Though the 2011 flu season is still three months away, flu vaccines are already on the way.
Looking to avoid a potentially crippling shortage of vaccines, some drug manufacturers are disbursing shipments early.
This year’s formulation is similar to last year’s, offering protection against a range of type A and B strains. This includes the H1N1 virus, otherwise known as swine flu.
Even if you had a flu shot last year, you’ll need it again this time around. The immunity offered only lasts for a short period.
The CDC recommends influenza vaccination for anyone six months and older.
