A comprehensive policy on additional Covid vaccine doses for immunocompromised people will be drawn up over the next two weeks, Dr NK Arora, chairman of the country's Covid Task Force, has told NDTV. The policy will be formulated by the National Technical Advisory Group on Immunisation -- along with another one on vaccinating the country's 44 crore children. The prioritisation process is in progress, so children with comorbidities are given the vaccine first, he said.
