Abstract

Background: Pertussis, or Whooping cough, is a highly contagious respiratory infection that can cause severe complications in infants and young children. Over half of infected infants under 1 year of age require hospitalization and many will develop apnea or pneumonia[superscript 7]. Vaccination is the most effective method to protect children and infants from pertussis. The Advisory Committee on Immunization Practices (ACIP) recommends four doses of pertussis-containing vaccines given at 2, 4, 6, and between 15 and 18 months of age[superscript 7]. The national Healthy People 2010 goals aimed for 90% coverage of two year olds up-to-date with recommended childhood vaccines, including pertussis-containing vaccines[superscript 24,29]. Unfortunately, Oregon did not meet this goal. Methods: Cross-sectional data from the 2007 to 2009 National Immunization Survey (NIS) was used to examine the relationship between sociodemographic factors and up-to-date pertussis immunization in 19-35 month old children in Oregon to identify factors that prevented coverage rates from meeting national goals. Results: Children who were up-to-date with pertussis immunizations were older, had fewer gaps in insurance coverage, had fewer siblings younger than 18 years old, were more likely to have their interview conducted in Spanish, and had more educated mothers. Conclusions: These results will help inform the development of targeted public health interventions to expand immunization coverage to meet national goals and protect infants and children from a potentially serious and deadly disease.
