COVID-19 Vaccine and Fitness to Fly

INTRODUCTION: On December 2020 the U.S. Food and Drug Administration (FDA) authorized the emergency use of Pfizer-BioNTech COVID-19 vaccine. This new vaccine has several side effects that can potentially impair function, which warrants special attention regarding aircrews' fitness to fly following vaccination. METHODS: A survey was conducted in the Israeli Air Force (IAF) Aeromedical Center in order to characterize the side effects and their duration following Pfizer-BioNTech COVID-19 vaccine administration to aviators. RESULTS: The most common side effect was injection site pain. Headache, chills, myalgia, fatigue, and weakness were more common following the second dose administration. The difference is statistically significant. Following the second vaccine, duration of side effects was longer compared to the first vaccine (P-value = 0.002). CONCLUSION: The IAF Aeromedical center policy for Pfizer-BioNTech COVID-19 vaccine recipients among aircrew members, based on side effects duration and severity, is to temporarily ground from flight duties for 24 and 48 h following the first and the second dose, respectively.
