My son recently had a confirmed case of h1n1 - my other two kids have been sick, but not confirmed as such.  I have been told that my son does not need the vaccine at this point.  I am 6 mos pregnant - and was sick in June with something that seemed like h1n1 but was also unconfirmed as such. Since I cared for my son while he had an active case of h1n1, and have not gotten ill, do I need the vaccine? I know that the cdc would say "it wouldnt hurt" - but of course I am not sure if I agree with that.  I would like to know what the incubation period is for this virus, and how that compares with teh time period it takes for the vaccine to take effect.  Thanks!!
