It was Rose Kennedy, mother of President John F. Kennedy and Robert Kennedy, Sr., who kept a card file of all her children's vaccinations--and I'm sure RFKJr.'s mother Ethel did as well. None of those Kennedy kids ever had polio or measles or other deadly diseases. In fact, vaccines ERADICATED polio in the U.S.! Just this week In Texas, one case of measles has been found. Imagine how many others there will be under RFKJr & trump!
