Kinrix is a combination vaccine used for preventing polio, diphtheria, tetanus, and pertussis. It works by "tricking" the body into thinking it has been exposed to these different infections. The vaccine is typically given as a single booster dose for children four to six years old. Potential side effects include drowsiness, fever, and reactions at the injection site.

Thimerosal Content and Other Concerns
Kinrix does not contain thimerosal (a mercury-containing preservative). Parents who are concerned about exposing their children to thimerosal can be confident that this vaccine has no thimerosal -- not even trace amounts. Some parents also are concerned about the aluminum content of vaccines; Kinrix does contain aluminum (0.6 mg per dose).
Unlike some vaccines, Kinrix is not made from human fetal components. While it is made using bovine (cow) materials, the bovine materials come from countries that do not have (or are not at high risk for) bovine spongiform encephalopathy (mad cow disease). In addition, part of this vaccine is grown in a line of monkey kidney cells.
