A BSTRACT Objectives: The aim of this study was to determine the adverse events following immunisation (AEFI) in various age groups after coronavirus disease 2019 (COVID-19) vaccination and assess the association of comorbidities with AEFI. Methods: An observational analytical study was conducted among the general population who had received both doses of the COVID-19 vaccine. A total of 389 participants from the 18–44 years age group, 380 participants from the 45–60 years age group and 373 participants from the 60 plus age group were enrolled in the study after verbal and written consent. Simple random sampling was used to select the study participant in each group. Home visits were made to fill out the semi-structured questionnaire for information regarding any adverse event following COVID-19 immunisation. Results: Overall, 31.9%, 19.74% and 15.17% of >60, 45–60 and 18–44 years, respectively, reported any AEFI after COVID-19 immunisation. The severity of AEFI was more among the 18–44 years age group (66.1%) followed by 45–60 years (30.67%) and less among the older one, that is, >60 years. Fever and pain with inflammation at the injection site were the most common AEFI reported after any dose. There was no association of comorbidity with the severity of AEFI. Conclusion: Since the AEFI reported are very less, most of them were of a minor type and were general immunogenic reactions of any vaccine. Hence the COVID-19 vaccines are very safe, and uptake should be high among all the recommended age groups to combat the severity of the COVID-19 disease.

Introduction: For curbing Covid-19 disease, adequate knowledge, attitude, and practices of both rural and urban population for Covid-19 disease prevention is required along with busting of the associated myths. Objectives: To assess the Knowledge, Attitude and Practices of urban and rural residents of Lucknow district regarding covid-19 preventive behaviour and associated myths. Methodology: A community-based study was conducted among 420 rural and 421 urban residents of Lucknow. Multistage random sampling was done to select the study subjects. A pre-designed pretested semi-structured questionnaire was used to collect the information regarding the Knowledge, Attitude and Practices of the residents for covid-19 disease causes, prevention, and treatment. Further, KAP scoring was done to compare the two groups. Results: The mean age of the rural and urban residents was 31.48 ± 12.05 and 30.93 ± 11.96 years respectively. Only 40.4 % urban and 25.5 % rural people had correct knowledge about social distancing (p<0.0001). Knowledge regarding quarantine for covid-19 disease prevention was less among the urban residents (64.6%) as compared to rural (70.5%) (p=0.035). More than one-third (37.6%) of the rural resident believed in the myth that alcohol can prevent the covid-19 disease (p=0.003). 68.8 and 70.5 percent rural and urban residents had positive attitude towards the Indian government’ efforts in curbing the disease. Majority of the urban (90%) and rural (87.6%) residents wore mask when they went out. Only one-fourth of the urban (24.7%) and rural (22.9%) had correct practices for the duration of hand washing. Conclusion: The knowledge was more among the urban people, attitude and practices were almost similar among both the rural and urban residents while myths were more observed among the rural residents.
