On November 22, 2021, Dr. Balram Bhargava said there is no scientific evidence so far to support the need for a booster vaccine dose against COVID-19. The priority was on administering the second dose to all adults. No new evidence from India has become available to support an additional dose after Dr. Bhargava's assertion.

Government passes off factually incorrect vaccination information as ‘fact’

India sets a dangerous precedent with COVID-19 vaccination programme
The unprecedented, hare-brained policy that requires States to buy vaccines, and at a far higher price than what the Central government pays, and framed without consulting the States or giving them prior notice, combined with profiteering by vaccine manufacturers in the thick of the pandemic and vaccine shortage will surely exacerbate vaccine inequity. In the … Continue reading India sets a dangerous precedent with COVID-19 vaccination programme

The Indian regulator should therefore revise the restricted emergency use approval such … Continue reading Covaxin should no longer be available in ‘clinical trial mode’
