Quinn plans to get his flu shot Tuesday in Chicago from the state's
official top doctor, Illinois public health director Damon Arnold.
Health officials say vaccination is the single best way to protect
against catching the virus that causes regular winter influenza.
Preventing swine flu will require a separate vaccine, expected to
be available in October. That vaccine may require two shots, spaced
about three weeks apart.
The federal government has begun studies to test the swine flu
shot's effectiveness and figure out the best dose. Vaccine makers
are doing their own tests as well.
