What is a cellular pertussis vaccine?

Whole-cell pertussis vaccines contain the entire inactivated organism while acellular pertussis vaccines contain parts (subunits) including the pertussis toxin alone or with components such as filamentous haemagglutinin, fimbrial antigens and pertactin.

Why was DTP vaccine discontinued?

In the US by the mid-1980s, lawsuits related to vaccine safety led several manufacturers to withdraw their DTP vaccines and paved the way to the US National Childhood Vaccine Injury Act in 1986. This act provides funds to compensate for adverse events following immunization.

How long does whole-cell pertussis vaccine last?

About 7 out of 10 kids are fully protected 5 years after getting their last dose of DTaP and the other 3 out of 10 kids are partially protected – protecting against serious disease. CDC estimates that in the first year after getting vaccinated with Tdap, it protects about 7 out of 10 people who receive it.

Is DTaP a whole-cell vaccine?

This whole-cell DTP vaccine (DTwP) has been replaced with acellular DTP vaccine (DTaP) consisting of individual antigens of B.

Is pertussis a virus?

Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis.

What is the difference between DPT and DTaP?

DTaP produces fewer side effects and is a safer version of an older vaccine called DTP, which is no longer used in the United States. Tdap vaccine is licensed for people 10 years through 64 years of age. Tdap contains a lower concentration of diphtheria and pertussis toxoids than DTaP. Tdap is given at 11-12 years.

Why was Heptavax discontinued?

The most common reason for discontinuation was lost to follow-up (mpHBV SC: 3.2%; Heptavax®-II SC: 2.9%; and mpHBV IM: 7.4%) and withdrawal of consent (mpHBV SC: 1.4%; Heptavax®-II SC: 5.7%; and mpHBV IM: 1.1%).

Is it bad to get Tdap before 10 years?

This is especially true in patients at increased risk of pertussis or its complications; the benefit of a single dose of Tdap at an interval of less than 10 years will likely outweigh the risk of adverse reactions to the vaccine. In addition, an interval as short as two years between Td and Tdap is considered safe.

Does pertussis go away on its own?

Pertussis bacteria die off naturally after three weeks of coughing. If antibiotics are not started within that time, they are no longer recommended. Antibiotics can also be given to close contacts of persons with pertussis to prevent or lessen the symptoms.
