What is Pertussis?

Pertussis is also known as whooping cough. It is a contagious respiratory infection. Older children and adults may have symptoms similar to a common viral chest cold. Infants are more likely to have serious complications that may lead to hospitalization and death. Pertussis is a vaccine preventable disease.

  

What is Cocooning?

Cocooning” is defined as the immunization of family members and close contacts of a newborn. (Global Pertussis Initiative 2011) Cocooning surrounds and protects infants from disease until they have built up immunity through their own immunizations. All people who come into contact with infants should be part of the cocooning for those children.

Tdap Cocooning” means immunizing everyone a newborn (up to 12 months old) comes in contact with, so none of them transmit pertussis (Whooping Cough) to the vulnerable infant. The infant should also be receiving a DTaP vaccination as part of their immunization schedule, starting at two months, to build immunity over time.

Some hospitals provide Tdap vaccine for only the mother of newborns. This is partial “cocooning.” The newborn is much better protected if both parents are vaccinated prior to leaving the hospital, and all other family members are encouraged to be vaccinated as soon as possible to protect the infant.

It takes 10-14 days for the immune system to build antibodies. Parents and family members are NOT protected from pertussis immediately upon receiving the vaccine and should consider getting a Tdap several weeks or months before the newborn arrives.
