PUNE: Three vaccines against Covid-19 — Covovax, Corbevax and ZyCov-D — which received the Drug Controller General of India’s nod last year for emergency use in the country are yet to be used in the immunisation drive, raising questions on the delay in their utilisation. While Zydus Cadila’s ZyCoV-D was granted emergency use authorisation on August 20 last year, the authorisation was given to Serum Institute’s Covovax on December 28 and to Biologocal E’s Corbevax on December 29.
Experts claimed that this was the right time to expedite the rollout of the approved vaccines because the government had started the vaccination of adolescents and precautionary doses were being administered to the vulnerable population and frontline workers. A leading public health expert though said the three vaccines’ manufacturers would have to ensure enough supplies before the rollout was announced.
