How can we protect children over 7 years of age from pertussis if they had not received a full series?
You cannot vaccinate these kids unless it is part of a controlled study under a protocol. If a child has only had one or two doses of DTaP and is in an environment, like school, where there is an outbreak, they are not protected. The best advice is to remove them from the situation until the outbreak settles down. They should be watched closely for any signs and symptoms of cough illness.
