How Does It Work?Boostrix contains diphtheria and tetanus toxoids and pertussis antigens. Toxoids are bacterial toxins that have been detoxified. Although the toxoids will not cause the actual disease, they stimulate the immune system to produce antibodies to the toxin.
"Antigen" is the generic term for substances that cause the body to produce an immune response and antibodies. Boostrix contains three different pertussis antigens that have been detoxified.
Basically, the antigens and toxoids in Boostrix "trick" the body into thinking it has been exposed to diphtheria, tetanus, and pertussis. The body produces antibodies that will help fight these diseases if future exposure occurs.
