Extension of gap between two Covishield doses is a decision in right direction: Dr Soin ANI | Updated: May 13, 2021 21:15 IST Gurugram (Haryana) [India], May 13 (ANI): Chairman of Institute of Liver Transplantation and Regenerative Medicine Dr Arvinder Singh Soin on Thursday supported the Union Health Ministry's decision to accept the recommendation of the COVID working group to extend the gap between the first and second doses of Covishield vaccine to 12-16 weeks. Dr Soin said the basic logic is that those who have had one vaccine dose or a previous infection are better protected than those who have had neither of these.
