BACKGROUND We conducted a 5-year follow-up study on the persistence of pertussis-specific antibody and cell-mediated immunity after booster immunization of adolescents aged 11-13 years with a tricomponent acellular pertussis vaccine (Boostrix; trials diphtheria-tetanus-acellular pertussis [Tdap]-004/030). METHODS Cellular and humoral immunity to pertussis toxin (PT), filamentous hemagglutinin...
BACKGROUND A significant waning of enterovirus 71 (EV71) antibody titer after priming immunization with an inactivated EV71 vaccine implied the potential need for a booster dose. METHODS In this randomized, double-blind, placebo-controlled clinical trial, we recruited participants who had received at least 1 dose of priming EV71 vaccine in an early phase 2 clinical trial that was conducted in...
A flight test article, called a glove, is required for a Mach-8 boundary-layer experiment to be conducted on a flight mission of the air-launched Pegasus® space booster. The glove is required to provide a smooth, threedimensional, structurally stable, aerodynamic surface and includes instrumentation to determine when and where boundary-layer transition occurs during the hypersonic flight trajec...
OBJECTIVES This article presents the response of a child-size postmortem human subject using a booster seat in a series of three frontal impact sled tests. METHODS A 54-year-old female cadaver was seated in a booster seat in the rear seat of a buck representing a mid-sized American sedan. Two different restraint systems (conventional belt and pretensioning, force-limiting belt) were used to r...
Pertussis is the only vaccine-preventable disease on the rise in the United States, with increasing incidence in adolescents and adults related to waning immunity. Although often considered a relatively mild infection in these populations, pertussis can be a serious, potentially deadly illness, particularly in children <12 months old. Infected adolescents and adults serve as a reservoir for dis...
BACKGROUND Whether hepatitis B (HB) vaccine-conferred immunity persists into adulthood is unknown. We aimed to investigate long-term HB immunity in adolescents. METHODS In 2004-2005, 6156 high school students (15-21 years old) who had been vaccinated with plasma-derived HB vaccine as infants were recruited for HB seromarker screening. The immune response to an HB vaccine booster was evaluated...
This manuscript reports the results of an evaluation of two community-based booster seat promotion programs in Michigan; one program focused on a low-income community, while the other focused on a Hispanic community. Each community received funding to develop and implement a booster seat intervention program specific to their community. To determine the effectiveness of each program, direct obs...
BACKGROUND AND AIMS The duration of the protection of hepatitis B vaccination for infants and the necessity of a booster dose administration is unknown. The aim of the present study was to evaluate the persistence of seroprotection after hepatitis B virus (HBV) vaccination in order to determine the necessity of a single booster dose in 5- to 7-year-old children. METHODS This clinical trial st...
Background: Patients with rheumatologic immune-mediated diseases (R-IMID) Latent tuberculosis infection (LTBI) requiring biologic therapy (BT) are at an increased risk of active (TB). Screening LTBI tuberculin skin test (TST) and/or Interferon (IFN)-γ release assays (IGRA) is recommended before starting BT. Objectives: In patients R-IMID previously to BT our aim was assess a ) prevalence LTBI, ...
