As the ruthless Delta variant of Covid-19 keeps spreading like wildfire, Bangladesh on Saturday kicked off another phase of its mass vaccination drive aimed at inoculating 35 lakh people in six days. Covid jabs will be administered simultaneously in 4,600 unions, 1,054 municipality areas and 433 wards of the city corporations, Director General of Health Services Dr ABM Khurshid Alam told the media on Friday. With a fresh stock of Covid-19 vaccine doses in hand, the government’s aim is to inoculate 80% of its population, with each getting two doses administered. Some 32,706 vaccinators and 48,459 volunteers have been roped in to make the vaccine drive a success. Those above 25 years of age will be vaccinated, but priority would be given to the elderly, the women and physically-challenged persons, said Dr Khurshid.
