Aim: Covid infection after first and second dose of vaccination was assessed in comparison to unvaccinated SARS-CoV-2 infection patients.

Methodology:  Patients were divided into two groups: those who had not got any immunizations and those who had received vaccines that were prescribed. Individuals who have taken second dose of either the mRNA vaccine or the viral vector vaccine and have a positive COVID-19 within 14 days of receiving their second dose are deemed fully immunised.

Results: Among 180 patients, the males were 75% and 25% was females. In our study, 16.7% (30/180) patients still suffered from COVID-19 despite of the fact that they were vaccinated, but the ratio of immune patients was greater i.e. 83.3% (150/180).The severity of the symptoms in vaccinated patients was much lesser and in some cases almost nil. 144/180 (80%) patients did not suffer from any severe symptoms after vaccination. 33/180 (18.3%) patients showed moderate symptoms while 3/180 (1.7%) showed severe symptoms. In the analysis of severity of symptoms of non vaccinated patients, 70% (126/180) showed severe symptoms, 25% (45/180) showed moderate and 5% (9/180) patients showed low symptoms.

Conclusion: People without vaccination have more severe symptoms whereas COVID patients with vaccination had a reduced mortality rate and milder symptoms.
