Initially, the gap between two doses of Covishield was four to six weeks but then as more data became available, analysis showed increasing the dosage interval to four to eight weeks can have some advantage.

The decision regarding enhancing interval between two doses of Covishield was based on scientific evidence and taken in a transparent manner, NTAGI Chair N K Arora said on Tuesday. There was no dissenting voice among the members of the National Technical Advisory Group on Immunization (NTAGI), he said, according to a tweet by the Union health ministry. The government had on May 13 said it has accepted the Covid-19 Working Group's recommendation and extended the gap between the two doses of the Covishield vaccine from 6-8 weeks to 12-16 weeks.
