New Delhi | The Covid-19 Working Group of the National Technical Advisory Group on Immunisation (NTAGI) discussed the inclusion of Covovax vaccine as a heterologous booster dose for adults on the CoWin portal to boost the uptake of precaution doses, official sources said on Saturday.

A final decision on its inclusion will be taken by the NTAGI's Standing Technical Sub-Committee (STSC) which is likely to meet by the end of this month.
