A school-age child in Los Angeles County who had measles as an infant has died of a rare complication, the county health department said Thursday. The child was infected before they were eligible to receive the measles vaccine, the agency says; the first vaccination is recommended between 12 months and 15 months of age, followed by a second dose between ages 4 and 6. They recovered from that infection but developed a condition called subacute sclerosing panenecephalitis, which affects about 1 in 10,000 unvaccinated people who get measles overall but up to 1 in 600 of those who catch the virus in infancy.
