Klein, M.D., Ph.D., FAAP and director of the Vaccine Study Center at KPNC, said of the research: While the pertussis vaccines don’t last as long as we would like, they do work and they are effective. The study found that for unvaccinated children, the risk of contracting the illness was 13 times higher than the vaccinated population.Īs study co-author Nicola P. The important thing to note though is that the vaccine does work, as CNN reported.

The new study, published on Monday, is the work of researchers from Kaiser Permanente Northern California (KPNC).
And this new study shows, as CNN reported, that missing just one dose can result in an up to five times increase in the susceptibility of getting whooping cough. According to the HSS, the vaccinations are supposed to be given at two, four, and six months of age, then 15-18 months and finally at 4 to 6 years old. Department of Health and Human Services (HSS) call for five doses of the DTaP vaccine, which inoculates a child against diphtheria, tetanus and pertussis, the name for whooping cough.
