The vaccination drive for all above 18 years in Punjab may get delayed as the state does not have enough doses of the anti-coronavirus vaccine, its Health Minister Balbir Singh Sidhu said on Thursday. The inoculation drive for those between 18 and 45 years of age was scheduled to start from May 1. "We are not getting adequate doses of vaccines. That is why we are facing problems. We have staff and required infrastructure for vaccination," Sidhu said addressing the media here.
