Government health facilities, which are more popular and have more capacity, have been seen to attract more people wishing to get immunized.
But other specialized hospitals and lesser known government facilities are still serving below their capacity.
The number of vaccine recipients also increased across the country, with 158,451 more getting vaccinated on Wednesday, while 70 experienced common side effects.
With the latest development, the number of people vaccinated rose to 337,769, with altogether 277 people reporting common side effects.
According to data provided by Directorate General of Health Services (DGHS), over 950,000 people have registered for the Oxford-AstraZeneca vaccine as of now.
On a visit to the National Institute of Cardiovascular Diseases (NICVD), it was found that five teams of health professionals were administering vaccines but there was no crowd waiting to get registered manually.
However, at Shaheed Suhrawardy Medical College and Hospital (ShSMCH), one of the well-known hospitals of the capital, there were a large number of aspirants as people from Mohammadpur and other adjacent areas went there to get registered for vaccine jabs.
One of them was Mohammad Siraj, a rickshaw puller, who had been waiting there for over one hour for his turn for on-the-spot registration.
He chose the hospital as he and his family members had received treatment from there before. “I know this hospital well. Where else would I go?” he told this newspaper.
Substantial crowds were also seen at the capital's Sir Salimullah Medical College and Mitford Hospital, Mugda Medical College and Hospital and Mahanagar General Hospital.
When contacted on Wednesday noon, Bangabandhu Sheikh Mujib Medical University (BSMMU) Vice Chancellor (VC) Prof Kanak Kanti Barua said: "As the number of people wanting to get vaccinated is increasing we have set a target to immunize 3,000 people today [Wednesday]."
However, the hospital was able to provide doses to some 1,837 people by the end of the day.
It is to be noted that the hospital had a target of vaccinating 1,000 people on Tuesday but ended up immunizing a total of 1,494.
A similar trend was reported from outside Dhaka as well.
Khulna Civil Surgeon Dr Niaz Morshed said: “With the increasing interest shown by people, we are now convinced that we will soon complete our quota of vaccinating 84,000 people.”
Chittagong Civil Surgeon Dr Sheikh Fazle Rabbi said out of the 15 vaccination centres in Chittagong city, people favoured Chittagong Medical College Hospital (CMCH) more than others.
Speaking to Dhaka Tribune, Brig Gen SM Humayun Kabir, director of CMCH, said that starting with only four booths now the hospital had 10 booths to cope with the increasing crowd.
Dr Hasan Shahriar Kabir, Chittagong DGHS divisional director, said: “To streamline the vaccination drive, we are considering increasing the number of booths."
Deputy Director of Rajshahi Medical College Hospital Saiful Ferdous said that there were two centres in the city at the moment and the number of vaccine seekers would go up in the coming days.
"To carry out their vaccine efforts more efficiently, two more teams were deployed by Rajshahi City Corporation on Tuesday," said RMCH sources.
