CBS At least 3% of measles cases confirmed so far this year have been in people who received two doses of the measles vaccine, meaning they were fully vaccinated, the Centers for Disease Control and Prevention says.
About three dozen of the nearly 1,200 measles infections in 2025 have been in people with two vaccine doses, the agency said Friday in its weekly update on cases. An additional 2% of cases were in people who received at least one dose of the measles vaccine.
Many of the cases were in Texas, which on Tuesday counted a 21st confirmed measles case in someone with at least two doses of the vaccine.
