This Bangladeshi infant was being immunized, but “cocooning” would also involve vaccinating the mother and other close family members
An infant has very little immunity to viruses


Cocooning, also known as the Cocoon Strategy,[1] is a vaccination strategy that has been recommended by the Centers for Disease Control and Prevention (CDC) in the United States since 2006. It aims to protect newborn infants from becoming infected with pertussis by administering DTaP (tetanus, diphtheria and acellular pertussis) booster vaccine to mothers, family members and any individuals who would come into regular contact with the newborn infant. By vaccinating these individuals with a pertussis booster a pool of persons is established around the newborn who are themselves protected from getting pertussis and passing it on to the young infant, thereby creating a "cocoon" of protection around the newborn. Young infants have the highest rate of pertussis; in 87-100% of all deaths caused by pertussis, the victim is an infant of less than 6 months of age.[1]

Definition

The concept of “cocooning” is simple. A newborn baby has little if any immunity to influenza for the first 12 months of life. To ensure protection for the baby, immediate household contacts (representing its cocoon) are vaccinated against influenza so they won’t transmit the virus to the baby. The program began in July 2006 with pertussis vaccination and it now includes seasonal influenza vaccinations as well.[2]
