Sure. Let’s get it straight from HIPAA itself. Here’s the HIPAA LInk https://www.hipaajournal.com/is-it-a-hipaa-violation-to-ask-for-proof-of-vaccine-status/amp/ Here’s a quote from HIPAA: “HIPAA and Proof of Vaccine Status” 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. It would not be a HIPAA violation for an employer to ask an employee’s healthcare provider for proof of vaccination. It would however be a HIPAA violation for the employee’s healthcare provider to disclose that information to the employer unless the individual had provided authorization to do so. If an employer is running their own vaccination program and an employee chooses to have their vaccine privately, that individual may have to authorize their healthcare provider to disclose certain information about their vaccine to their employer as proof that they have been vaccinated. Asking about vaccine status would not violate HIPAA but it is possible that other laws could be violated. For instance, requiring employees to disclose additional health information such as the reason why they are not vaccinated could potentially violate federal laws. Furthermore, several states have passed laws – or are considering laws – that prohibit employers in the public sector from asking employees about their vaccine status.
