Abstract
Influenza is a major cause of morbidity and mortality among older adults in the United States, who may also have chronic medical conditions that place them at high risk for complications from influenza. The U.S. Public Health Service recommended influenza vaccination of adults ≥65 y and chronically ill persons since 1961 and beginning with the 2010–11 influenza season, the Advisory Committee on Immunization Practices (ACIP) has expanded its recommendation to vaccinate all persons 6 months of age and older. Medicare coverage for influenza vaccination began in 1993. However, despite the presence of a safe and effective vaccine, long-standing recommendations on vaccination, and federal financial support for vaccination, vaccination levels among adults ≥65 y are not optimal. Studies have shown that influenza vaccination coverage among U.S. adults ≥ 65 y steadily increased from 30.1% in 1989 to 64.2% in 1997, but plateaued near 65% from 1998 to 2013. Increasing influenza vaccination coverage among older adults in the United States will require more cooperation among health-care providers, professional organizations, vaccine manufacturers, and public health departments to raise public awareness about the benefits of influenza vaccination and to ensure continued administration of vaccinations throughout the influenza season.

The Centers for Disease Control and Prevention’s public health response to monitoring Tdap safety in pregnant women in the United States
pages 2872-2879

Abstract
In 2010, in response to a widespread pertussis outbreak and neonatal deaths, California became the first state to recommend routine administration of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine during pregnancy. In 2011, the Advisory Committee on Immunization Practices (ACIP) followed with a similar recommendation for Tdap vaccination during pregnancy for previously unvaccinated women. In 2012, this recommendation was expanded to include Tdap vaccination of every pregnant woman during each pregnancy. These recommendations were based on urgent public health needs and available evidence on the safety of other inactivated vaccines during pregnancy. However, there were limited data on the safety of Tdap during pregnancy. In response to the new ACIP recommendations, the Centers for Disease Control and Prevention (CDC) implemented ongoing collaborative studies to evaluate whether vaccination with Tdap during pregnancy adversely affects the health of mothers and their offspring and provide the committee with regular updates. The current commentary describes the public health actions taken by CDC to respond to the ACIP recommendation to study and monitor the safety of Tdap vaccines in pregnant women and describes the current state of knowledge on the safety of Tdap vaccines in pregnant women. Data from the various monitoring activities support the safety of Tdap use during pregnancy.

Overcoming barriers to HPV vaccination: A randomized clinical trial of a culturally-tailored, media intervention among African American girls
pages 2883-2894

Abstract
Although genital HPV is the most prevalent STI in the US, rates of vaccination uptake among high-risk subgroups remain low. Investigations of vaccine compliance have mainly targeted mother-daughter dyads, which in some settings may prove difficult. This study examines an innovative culturally tailored, computer-delivered media-based strategy to promote HPV vaccine uptake. Data, inclusive of sociodemographics, sexual behaviors, knowledge, attitudes, and beliefs about HPV and vaccination were collected via ACASI from 216 African American adolescent females (ages 14–18 years) seeking services in family planning and STI public health clinics in metropolitan Atlanta. Data were obtained prior to randomization and participation in an interactive media-based intervention designed to increase HPV vaccination uptake. Medical record abstraction was conducted 7 month post-randomization to assess initial vaccine uptake and compliance. Participants in the intervention were more compliant to vaccination relative to a placebo comparison condition (26 doses vs. Seventeen doses; p=0.12). However, vaccination series initiation and completion were lower than the national average. Thorough evaluation is needed to better understand factors facilitating HPV vaccine uptake and compliance, particularly perceived susceptibility and the influence of the patient-provider encounter in a clinical setting.

Vaccination uptake by vaccine-hesitant parents attending a specialist immunization clinic in Australia
pages 2895-2903

Abstract
Vaccine hesitancy (VH) is an issue of global concern. The quality of communication between healthcare providers and parents can influence parental immunization acceptance. We aimed to describe immunization uptake following specialist immunization clinic (SIC) consultation for Australian children of VH parents as a cohort, and according to pre-clinic parental position on immunization. At a single tertiary pediatric SIC (RCH, Melbourne) a retrospective descriptive study classified VH families according to 3 proposed parental positions on immunization at initial clinic attendance. Immunization status at follow up was ascertained via the Australian Children’s Immunization Register and National HPV Program Register and compared between groups. Of the VH cohort, 13/38 (34%) families were classified as hesitant, 21 (55%) as late/selective vaccinators and 4 (11%) as vaccine refusers. Mean follow up post-SIC attendance was 14.5 months. For the overall VH cohort, the majority chose selective immunization (42%) following SIC consultation. When analyzed by pre-clinic parental position on immunization, there was a trend for hesitant families to proceed with full immunization, selective families to continue selective immunization and refusing families to remain unimmunised (p < 0.0001). The most commonly omitted vaccines were hepatitis B (66%) and Haemophilus influenzae type B (55%), followed by the meningococcal C conjugate vaccine (53%) and measles, mumps and rubella vaccine (53%). Immunization outcome appears to correlate with pre-clinic parental position on immunization for the majority of families attending a SIC in Australia, with selective immunization the most common outcome. Tailored communication approaches based on parental position on immunization may optimise clinic resources and engagement of families, but require prospective research evaluation.
