Corona virus, also known as SARS-CoV-2, was found to be the cause of the COVID-19 respiratory pandemic in 2019. In the early months of 2020, the World Health Organization recognized SARS-CoV-2 as a new corona virus in response to an epidemic in China. The first incidence of COVID-19 was identified on December 1, 2019, and the primary issue was a newly discovered corona virus known as SARS-CoV-2. Three to four weeks after the initial dosage, the COVID-19 vaccination against corona virus offers adequate protection. For long-term protection against corona virus, it's vital to acquire all of the required immunization doses. The study comprised 260 COVID19 patients, ranging in age from 20 to 70 years old, who were hospitalized to the Aziz Bhatti Shaheed hospital in Gujrat between Januarys to June 2021. A cross-sectional investigation is carried out using a practical sampling strategy. Clinical records were used to acquire patient information such as illness beginning date, clinical categorization, and personal demographics. The research comprised 260 COVID19 patients who were hospitalized to the hospital and ranged in age from 20 to 70 years old. The study demonstrates that vaccines have a significant impact on human immunity and, as a result, aid in disease prevention. This study demonstrates that immunization can help avoid COVID-19 outbreaks even if it only provides little protection against disease. Getting immunized with COVID-19 seems to be a more reliable and secure strategy to build immunity than contracting the virus directly.
