EVALUATION OF THE EFFECTIVENESS OF TDAP VACCINATION STRATEGIES AT PREVENTING INFANT PERTUSSIS
The Pertussis Vaccination Evaluation is a national case-control study and a collaboration of the California Emerging Infections Program (CEIP) Network and the Centers for Disease Control and Prevention. The study’s main aim is to compare the effectiveness of two different vaccination strategies at preventing pertussis infection in infants less than 12 months of age. Data collection includes telephone interviews with the parent or guardian of infants and adults in regular contact with the infant, as well as collecting vaccination information from medical providers. SRG pilot-tested and subsequently administered the telephone survey for the control participants in California.
