Any place in the US that requires appointments has never been reliable for me. If I went that route I would have to wait weeks to months to get a vaccine or PCR test. Instead, poorer neighborhoods usually have hospitals or health centers that offer walk-up or drive-through services for vaccinations and tests. Sadly, most of the people in those neighborhoods don't use the services, so if you go right when they open you can get vaccinated or a PCR test with barely any wait. I waited 5 minutes to get my vaccine in Miami, and I waited about 15 minutes in a drive-through in Boston to get a PCR test with results the next day.
