Booster shots

• Adolescents. Because immunity from the pertussis vaccine tends to wane by age 11, doctors recommend a booster shot at that age to protect against whooping cough (pertussis), diphtheria and tetanus.
• Adults. Some varieties of the every-10-year tetanus and diphtheria vaccine also include protection against whooping cough (pertussis). This vaccine will also reduce the risk of your transmitting whooping cough to infants.
• Pregnant women. Health experts now recommend that pregnant women receive the pertussis vaccine between 27 and 36 weeks of gestation. This may also give some protection to the infant during the first few months of life.

Preventive medications

If you've been exposed to someone who has whooping cough, your doctor may recommend antibiotics to protect against infection if you:

• Are a health care provider
• Are pregnant
• Are younger than age 12 months
• Have a health condition that could put you at risk of severe illness or complications, such as a weakened immune system or asthma
• Live with someone who has whooping cough
• Live with someone who is at high risk of developing severe illness or complications from a whooping cough infection
