NEW DELHI: Amid confusion that the government may completely do away with the second dose of Covid vaccine Covishield, the Centre on Tuesday clarified that there was no change in the existing dosing protocol while also insisting that mixing and matching of vaccines was not a possibility in the near future.
“There is some confusion and misunderstanding but let us make clear that we will keep following the gap interval of 12 weeks between two Covishield doses and everyone will get two doses of both Covishield,” said VK Paul, Member (Health) Niti Aayog and head of the national Covid task force.
