Like many things in India nowadays, the science of vaccine approval has also run into the politics of chest-thumping nationalism. Alongside authorizing Covishield, the Covid-19 protection developed by Oxford University and AstraZeneca Plc and manufactured by the Serum Institute of India Ltd., the country’s drugs regulator on Sunday gave a go-ahead to an indigenous vaccine for which critical phase three trial data isn’t available. The hasty nod for Bharat Biotech International Ltd.’s Covaxin, developed in collaboration with the Indian Council of Medical Research and National Institute of Virology, has raised eyebrows in the scientific and healthcare communities about a “public rollout of an untested product,” according to a national network of nongovernment organizations. This is unfortunate. With more than 10 million coronavirus infections, India is the world’s second-worst-affected nation after the U.S. New Delhi’s strategy for vaccinating 1.3 billion people will matter greatly for bringing the global pandemic to a decisive end. The country’s virus-battered economy and its overstretched health systems are also yearning for a reprieve. It will be dangerous to allow political calculations to enter the equation and shake people’s confidence in what’s being offered to them — and on what basis. That’s just what seems to be happening with the unusual approval for Covaxin, which comes with the odd caveat that its use will be restricted to “public interest as an abundant precaution, in clinical trial mode, especially in the context of mutant strains.” Nobody seems to know what this will mean on the ground. Who’ll get Covishield, and who’ll be given Covaxin? More importantly, who’ll decide? In a country beset by massive inequalities in income, wealth and social status, these aren’t trivial questions. When opposition leaders raised doubts about the vaccine selection process, a minister in Prime Minister Narendra Modi’s cabinet likened their objections to questioning “the valor of our soldiers.” The Indian Council of Medical Research was pushing Bharat Biotech to launch Covaxin by Aug. 15, India’s independence day. Thankfully, that deadline came and went. But the impatience we saw back then is once again rearing its head when the message for India should be the exact opposite. Properly designed and implemented studies, honestly reported side effects, and transparently shared efficacy data.
