There is another recent thread on this topic. My suggestion is to go to your PCP and ask for it. If you have insurance, it will just cost your copay. Otherwise, look up health clinics in the yellow pages. Find any clinic. My guess is that the cost is about 50 bucks. And it's not just one shot, it is a series of three boosters taken over a 6 month time period. So if you are going to UHS, start it soon!
