Those who are aged between 12 and 17 will be brought under the coverage of vaccination against Covid-19 once it is approved by the World Health Organization (WHO), said Health Minister Zahid Maleque on Monday. “We’ve applied to WHO seeking its approval in this regard. The approval of the National Technical Advisory Committee is also needed. Once approved, we’ll start vaccinating those who are aged 12-17,” said the minister while talking to reporters after a meeting at the secretariat.
