I believe it's measles that is nearly fatal in the unborn and infants, causing organ damage and blindness. There's a story of a US Marine escaping from measles quarantine in the US to visit Gene Tierney, a Hollywood starlet, in town who was pregnant, and the infant being born with severe life-long complications. That is the argument for people to get vaccinated - to protect via herd-immunity those that cannot get vaccinated. https://dev.vijeejournalist.com/2015/07/agatha-christie-mmr/ https://dev.vijeejournalist.com/2015/07/agatha-christie-mmr/
