Evaluation of the effect of vaccination and its consequences in patients with COVID-19 in western Iran

The confirmed cases of the new coronavirus disease (COVID-19) have increased not only in China but also in Iran and around the world. COVID-19 vaccination not only protects the individual but also safeguards those in the community who are unable to be vaccinated. Due to this concern, the present study was conducted to determine the relationship between vaccination and its consequences in patients with COVID-19.

This descriptive study was conducted in Asadabad city, in western Iran. The data for this project were collected from the database and records of patients with COVID-19 in Asadabad Health Department. In fact, the sample size included all patients with a positive PCR diagnosis in the year 2022. Nine hundred fifty-one patients were included in the study. The tool used was a checklist based on patient records. SPSS software was used to analyze the data, and a significance level of less than 0.05 was considered.

The mean age of patients with a positive PCR test was 20.8 ± 42.9 years. Of these, 68.5% were vaccinated, and 31.5% were not vaccinated. Among the 951 patients, 30 patients with a positive PCR died, 19 of whom were not vaccinated. There was a significant relationship between the outcome of the disease (death or discharge) and the number of vaccine doses (p value = 0.001).

Due to the effectiveness of COVID vaccination in reducing hospitalization and mortality, it is recommended to design educational interventions to encourage people to increase vaccination coverage.
