Short-time Safety of the Sinopharm COVID-19 Vaccine in Patients with Hemophilia

Abstract

Background: The COVID-19 pandemic, caused by SARS-Cov-2, has affected the care of patients with hemophilia, indicating the necessity of their vaccination. Nevertheless, there are concerns about using anti-SARS-Cov-2 virus vaccines for hemophilic patients, particularly concerning bleeding adverse events. Methods: Following a cross-sectional design, all adult hemophilic patients who received two doses of Sinopharm anti-SARS-Cov-2 virus vaccine in Afzalipour Hospital, Kerman, Iran, during May and June 2021 were recruited. The participants were followed for two weeks after receiving each dose of vaccine. Results: Fifty-one patients with a mean age of 37.07 ± 11.45 years were included, of whom 27 (61.4 %) patients experienced at least one adverse reaction. Pain was the most frequent local adverse event (occurred in 20 (39.2%) and 15 (29.4%) cases after 1st and 2nd doses, respectively). Menometrorrhagia and epistaxis were reported by two and one patients, respectively. Conclusions: Overall Sinopharm anti-SARS-Cov-2 virus vaccine seems to be safe for patients with hemophilia in the short term.
