Adacel® (Tdap vaccine) is a "booster" product used to prevent diphtheria, tetanus, and pertussis in people 11 to 64 years of age. It works by stimulating the immune system to produce antibodies against these particular viruses. This vaccine is given as a single, one-time injection into the deltoid muscle of the upper arm.
Not everyone should receive this vaccine. Inform your healthcare provider prior to receiving Adacel if you have an immune-suppressing condition such as HIV or AIDS, diabetes, or cancer; have epilepsy or any other nervous system disorder; or have an illness or infection, such as the flu.
