Abstract:

SARS Co-V-2 has been affecting the entire world since March 2020. Vaccines were introduced both Covaxin and Covishield from January 2021 to protect the individuals. Covishield is a viral vector vaccine using modified chimpanzee adenovirus ChAdOx1and Covaxin is an inactivated virus based Covid-19 vaccine. Though the vaccines were targeted initially to cover health care workers, people above the age of 65 and people above 45 with co morbidities, there was a splurge of second wave in April 2021 which claimed the life of many peoples especially young adults. Keeping this in mind this study has been aimed to assess the severity of illness in vaccinated as well as infected individuals. This study is a knowledge based questionnaire study. Aim and Objective of the study: The objective of the study is to find out the prevalence of infection in infected and vaccinated individuals. Methods: The study was done through knowledge-based questionnaire. Results: Out of 306 participants in the study group we had 148 females (48.4%) and 158 males (51.6%) comprising of 61 (19.9%) health care workers, 43(14.1%) home makers and 201(66%) other professionals. Vaccination history of the study participants of 306 people showed that around 199(65%) people received covisheild, 49 (16%) people received covaxin and 56(19%) people did not receive any vaccine. Out of the 306 participants, 58 (19%) people got infected with SARS Co-V-2. In the infected group 25 (43.1%) got infected after vaccination 31 (53.5%) and 2 (3.4%) got infected both before and after vaccination. So we had only 27 people who had infection after vaccination. Among them, we monitored the severity of infection which showed that 22(37.9%) people required only home isolation, 2 person (3.4%) did not have any symptoms 1 people (1.7%) needed oxygen support and other 2 people needed immediate hospitalization (3.4%). Conclusion: Our study concludes vaccine either covishield or covaxin was effective as the severity of infection following vaccination was very mild which required only home isolation.
