Ugh, that immunoglobulin SUCKS, especially when you get bitten on the finger and they try to inject a vial of it all over your hand. (This happened to me about a year ago). When I was at the emergency room for the same thing, they kept asking me if I "still had the bat" and I was all "... um... no. Did not occur to me to put a live bat in my purse before leaving for the emergency room."
