Personal information collected during the coronavirus vaccine sign-up process would be protected by health privacy legislation introduced Thursday by Democrats seeking to allay fears of data misuse and encourage vaccinations.

The bicameral Public Health Emergency Privacy Act, first introduced last year, is intended to safeguard people’s privacy and health data by restricting the information the government collects and stores through activities such as contact tracing, virus testing, and patient care. Information collected by the government during the vaccine sign-up process would now also be protected by the legislation.
