Vaccination information is classed as PHI and is covered by the HIPAA Rules. However, HIPAA only applies to HIPAA-covered entities – healthcare providers, health plans, and healthcare clearinghouses – and their business associates. If an employer asks an employee to provide proof that they have been vaccinated in order to allow that individual to work without wearing a facemask, that is not a HIPAA violation as HIPAA does not apply to most employers.
