Abstract

Background. The COVID-19 vaccination campaign began in Italy at the end of December 2020, with the primary aim of immunizing healthcare professionals, using the EMA approved mRNA vaccines (Comirnaty® by Pfizer/BioNTech; mRNA-1273 by Moderna) and recombinant adenoviral vaccine (Vaxzevria® by AstraZeneca). The study aimed at evaluating the prevalence and motivations underlying Vaccine Hesitancy, as well as the incidence and type of adverse events associated with COVID-19 vaccination.

Methods. Cross-sectional study. Data were collected January 1st to 28th 2021 using a purposely created online self-administered questionnaire from a selected cohort of Italian physicians.

Results. Overall, 7,881 questionnaires were analyzed: 6,612 physicians had received one dose, and 1,670 two doses of Comirnaty®; 30 had received one dose of mRNA-1273. Vaccine Hesitancy rate was 3.6%; it correlated with prior SARS-CoV-2 infection, diabetes, Adverse Eventss at previous vaccinations and refusal of 2020 flu vaccine, and was mainly motivated by concerns about vaccine Adverse Events. Typical Adverse Events were pain/itching/paresthesia at the inoculation site, followed by headache, fever, fatigue and myalgia/arthralgia occurring more frequently after the second dose (77.8 vs 66.9%; p<0.001), and in subjects with a prior SARS-CoV-2 infection.

Conclusion. Adherence to COVID-19 vaccination is high among physicians. Adverse Events are typically mild and more frequent in people with a prior SARS-CoV-2 infection.
