Bangladesh will receive a minimum of 1,06,000 doses of Pfizer vaccine by June 2, Health Minister Zahid Maleque said Tuesday.

The doses will be sent to Bangladesh under the COVAX scheme which is co-led by Gavi, the Coalition for Epidemic Preparedness Innovations (CEPI), UNICEF and the World Health Organization (WHO), said Maidul Islam, the public relation officer of the ministry.

The Pfizer BioNTech vaccine has an efficacy of 95% against symptomatic SARS-CoV-2 infection.

However, preliminary laboratory studies of the mRNA vaccines by Pfizer and Moderna have shown decreased effectiveness against the double mutant variants discovered in India, WHO said in a note.
