So I went to Taichung, tried to go to the Center for Disease Control, only to find that it had moved from the present site for two years. Ain't bureaucracy grand?
Still, thanks to joesax for giving me the information.
After the security guard at the site, which was a bank, gave me the correct address, I had to get a taxi all the way to the boonies and they outright refused to give me a rabies vaccination, saying that it wasn't needed even though I explained that I was going to a high-risk area. Again, ain't bureaucracy grand?
