Vaccination drive in Bangladesh
Bangladesh launched its nationwide Covid-19 vaccination drive on February 7.
By Monday, 4,485,954 people received the first dose of the Oxford-AstraZeneca vaccine. The second dose has to be taken between 8 and 12 weeks of the first one.
The government is providing the vaccine for free. It signed an agreement with India's Serum Institute for acquiring 30 million doses of the vaccine.
The institute will provide five million doses every month between January and June. Those who are 40 or above can register for getting the jab at www.surokkha.gov.bd as the on-spot registration system has been revoked.
Health Minister Zahid Maleque has said the age limit for getting the vaccine will be revised when more doses will be available in the country.
Health authorities attributed the new wave of infections to the P.1 strain that emerged in Brazil's northern state of Amazonas in November last year, and the movement of people during the summer vacation.
India’s total caseload reached 11,359,048 while the death toll from the virus mounted to 158,607.
