From the shameless self-promotion board:

The Houston Public Library and the CHRISTUS Nursing Association have partnered to make flu shots available to those Houstonians who have not been vaccinated against the flu virus. The shots will be offered at two neighborhood libraries on three Saturdays during the month of January, from 11 a.m. until 2 p.m. There will be a $30 fee per shot; shots will be free for seniors on traditional Medicare.
