Effectiveness of Prenatal Tetanus, Diphtheria, and Acellular Pertussis Vaccination on Pertussis Severity in Infants

Background. All US women are recommended to receive a tetanus, diphtheria, and acellular pertussis (Tdap) vaccine at 27–36 weeks gestation during each pregnancy to reduce the risk of pertussis to their infants. The impact of this strategy on severity of disease among infected infants has not been evaluated. Methods. We use a retrospective cohort study design evaluating whether ...

Effectiveness of Prenatal Versus Postpartum Tetanus, Diphtheria, and Acellular Pertussis Vaccination in Preventing Infant Pertussis

Background. Most severe and fatal cases of pertussis occur in infants <8 weeks of age, before initiation of the primary pertussis vaccine series. Women are recommended to receive tetanus, diphtheria, and acellular pertussis (Tdap) vaccine at the start of the third trimester of each pregnancy to optimize transplacental transfer of antibodies to the fetus. This recommendation was ...

Validating the Use of Google Trends to Enhance Pertussis Surveillance in California

Introduction and Methods: Pertussis has recently re-emerged in the United States. Timely surveillance is vital to estimate the burden of this disease accurately and to guide public health response. However, the surveillance of pertussis is limited by delays in reporting, consolidation and dissemination of data to relevant stakeholders. We fit and assessed a real-time predictive ...

A Population-Based Study of Neurologic Manifestations of Severe Influenza A(H1N1)pdm09 in California

Background. Reported influenza-associated neurologic complications are generally limited to case series or case reports. We conducted a population-based study of neurologic manifestations associated with severe and fatal influenza A(H1N1)pdm09 (2009 H1N1) cases. Methods. Medical records of patients with fatal or severe (hospitalized in intensive care unit) laboratory-confirmed 2009 ...

Hepatitis A among International Adoptees and Their Contacts

We identified 27 cases of hepatitis A among international adoptees (5 persons), their direct or indirect contacts (20 persons), and unvaccinated travelers to the adoptees' countries (2 persons). Most cases occurred among nontraveling contacts of adoptees, suggesting the need to extend prevention guidelines to include hepatitis A vaccination for at-risk nontravelers.
