    IntroductionThe first case of novel SARS-COV-2 (COVID-19) in Pakistan was detected on 26 February 2020. Pharmacological and non-pharmacological strategies have been tried to lessen the mortality and morbidity burden. Various vaccines have been approved. The Drug Regulatory Authority of Pakistan gave emergency approval for Sinopharm (BBIBP-CorV) COVID-19 vaccine in December 2021. The phase 3 trial of BBIBP-CorV included only 612 participants aged 60 years and above. The primary aim of this study was to assess the safety and efficacy of BBIBPP-CorV (Sinopharm) vaccine within the Pakistani adult population aged 60 or above. The study was carried out in the Faisalabad district of Pakistan.MethodsA test negative case-control study design was used to assess safety and efficacy of BBIBP-CorV in individuals aged 60 and above against symptomatic infection, hospitalisations and mortality due to SARS-CoV-2 among vaccinated and unvaccinated individuals. ORs were calculated using logistic regression model at 95% CI. ORs were used to calculate the vaccine efficacy (VE) by using the following formula.VE= (1-OR) ×100.Results3426 individuals with symptoms of COVID-19 were PCR tested between 5 May 2021 and 31 July 2021. The results showed that Sinopharm vaccine 14 days after the second dose was efficient in reducing the risk of symptomatic COVID-19 infection, hospitalisations and mortality by 94.3%, 60.5% and 98.6%, respectively, among vaccinated individuals with a significant p value of 0.001.ConclusionOur study showed that BBIBP-CorV vaccine is highly effective in preventing infection, hospitalisations and mortality due to COVID-19.© The Author(s) 2022.
