I wanted to add that we fully intended to get DS vaccinated as soon as possible. The problem was with the distribution in our area -- clinics had it and weren't distributing it. Referrred everyone to the flu shot blitzes. We fought long and hard to get DS vaccinated.
Normally healthy people in our area were getting very sick, people ending up on vents... So we spent a few months fearful that DS might get H1N1 before we could get him vaccinated.
