Hi, I just spoke with a friend who's 4 year old just got some vax, mmr and polio and another one. I told her her son is contagious and my son and pregnant women should not be around him. She checked with her doctor and confirmed what I said, and she's not going to the group activity with me and some others that she planned to.
If it is a friend I'll know about the vaxing, but I can't always know what kids have been recently vaxed.
How do you protect your unvaxed child from contagious recently vaxed children? Especially polio.
