Roald Dahl/Patricia Neal had a daughter that died from measles encephalitis. Rare then, but even rarer now with measles vaccinations.
(Just happened to look up Dahl the other day...)
And children die of complications of the common cold
Don’t even go there. I read Dahl in his own words talk about how he gave all kinds of drugs to his other daughter. So perhaps he did the same to the one who had measles too, weird family.
