The Health Insurance Portability and Accountability Act of 1996, known as HIPAA is a federal law that required the creation of national standards to protect sensitive patient health information from being disclosed without the patient’s consent or knowledge. Most businesses won’t violate HIPAA by asking you if you’ve been vaccinated. HIPAA does not prohibit any person or business from asking whether an individual has received a particular vaccine.For more information, please visit: Health Insurance Portability and Accountability Act of 1996 (HIPAA) | CDC
