The Union Health Ministry on Wednesday dismissed media reports claiming there was dissent from technical experts about increasing the gap between two Covishield doses and said the decision was based on scientific reason about the behaviour of adenovector vaccines.

The Centre on May 13 had approved extending the gap between the two doses of the Covishield vaccine from six to eight weeks to 12 to 16 weeks following a recommendation from the National Technical Advisory Group on Immunisation (NTAGI).
