A Retrospective Study of Mortality Benefit Provided by Single Dose COVID Vaccine at Society Level During Second Wave of COVID at A Zonal Hospital

Since December 2019, the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) pandemic has caused high morbidity and mortality, with new variants rapidly spreading. Vaccines to prevent corona virus disease 2019 (Covid-19) have been developed with unprecedented speed. An open, real-time, retrospective observational study was conducted at 167 Military Hospital, Pathankot. Data was available for 490 Covid 19 patients. The population of interest was 18-87 years old patients who were treated for moderate to severe covid pneumonia irrespective of the vaccination status. Vaccination history was documented on admission. We also documented awareness regarding the name of covid-19 vaccine administered to the patients admitted in this hospital. Between 08 Dec 2020, and 20 Jun 2021, 490 patients aged 18 years and older were treated for moderate to severe covid pneumonia. Out of these 490 patients, 132 patients had received first dose of covid-19 vaccine 14 days prior to onset of symptoms. Mortality happened in 55 patients out of which seven patients had received vaccine (p<0.05). Overall, there is very poor awareness regarding the type of covid-19 vaccine being administered to the patients
