Generic Name: Pertussis Vaccine – Acellular Combined with Diphtheria and Tetanus Toxoids (Adsorbed)
Product Name: Adacel
Indication: What Adacel is used for
This vaccine is for use as a booster in persons from the age of 10 years who have previously received childhood immunisation.
Adacel is not intended for childhood immunisation.
The use of Adacel should be determined on the basis of official recommendations and by your doctor.
Whooping cough, tetanus and diphtheria cause significant sickness and sometimes death in unvaccinated infants, children, and adults.
Action: How Adacel works
Adacel works by causing the body to produce its own protection against whooping cough, tetanus, and diphtheria. It does this by making substances called antibodies in the blood, which fight the bacteria and toxins that cause these diseases. If a vaccinated person comes into contact with these bacteria and toxins, the body is usually ready to destroy them.
It usually takes several weeks after vaccination to develop protection against these diseases.
A course of whooping cough, tetanus and diphtheria vaccine is usually given during early childhood at 2, 4 and 6 months of age, followed by a booster at 4 years of age. In case of whooping cough, tetanus and diphtheria, a second booster is required at the age of 15-17 years.
Most people will produce enough antibodies against these diseases. However, as with all vaccines, 100% protection cannot be guaranteed.
The vaccine will not give you any of these diseases.
The chance of a severe reaction from Adacel is very small, but the risks of not being vaccinated against these diseases may be very serious.
Adacel contains the active ingredients 2.5 mcg pertussis toxoid, 5 mcg pertussis filamentous haemagglutinin, 5 mcg pertussis fimbriae types 2 and 3, 3 mcg pertussis pertactin, 2 or more IU diphtheria toxoid, and 20 or more IU tetanus toxoid. It also contains other ingredients aluminium phosphate, Phenoxyethanol, formaldehyde, glutaraldehyde, and water for injections.
The manufacture of this product includes exposure to bovine materials. No evidence exists that any case of vCJD (considered to be the human form of bovine spongiform encephalopathy) has resulted from the administration of any vaccine product.
