Cytomegalovirus (CMV) is a leading cause of congenital infection and an important target for vaccine development.CMV seronegative girls between 12 and 17 years of age received CMV glycoprotein B (gB) vaccine with MF59 or saline placebo at 0, 1 and 6 months. Blood and urine were collected throughout the study for evidence of CMV infection based on PCR and/or seroconversion to non-vaccine CMV antigens...
The United States experienced a substantial increase in reported pertussis cases over the last decade. Since 2005, persons 11 years and older have been routinely recommended to receive a single dose of tetanus toxoid, reduced diphtheria toxoid and acellular pertussis (Tdap) vaccine. The objective of this analysis was to evaluate the potential impact and cost-effectiveness of recommending a second...
Many youth with special health care needs (YSHCN) have not received recommended adolescent vaccines, yet data are lacking on correlates of vaccination among this population. Such information can identify subgroups of YSHCN that may be at risk for under-immunization and strategies for increasing vaccination.We analyzed weighted data from a population-based sample of parents with an 11- to 17-year-old...
To examine the association between risk perceptions after human papillomavirus (HPV) vaccination and sexual behaviors and sexually transmitted infection (STI) diagnosis over 30months following vaccination.Participants included 112 sexually experienced girls aged 13–21years who were enrolled at the time of first HPV vaccination and completed ⩾2 of 4 follow-up visits at 2, 6, 18, 30months and including...
Quadrivalent meningococcal conjugate vaccines (MenACWY) were developed to offer long-term protection against invasive disease caused by serogroups A, C, W, and Y. Reduced MenACWY effectiveness within 5 years after primary vaccination (likely due to declining bactericidal antibody titers) has been described, particularly with respect to C and Y disease in the United States. We evaluated the safety...
Due to waning immunity, infant vaccination with meningococcal serogroup C conjugated (MenCC) vaccines is insufficient to maintain long-term individual protection. Adolescent booster vaccination is thought to offer direct protection against invasive meningococcal disease (IMD) but also to reduce meningococcal carriage and transmission and in this way establish herd protection in the population. Previously,...
One of the strategic objectives of the 2011–2020 Global Vaccine Action Plan is for the benefits of immunisation to be equitably extended to all people. This approach encompasses special groups at increased risk of vaccine-preventable diseases, such as preterm infants and pregnant women, as well as those with chronic and immune-compromising medical conditions or at increased risk of disease due to...
