Maximizing HPV vaccine uptake among those at highest risk for cervical cancer is critical. We explored healthcare provider perspectives on factors influencing HPV vaccination among adolescent girls in a community with high cervical cancer rates. ⋯ Providers noted a number of barriers to HPV vaccination, including some perceived parental misconceptions that could be addressed with education about the need for adolescent vaccines and available free vaccine programs. Because community support appears particularly important to Hispanic parents, the use of promotoras - peer liaisons between health organizations and the community - may increase HPV vaccine uptake in this population.

Randomized Controlled Trial Multicenter Study
Phase 2 assessment of the safety and immunogenicity of two inactivated pandemic monovalent H1N1 vaccines in adults as a component of the U.S. pandemic preparedness plan in 2009.
The influenza A/H1N1 pandemic in 2009 created an urgent need to develop vaccines for mass immunization. To guide decisions regarding the optimal immunization dosage and schedule for adults, we evaluated two monovalent, inactivated, unadjuvanted H1N1 influenza vaccines in independent, but simultaneously conducted, multi-center Phase 2 trials of identical design. ⋯ These trials provided evidence for policymakers that a single 15 μg dose of 2009 A/H1N1 vaccine would likely protect most U.S. adults and suggest a potential benefit of a 30 μg dose for the elderly.

We examined the acceptability of the influenza A (H1N1) and seasonal vaccinations immediately following government manufacture approval to gauge potential product uptake in minority communities. We studied correlates of vaccine acceptance including attitudes, beliefs, perceptions, and influenza immunization experiences, and sought to identify communication approaches to increase influenza vaccine coverage in community settings. ⋯ In this population, positive vaccine attitudes and community perceptions, along with previous flu vaccination, were associated with H1N1 and seasonal influenza vaccine acceptance. Increased immunization coverage in this community may be achieved through physician communication to dispel vaccine conspiracy beliefs and discussion about vaccine protection via social media and in other community venues.

Congenital cytomegalovirus (CMV) infection is associated with significant infant morbidity and mortality. A prophylactic vaccine to prevent congenital CMV infection is expected to be available in the near future, and will likely be targeted to adolescent females. ⋯ Under a wide variety of conditions, universal vaccination of adolescent females to protect their future children against congenital CMV infection was cost effective. However, for this to be preferred over not vaccinating, our results suggest that vaccine efficacy against disease would need to be at least 61%.
