The expert committee nominated by the Central Drugs Standard Control Organisation (CDSCO) has recommended the use of the Oxford University/AstraZeneca vaccine AZD1222 for emergency use in this country. Given AstraZeneca’s decision to license the vaccine to Pune-based Serum Institute of India (SII), this shot will be a primary component of the programme in India. Other vaccines in SII’s stable include the one developed by the US-based company Novavax, of which the Duke University Global Health Innovation Centre reports it will produce one billion doses, alongside 500 million of AZD1222. Novavax began Phase III trials in the UK in November and has begun them in the US and Mexico in the past few days, and the Indian regulator has sought further information before permitting a bridging trial here that could speed up approval. Being behind on the timeline is problematic; as more and more trials are conducted alongside effective vaccines already being developed, the trials will slow as there are fewer volunteers available. Indeed, the other vaccine given permission for “restricted use in emergency situation in the public interest as an abundant precaution”, from Bharat Biotech, does not seem to have even completed its Phase III trials as yet. The logic of rushing ahead with this approval is, therefore, unclear, given no other regulator has seen the data, no trials elsewhere have been completed — and preparation to roll out the vaccine is itself running late.
