LONDON – Controversy has erupted over COVID-19 vaccines dosing after the U.K. said it is to prioritize giving as many people as possible a single dose of the two currently approved products, rather than two doses three or four weeks apart, as scheduled on their labels. The move prompted a sharp rebuke from FDA Commissioner Stephen Hahn and Peter Marks, director of FDA’s Center for Biologics Evaluation, who said any such change “is not rooted in the science.”

HONG KONG – India’s conditional approval on Jan. 3 of a COVID-19 vaccine developed domestically by Bharat Biotech International Ltd. but still in phase III trials has sparked concerns about its safety. The Drugs Controller General of India (DCGI) gave emergency authorization to the product, Covaxin, along with the Astrazeneca plc and Oxford University vaccine Covishield. The DCGI said the conditional approval granting “restricted use in emergency situation” for Covaxin was done in “clinical trial mode” to account for the fact that the shot is still being tested. But the rush to approve it has created controversy and confusion.
