Introduction: Acute respiratory infection (ARI) is a severe infection that affects a person's respiratory system and causes breathing problems. Coronaviridae is one of the viral families that cause respiratory infections in birds and mammals. The efficiency of vaccination against COVID-19 infection is undeniable so this study aimed to evaluate the symptoms of SARS-CoV-2 in people who received four doses of the Sinopharm vaccine
Methods: This study evaluated the prevalence and severity of COVID-19 infection in vaccinated people with four doses of sinopharm vaccine. All samples were collected from patients with respiratory symptoms who were referred to Besat hospital, Tehran, Iran
Results: From 290 patients with respiratory symptoms, 109 patients were positive for COVID-19 infection with a history of four doses of Sinopharm vaccine and the most common clinical symptom of infection were cough, runny nose, and fever but the hospitalization rate was very low.
Conclusion: Although vaccination can’t prevent infection with SARS-CoV-2, but against COVID-19 infection seems to be beneficial in reducing symptoms and hospitalization rate, especially if they have received a forth booster dose.
