The current pertussis outbreak occurring in California clearly demonstrates that we need to make a greater effort to vaccinate adults in order to protect infants too young to be completely vaccinated. To quote the 2010 editorial by Dr. Alfred DeMaria Jr. and Dr. Susan Lett, “If it does takes a village to raise a child, then that village should be fully immunized against pertussis” (Clin. Infect. Dis. 2010;50:1346-8).
