> MMR vaccinated in 1985. Within two weeks was deaf on my left side from encephalitis.
Encephalopathy has been reported after MMR vaccination at a rate of less than 1 per 1 000 000 doses administered. Epidemiologic reviews conclude that the observed rate is no higher than background rates of encephalitis in unvaccinated populations, making a causal link uncertain.
Measles infection itself carries a risk of encephalitis in about 1 in 1 000 cases—roughly 1 000 times higher than the vaccine-associated rate. Beyond acute encephalitis, measles can also lead to late‐onset “subacute sclerosing panencephalitis” (SSPE), a fatal degenerative brain disease years after infection.
