Abstract

Vaccination against SARS-CoV-2 is the most important weapon in the arsenal in the battle against COVID-19. There is concern about an increased risk of adverse effects in patients with transfusion-dependent thalassemia (TDT), which affects vaccine acceptance. A predesigned questionnaire was used to evaluate adverse effects (local/systemic within 90 days after vaccination) in participants >18 years of age with TDT. A total of 100 patients received 129 vaccine doses. The mean age of the patients was 24.3 ± 5.7 years, and M:F ratio of 1.6:1. Covishield (Serum Institute of India) was administered to 89% of the participants, and Covaxin (Bharat Biotech Limited) to 11% of the participants. Adverse effects were documented in 62% of the respondents and were more pronounced after the first dose (52%) compared to the second dose (9%). The most frequent adverse effects were pain at the injection site (43%) and fever (37%). All adverse effects were mild and none of the participants required hospitalization. There were no differences in adverse effects among different vaccines, in the presence or absence of comorbidities, blood groups, or ferritin levels. The SARS-CoV-2 vaccine appears to be safe for patients with TDT.
