India's Decision To Extend Covishield Dose Gap Reasonable: Dr Fauci

White House's chief medical advisor Dr Anthony Fauci has backed India's decision to extend Covishield dose-gap from 6-8 weeks to 12-16 weeks. Refuting "cover-up" claims for shortage, Fauci called the decision "reasonable" saying, "it is unlikely that long delay would have a negative effect on vaccine efficacy." Earlier, he had also advised India for extensive vaccination and a complete lockdown to contain the second wave of COVID-19.
