Pertussis (Whooping Cough)

Pertussis is a highly contagious bacterial disease that can be spread by coughing. People with pertussis have severe coughing attacks that can last for months. Infants too young for vaccination are at greatest risk for life-threatening cases of pertussis.

Protect Vulnerable Infants from Pertussis: Immunize Mothers with Tdap during Every Pregnancy

Pertussis is a continuing threat to Californians, though the magnitude of the threat can vary by year. Over 9,100 cases of pertussis were reported in California during 2010, the most in more than a half-century. After levels dropped in 2011 and 2012, they doubled in 2013 and continue to rise.

Young Infants at Highest Risk of Severe Pertussis

Infants younger than six months of age are most susceptible to hospitalization or death from pertussis. Infants can be protected by maternal antibodies that are transferred through the placenta. Early evidence suggests that maternal immunization with Tdap during the third trimester of pregnancy can prevent pertussis in young infants.

Optimal Timing of Maternal Tdap Administration

To maximize protection of young infants, the federal Advisory Committee on Immunization Practices (ACIP) recommends that all women should be administered Tdap during every pregnancy, preferably between 27 and 36 weeks' gestation. If Tdap is not administered during pregnancy, it should be given immediately postpartum. This will not provide direct protection to the infant, but may prevent transmission of pertussis from mother to infant.

Other Close Contacts

Everyone who anticipates contact with an infant younger than 12 months of age should receive Tdap.

Where to Get Immunizations

The best place to get immunizations is your doctor's office or clinic as part of personal regular health maintenance. Community clinics offer medical care and immunizations to established patients. Those listed with an asterisk * offer limited immunization services to the public, but encourage establishing care as well.
