Eighty House Republicans voted with Democrats on Tuesday to pass the Immunization Infrastructure Modernization Act, which if passed by the Senate and signed into law would fund a federal vaccination database. According to the bill, also called H. R. 550, the government would provide $400 million in taxpayer dollars to fund “immunization system data modernization and expansion,” a system otherwise defined as “a confidential, population-based, computerized database that records immunization doses administered by any health care provider to persons within the geographic area covered by that database.”
