I believe that children had stopped testing around 1972 I heard on the news last night that even those who have had the vaccnine are in jeaopardy because too many years have gone by for them to be effective any longer. I can attest to that concept: although I had a measles vaccincation in elementary school, I contracted them as an adult. Very ill and painful.
BTW, I hope our overseas SOURCE for these additional vaccines doses is reliable.
