That Would Be Telling@CoQ_10 @BowsacNoodle @Shadowman311 In my reading just now in Wikipedia (I know, I know) a problem with maternal antibodies to RSV was mentioned for infants.
Sounds like the dengue vaccine problem which is an archetypal example of ADE, although they only should be given to someone who's already had it. Which sounds like it was a Phase IV post-marketing discovered problem, vs. the Phase I for RSV which was also much more severe.
