Are children with special risk medical conditions receiving influenza vaccination? Validity of parental and provider report, and to a National Immunisation Register.
To investigate the validity of parent reported influenza vaccination and provider reporting to the Australian Immunisation Register (AIR) in children with special risk medical conditions (SRMC). ⋯ Parental report over estimates confirmed influenza vaccination status and is affected by time and relationship to the child. Only a third of influenza vaccinations were reported to the AIR. Timely accurate data is critical to facilitate vaccination and evaluate program coverage.

Estimating the epidemiological impact and cost-effectiveness profile of a nonavalent HPV vaccine in Spain.
Human papillomavirus (HPV) is one of the main causes of infection-related cancer. The bivalent vaccine (2vHPV) (16/18) and quadrivalent (6/11/16/18) HPV vaccine (4vHPV) have been included in the Spanish vaccination calendar since 2007. The new nonavalent HPV vaccine (9vHPV), approved in Europe in 2015, includes nine HPV types 6/11/16/18/31/33/45/52/58 and has been available in Spain since May 2017. ⋯ A girls-only vaccination strategy at age 12 years with 9vHPV was found to be a cost-effective strategy compared with 4vHPV (incremental cost-effectiveness ratio (ICER) of €7,718 per QALY). Compared with girls-only vaccination with 4vHPV, gender-neutral vaccination with 9vHPV was associated with further reductions of up to 28.5% in the incidence of cervical intraepithelial neoplasia (CIN) 2/3 and 17.1% in the incidence of cervical cancer, as well as with a 14.0% reduction in cervical cancer mortality. Furthermore, a gender-neutral vaccination program with 9vHPV could potentially be cost-effective considering some parameters as head and neck protection or discount rates, leading to a reduction in the burden of HPV-related diseases in both sexes in the Spanish population.

Vaccine discussions in pregnancy: interviews with midwives to inform design of an intervention to promote uptake of maternal and childhood vaccines.
Presumptive and Motivational Interviewing communication styles have successfully promoted childhood and adolescent vaccination to parents, but less is known about effective communication approaches during pregnancy to promote maternal vaccination and childhood vaccines. In Australian public antenatal settings, midwives provide a substantial proportion of care and are highly accessed and trusted sources of vaccine information for expectant parents. However, there are no evidence-based interventions incorporating communication strategies and resources for midwives to optimize discussions and promote acceptance of maternal and childhood vaccines. ⋯ Their communication practices focused primarily on vaccine information provision rather than persuasion, although some midwives shared personal views and actively encouraged vaccination. More vaccine and communication training and resources were requested. Findings highlight the need for communication tools that align with midwifery standards for practice to support midwives to address parents' questions and concerns about maternal and childhood vaccines.

ReviewCurrent issues facing the introduction of human papillomavirus vaccine in China and future prospects.
The introduction of human papillomavirus (HPV) vaccination in China aims to prevent HPV infection in all women. The issues that China might face include high cost of vaccines made in other countries, shortage in HPV vaccine supply, negative events attributed to vaccination (whether justified or not) that jeopardizes the general public's confidence in the HPV vaccine, cultural and literacy barriers, and sensitivity to receiving a vaccine for a sexually transmitted disease. ⋯ New evidence supporting the efficacy of a two-dose regime in younger adolescents would also be advantageous in terms of affordability and logistical simplicity of vaccine administration. Furthermore, it would potentially enhance the compliance and uptake, especially for hard to reach women in remote regions.

Comparative StudyInfluenza vaccination in health-care workers: an evaluation of an on-site vaccination strategy to increase vaccination uptake in HCWs of a South Italy Hospital.
Despite the international recommendation and specific programs, and although the vaccination of health-care workers (HCWs) is considered the main measure to prevent nosocomial influenza, vaccination coverage (VC) among HCWs remains low. One of the most important barriers to vaccination uptake is the time required to attend a vaccination clinic. Centers for Disease Control and Prevention (CDC) recommends on-site influenza vaccination as a proven and cost-effective strategy that increases productivity, reduces overall absenteeism and prevents direct health-care costs. ⋯ VC in OUs target of on-site vaccination increased between 2016/17 and 2017/18 seasons of 16.8 ± 10.4% (range: 5.5-37.1), while the coverage in OUs of the control group increased of 1.6 ± 2.2% (range: -1.7-4.5), with a significant difference (p < .05). Our study suggests that the offer of on-site vaccination during the 2017/18 season led to an increase of VC in HCWs compared to the classical vaccination clinic approach. The determinants of adhesion and not-adhesion must be analyzed in dept, to experiment, in the future, new good clinical practices to increase the vaccination coverage in HCWs.
