COVID-19: Should the gap between vaccine doses be increased?


Global studies suggest increasing gap between doses


'20-30% greater efficacy achieved by stretching gap'

Scientific evidence from across the globe shows that there is 20-30% greater efficacy by stretching the interval between two doses, vaccine scientist Dr. Gagandeep Kang told The Indian Express. "So why would we not want to do that?"


Increasing gap can help more people receive jabs


But can the first dose provide enough protection?

The first dose of Covishield can provide 76% protection for the three months between the doses, The Lancet study finds. "There is ample evidence from the Lancet paper that one gets pretty good short-term protection from the first dose," Dr. Kang told the publication.


SII scientists also support the suggestion


However, some experts advise caution
