The Bangladeshi government decided on Wednesday to extend the ongoing special campaign to administer the second dose and booster shot of the COVID-19 vaccine by another day to July 21.

As part of the government's all-out efforts to rein in the fresh spike of the pandemic, Bangladeshi health authorities earlier held a day-long countrywide mass vaccination campaign on Tuesday with a view to vaccinating 7.5 million people with the second and booster doses.

More than 285 million doses of the COVID-19 vaccine have so far been administered in the country, and more than half of the administered vaccines were China's Sinopharm.

According to a statement from the government's Management Information System of Directorate General of Health Services (DGHS), a total of 285,882,959 vaccine doses, including 159,514,745 Chinese vaccine doses, had been administered across Bangladesh as of Tuesday.

Bangladesh has been using COVID-19 vaccines developed by AstraZeneca, Sinopharm, Moderna, Pfizer, Sinovac, and Johnson and Johnson.
