Funny you should ask this question. I've been debating this vaccination for years. Amanda has been bitten/attacked by monkeys twice (yes twice, once in Kenya and once in Thailand) since we've been on the road.

Now we are in Bangkok where we can get the vaccination from the Thai Travel Clinic (part of the Hospital for Tropical Diseases in Bangkok) at a fraction of the U.S. cost (rabies costs $9), yet Amanda is hesitant to get it (imagine that!)... and so am I, to some extent.
