Generally, employee vaccination information is treated as confidential, but can be shared in certain instances. For example, an employer may be asked to demonstrate compliance with the requirement related to employee vaccination status if the County receives information suggesting that the employer has not complied. The State Occupational Safety and Health Administration (Cal/OSHA) may also request documentation from an employer demonstrating that they have complied with all of the requirements specific to employees who are vaccinated versus unvaccinated, and knowing which employees are vaccinated will allow employers to comply with those requirements.
