Welcome to the State of California 

Pertussis (Whooping Cough) 

Whooping cough (also known as 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. Over 9,000 cases of pertussis were reported in California during 2010, the most in over 60 years, including 10 infant deaths. Consistent with a peak in incidence every 3-5 years, CDPH has declared a whooping cough epidemic in 2014. Pertussis is widespread throughout the U.S. and the rest of the world.

Make sure that you have been vaccinated against whooping cough.  Booster doses are needed throughout life, because protection against whooping cough after vaccination or disease wanes over time.

  • Pregnant Women are recommended to receive Tdap (whooping cough booster) in their third trimester (between 27-36 weeks of pregnancy, at the earliest opportunity during this window). Tdap is recommended during each pregnancy, even when given before pregnancy. The protection that expectant moms receive from Tdap also passes to their baby in the womb. This helps protect babies during the most vulnerable period, until they are old enough to get their first whooping cough vaccination at 6--8 weeks of age
  • Infants can start the childhood whooping cough vaccine series, DTaP (PDF), as early as 6 weeks of age. Even one dose of DTaP may offer some protection against fatal whooping cough disease in infants. Young children need five doses of DTaP by kindergarten (ages 4-6)
  • Students in 7th grade in California need to have met the requirement for a Tdap (PDF) booster - see http://shotsforschool.org.
  • Adults are also recommended to receive a Tdap booster, especially if they are in contact with infants or are health care workers, but most adults have not yet received Tdap.
  • Whooping cough vaccination recommendations of the federal Advisory Committee on Immunization Practice (ACIP) are http://www.cdc.gov/vaccines/hcp/acip-recs/index.html.

How Well-Vaccinated Is Your Child's Child Care Facility/School?

Child care facilities with low vaccination rates are at increased risk for outbreaks of vaccine-preventable diseases. Some children are allowed by California law to skip immunizations if a parent submits a personal beliefs exemption (PBE) or medical exemption (PME) at enrollment. Other children, may be admitted to child care on the 'condition' they complete remaining vaccinations when due. Often there is no follow-up and these children remain under-vaccinated.
