Then a few paragraphs below I found the following:
In other words HIPPA Rules do include disclosure of immunization records to schools. You appear to be correct - every school in the country has broken the law. I am somewhat surprised that no one has figured this out yet. Note that businesses cannot access personal records for employment and I think the airlines have a problem as well. HIPPA was initially passed to protect those that had the AID virus - which BTW was at the time listed as a pandemic. It looks like when the law was made that there was not a lot of foresight.
No they do not apply to schools. Schools have not been breaking any laws regarding requiring proof of vaccinations. According to the Hipaa laws:
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.
Hipaa only applies to healthcare facilities not being allowed to release information. However businesses and schools can require proof of vaccines. As well as traveling to specific countries, military service, requiring tetanus shots for some professions and of course our missionaries are required to have certain immunizations and must provide proof.
I worked for a health insurance company for 10 years. Knowledge of Hipaa laws was something we had to pass tests on as part of our employment to ensure we weren't breaking any laws.
