Health departments in Philadelphia and most other counties in the region plan to schedule flu vaccine clinics in fall 2010. They will be posted on this page. Many physicians offices will also have vaccine. Several retail chains are already offering vaccine or will do so soon.
What it protects against: The 2010-11 seasonal flu vaccine strengthens immunity against the three strains of influenza that experts believe are most likely to circulate this season. They are formally known as A/California/7/2009 (H1N1)-like, the same as what was in the single-strain swine flu vaccine last year; A/Perth/16/2009 (H3N2)-like; and B/Brisbane/60/2008-like.
Who should get it: The U.S. Centers for Disease Control and Prevention this year recommended for the first time that all Americans over 6 months of age be vaccinated either by injection (all are eligible) or FluMist nasal spray (only healthy, nonpregnant people between 2 and 49 years of age).
