Pertussis (Whooping Cough) - Tdap Vaccine
The Fairfax County Health Department is offering free Tdap vaccine to people aged 19 and older. In particular, parents & caregivers of infants, people who come into contact with pregnant women, and healthcare workers, are encouraged to get vaccinated at one of the Health Department's clinic sites. This program will continue while supplies of free Tdap vaccine provided by the Virginia Department of Health last.

Why Adults Need a Tdap Booster
- The protection against pertussis from childhood vaccination fades over time. As a result, adults can become infected with pertussis and spread the disease. (Most people aged 19 years and older should receive a one-time Tdap booster, available for free at one of the Health Department’s clinic sites.)
- Because infants less than one year of age are too young to be fully immunized, they are at highest risk for pertussis infection and its complications including lung infection, seizures, and even death.
- Vaccination of adults with the Tdap vaccine helps to protect the individual and infants by decreasing the overall transmission of pertussis in the community.
- Up to 83% of infants who become infected with pertussis get it from adults who come into close contact with them, such as an older sibling, parent, grandparent, or caregiver. Vaccinating adults helps to keep infants safe by creating a "cocoon" of protection around them.
Pertussis Facts
- Virginia is facing an increase in pertussis, or whooping cough, which is affecting the most vulnerable individuals in our population: infants.
- In 2010, Virginia had 384 reported cases of pertussis, the highest number in six years.
- From 2010 to 2011, the number of reported cases of pertussis in Fairfax County increased 55%.
What is Pertussis (Whooping Cough)?
- Pertussis is a highly contagious respiratory disease spread from person to person by coughing and sneezing. It is caused by the bacterium Bordetella pertussis.
- Pertussis is called whooping cough because of the whooping sound that is made when gasping for air after a fit of coughing. However, not everyone with pertussis will make this sound, particularly older children and adults who have been vaccinated in the past.
Signs and Symptoms
- Because pertussis in its early stages appears to be nothing more than the common cold, it is often not suspected or diagnosed until the more severe symptoms appear.
-
Early symptoms can last for 1 to 2 weeks and usually include:
- Runny nose
- Low-grade fever (generally minimal throughout the course of the disease)
- Mild, occasional cough
- Apnea — a pause in breathing (in infants)
- After 1-2 weeks, the cough worsens and individuals may experience severe fits of coughing, sometimes severe enough to cause vomiting.
