My DD got it when she was TT... This is how I think she got it.

She was in hospital with a drip for fluids, but was walking around annoying us just fine... So maybe a mild dose?

None of my kids have had the vac I dont think... They are 3 and almost 2... would they have had with the normal ones back then?? Harmony hasn't.

There have been some bad reactions, twisted bowels and the like, with the vac, so I have held that one off till she is likely to get it from somewhere. In my eyes she isn't is much danger of catching it, unless one of the other kids get it, and accidently infect her with fecal matter. But I am extremely careful with anyones contact with her.

I will consider it when she starts playing with other kids, toys etc

But I think your right. Its not very dangerous once they are a little older, so I dont think they vac then. Its a short term temporary vac, I *think*.
