Thanks all, I am not so worked up about it now It seems pretty unlikely that I would get it, since I wasn't directly exposed. First my son would have to get it, and the ped said the first vax is 85% effective. She said my getting the vax could still help stave it off, esp since if he did get it, it wouldn't be for 2 more weeks. I ended up just getting the vax from her--baby got to watch mama getting a shot from the ped!!
