My son had rotovirus four times (this was before the vaccine was available)...there are I believe around ten different strains. My husband and I did not catch it from him. I guess we already had it as kids, or we used good hygiene.
It was horrible...seven to ten days of first vomiting, first few days then the diarrhea from hell...it literally smelled like a rotting corpse. I always knew it was rotovirus by the smell and color of the diarrhea.
When they told me they had a vaccine for it and did I want my daughter to get it...I was very excited not to have to go through those horrible stomach bug days again.
Is it a live virus vaccine? Or is the virus dead? In the vaccine...if it is a live weakened virus then I guess you could catch it...but it is spread through poop.
I don't know that I have ever heard of someone being contagious from getting a vaccine...ummm, gotta go look that one up...
