The CDC has declined to include two child deaths from measles reported by Pennsylvania's health department in its official outbreak tally, departing from its usual practice of accepting state-reported data.

Kennedy Jr. and Pennsylvania Governor Josh Shapiro, after Shapiro blamed vaccine misinformation for the deaths and Kennedy accused him of fabricating the incident.
