Pennsylvania school districts linked parents to anti-vaccine sites as immunization gaps widened
A Pittsburgh Post-Gazette investigation found that at least 20 Pennsylvania school districts linked parents to Vaclib.org, an anti-vaccine site, via exemption forms as vaccination rates fell and herd immunity weakened in dozens of elementary schools. While a state ad campaign aimed to boost immunizations, districts broadly shared the misinformation—some without realizing it—that then was removed after media inquiries. The findings highlight a lack of centralized oversight and enforcement of vaccine laws in Pennsylvania, and raise concerns about contributing to measles risk as districts face divergent messaging about vaccines.
