Bangladesh has so far received 38,913,730 vaccine doses from different global sources and administered 27,235,548 shots in the past eight months, covering only 7.0 per cent of the target.
The government has a target to administer 117,856,000 people with two doses, meaning that the country needs 23.4-million jabs.
According to health ministry statistics, Chinese Sinopharm vaccine tops the list in vaccination as 12,299,323 doses of this vaccine are administered.
With 11,394,499 doses in volume, AstraZeneca stands second followed by Moderna with 15,742,065 doses and Pfizer with 98,984 doses.
Meanwhile, health minister Zahid Maleque on Saturday said the government was planning to buy 160-million doses of vaccine.
China would supply 60-million doses within three months, signalling 20-million doses each month, he said, adding: "This is additional to 10.5 million shots for which a deal was signed earlier."
The government will also procure 105 million from the World Health Organisation, the minister says as there are more supplies from other sources.
At the latest, Bangladesh got 1.0-million Pfizer vaccines from the US under Covax facility last week and is expecting another 5.0 million soon.
The country started the mass vaccination drive on February 07.
But it is unlikely to get Sputnik vaccine from Russia soon as announced by health ministry earlier.
The government has a plan to procure more than 1.0-million doses of the vaccine from Russia.
"Third wave is ongoing in Russia that needs more vaccines now. We were in talks with them for a procurement deal and they were very positive," a senior official of the ministry said preferring anonymity.
"But now it seems they are not in a position to supply us vaccine soon," he added.
Earlier, foreign minister Dr AK Abdul Momen said the Russian officials, who were concerned about the vaccine deal, were not responding as they were in lockdown.
"We have sent all the papers regarding the deal but we are yet to get any response as the officials concerned are not going to office due to Covid lockdown."
Despite the delay, officials say, the supply situation is improving.
The vaccination campaign in the country faces a setback due to supply constraints since the beginning.
The government ceased administering the first doze of AstraZeneca and Moderna vaccines as supplies halted.
Administering AstraZeneca resumed lately after a long gap with a 3.0-million fresh stock sent by Japan under the Covax facility.
The 1.5-million people, who were deprived of the second dose after a halt in supply by Serum Institute of India, are being administered from the Japanese stock.
