Three COVID-19 vaccines are currently being distributed and administered under federal Food & Drug Administration (FDA) emergency use authorizations. As an employer, you may be considering whether you should require your employees to be vaccinated before they return to the workplace. You may also be concerned about your potential liability if an employee has a severe reaction to the vaccine, or if your unvaccinated employee infects others. You are right to be cautious about these risks and to ask questions about implementing a vaccination policy.
