Increasing gap between 2 vaccine doses could delay protection against Covid-19: AIIMS Doctor

The Covid Working Group chaired by Dr N.K. Arora, on Thursday, recommended extension of the gap between two doses of Covishield vaccine to 12-16 weeks. The Union Ministry of Health and Family Welfare has also accepted this recommendation.

The Serum Institute of India-manufactured vaccine, developed by Astra-Zeneca and the University of Oxford, was initially to be administered 4-6 weeks apart.

However, in April this year, the Ministry of Health and Family Welfare, working on the recommendations of the National Technical Advisory Group on Immunisation and the National Expert Group on Vaccine Administration for Covid revised the interval to 6-8 weeks.
