Abstract

Abstract Background: Vaccination against severe acute respiratory syndrome coronavirus 2 is a pivotal step in stopping the global pandemic. Knowledge regarding the relationship of vaccination status among comorbid COVID-19 patients would definitely provide more information. Objectives: The objective was to study the proportion of vaccination status among COVID-19 patients admitted in a tertiary medical college at Calicut district and to study the association of vaccination status with independent risk factors among COVID-19 patients admitted in a tertiary medical college at Calicut district, Kerala. Materials and Methods: A cross-sectional study was done among COVID-19 patients admitted to a tertiary medical college. The sample size calculated was 202 and the sampling technique used was consecutive sampling. The data analysis was done using SPSS version 16.0. Results: In this study, the proportion of vaccination status among admitted COVID-19 patients was 65.8%. Sociodemographic variables comprising age, gender, religion, education, occupation, and per capita income were tested for association with the dependent variable. To socioeconomic classification, the upper middle-class group was associated with high vaccination status compared to other groups and the results were statistically significant. The relationship between vaccination status and comorbidities was tested and it found those patients who had no prior exposure to COVID-19 on anticoagulant therapy compared to the prior exposure group to anticoagulant therapy were associated with high vaccination status and the results were statistically significant. Conclusion and Recommendation: The present study shows that only 65% had taken COVID-19 vaccines previously. There should be further studies to know the reasons for barriers to the COVID-19 vaccination program.
