1 Because of the rise in US pertussis cases, some people should not wait 10 years to get their Tdap booster. 2  Pregnant women especially need Tdap vaccine because of the protection it provides against whooping cough. 3  They should get it late in the second trimester or in the third trimester.
It is not known how long the Tdap vaccine will provide protection against pertussis. A booster dose (of Td only) is recommended for adults every 10 years. The booster dose may be needed sooner if an adult gets a dirty wound or cut.
