We had a playdate and my friend's 2 year old just had his 18 month shots today. He and my 3 year old were drinking out of the same straw. I've really never been concerned about shedding, but I'm curious if there's a risk.
unlikely, but yes there is a risk specifically with the rubella portion of the mmr which is excreted in the nose and throat for up to 28 days.
Well, Rubella would be just fine with me :)
