Background: Coronavirus disease 2019 (COVID-19) is a highly infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Large-scale vaccination of risk groups and later the general population is the single most effective public health measure for mitigation of the COVID-19 pandemic.

Methods and Materials: This prospective cross sectional study was carried out at Dhaka North City Corporation dedicated COVID-19 hospital, Mohakhali, Dhaka, enrolling 50 (fifty) vaccinated RT-PCR positive COVID-19 patients.

Results: Majority of the patients were >50 years old. Most of the patients had bilateral lung involvement and ground glass was the predominant CT pattern. 20% patients had consolidation in HRCT scan. Most of the patients (46%) had mild disease and only 18% patients had severe disease. Severe cases were more common (77.8%) in older (>50years) patients. 20% of the patients had 50-75% and only 6 % patients had more than 75% of total lung involvement. 52% patients had less than 25% lung involvement. Lung involvement was significantly higher in older patients. Patients had to stay an average of 6.2 days in hospital. Older patients had to stay more days in the hospital than younger patients. 2% (1) of COVID-19 patients died after admitting into our hospital.

Conclusion: Vaccination can effectively reduce mortality and morbidity of COVID-19 patients by reducing the active number of cases as well as severity of the disease.

Keywords: COVID-19, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), vaccination
