaccine. And even if the approvals are granted, the manufacturer would first attempt to cater to its local population before supplying the vaccine to other countries, he said.
India has at least five vaccine candidates against Covid-19 under human trial, of which three vaccine candidates are undergoing advanced phase 2/3 clinical trials to establish safety and efficacy.
The Serum Institute of India is conducting the phase 3 trial with the Indian Council of Medical Research (ICMR) for the Oxford-AstraZeneca vaccine candidate.
The Bharat Biotech-ICMR vaccine candidate, Covaxin, has also progressed, and phase 3 trial has started. The results of its phase 2 trials are expected anytime now.
Cadila Health’s vaccine candidate, ZyCovD, has also completed the phase 2 trial, and is awaiting results, even as the follow-up period is nearing its end.
Apart from these three, phase 2/3 trials for the Sputnik V Russian vaccine, for which India’s Dr Reddy’s labs has tied up with the Russian vaccine developers, is going to start anytime this week.
