Vaccination records raising privacy concerns in California

The California Public Department of Health’s digital Immunization Information System holds information of California residents who received a COVID-19 vaccination, raising concerns over health data, The Mercury News reports. Privacy advocates say current regulations do not prevent vaccine data from being leaked or sold into data markets, and raised concerns over weakened confidentiality laws and vaccine verification systems. “We’ve got to take a look at vaccine credentialing systems and make sure that we don’t create something we regret,” said World Privacy Forum Executive Director Pam Dixon.
