If things go according to plan, the vaccine would be available in the market by the end of this year.
On Tuesday, Rao said there was a possibility of the PM's visit to Pune, and if that happens, it would be aimed at reviewing the status of the vaccine candidate for coronavirus infection and to know about its launch, production and distribution mechanisms.
The teams were from Gennova Biopharmaceuticals Ltd Pune, Biological E Ltd Hyderabad and Dr Reddys Laboratories Ltd Hyderabad.
Responding to another question, Choubey said that the phase-I of clinical trials have revealed excellent safety of the two candidate vaccines indigenously developed by Bharat Biotech in collaboration with Indian Council of Medical Research and Cadila Healthcare Ltd, and now their immunogenicity testing is in progress. Their phase II clinical trials are ongoing.
The aim of the mission is to accelerate the development of at least six vaccine candidates and ensure that they are licenced and introduced in market for emergency use at the earliest.
To address the shortage of COVID-19 jabs in the country, the government is exploring the possibility of boosting production of vaccines, including identifying manufacturing sites for indigenously developed Covaxin outside India, sources said.
While Covishield supplies would meet the target of 500 mn doses between August and December, it looks like Covaxin would miss the target of 400 mn unless the partner sites of Bharat Biotech ramp up very rapidly, reports Sohini Das.
