Résumé
Though vaccines have been in use for over seventy years, we have been unable to eradicate or control pertussis. This disease is a worldwide problem, and recently has been occurring in outbreaks even in places with good immunization coverage. The debate about the use of acellular or whole cell vaccine has taken attention away from the other significant issues. The high rate of serious disease and death in young infants, and the repeated outbreaks of pertussis even in highly-vaccinated populations is a matter for grave concern. Finding strategies to protect the most vulnerable is a priority. Newer vaccines are under development, and will be welcome, but may be too expensive for mass use in resource-poor nations. It is important to adopt cost-effective strategies to deal with this disease.
