Vaccine shortage or science behind change in vaccination policy?

The top focus of this episode of Newstrack is on govt's vaccination policy. Even as people were waiting to get their vaccination, the govt today changed its Covid vaccination policy.

The Centre today approved extending the gap between the two doses of the Covishield vaccine to 12-16 weeks following a recommendation from a government panel, and said it is a "science-based decision" taken with confidence that there will be no extra risk.

So, the big question is this being done because of improvements in vaccine policy or because the govt messed up the old vaccine policy? Watch as panelists share their perspectives on the vaccine policy.
