Abstract
Introduction: The objective of this study was to analyse the effectiveness of the COVISHIELD vaccine among the interns working in the Acharya Vinoba Bhave rural hospital (tertiary care hospital of central India).
Methods: We surveyed 71 M.B.B.S interns over the period of 1 month. Selected healthcare workers were invited to participate in the online survey. A pre-constructed, confidential, validated, self-administered online survey questionnaire inquiring about the history of COVID-19 and COVISHIELD vaccination was provided to selected interns. Online survey was based on the retrospective study with the questions related to the past medical history, COVID-19 infections in the past, vaccination history, symptoms during COVID-19 positive period, and presence of radiological evidence suggesting COVID-19 infection affecting the lungs. The prime question to calculate the analysis of this study was "Have you tested positive any time after taking 1st dose of COVISHIELD?
Results: According to survey analysis effectiveness of the COVISHIELD vaccine in interns working in AVBRH is found out to be 94.37 % after taking both doses of COVISHIELD vaccine. The most common symptoms were fever (13.33%), weakness/ fatigue (12.22%), cough (12.22%), and loss of taste (10%).
Conclusion: The study indicates that the COVISHIELD vaccine is found out to be highly effective in preventing COVID-19 infection among interns. However, this evidence should be further assessed in larger trials.
