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.

Randomized Controlled TrialLong-term immunogenicity and safety of tetravalent dengue vaccine (CYD-TDV) in healthy populations in Singapore and Vietnam: 4-year follow-up of randomized, controlled, phase II trials.
Dengue is prevalent in the Asia-Pacific region. Participants of two immunogenicity and safety phase II studies conducted in Singapore and Vietnam (NCT0088089 and NCT00875524, respectively) were followed for up to four years after third vaccine dose of a recombinant, live, attenuated, tetravalent dengue vaccine (CYD-TDV). Participants (2-45 years) received three doses of CYD-TDV or control at 0, 6, and 12 months. ⋯ Seropositivity rates were higher at year four in participants who were seropositive vs. seronegative at baseline in both studies. No safety concerns were identified. CYD-TDV demonstrated long-term immunogenicity and was well-tolerated for four years after the third vaccine dose.

Determinants of vaccine hesitancy in Quebec: a large population-based survey.
Objectives: Vaccine hesitancy is a global phenomenon that needs to be measured and addressed. This study aimed to identify the determinants of vaccine hesitancy among a large regional population. Methods: A structured telephone survey was administered to a random digit sample in Quebec's Eastern Townships region. ⋯ Other determinants associated with vaccine hesitancy were having consulted a massage therapist (aOR = 2.34; 1.46-3.75), not being vaccinated against influenza (aOR = 1.80; 1.49-2.16), having a low (<$30,000) (aOR = 1.58; 1.24-2.02) or moderate ($30,000-$79,000) (aOR = 1.37; 1.12-1.67) household income, distrust in public health authorities (aOR = 1.40; 1.21-1.63), perceived insufficient knowledge about immunization (aOR = 1.26; 1.04-1.51), and smoking (aOR = 1.22; 1.01-1.47). Conclusions: Many determinants are related to vaccine hesitancy. These determinants should be taken into account when health professionals engage with vaccine-hesitant individuals.

Improving influenza vaccination uptake among healthcare workers by on-site influenza vaccination campaign in a tertiary children hospital.
Children are at higher risk of influenza complications. The goals of this article are, estimating influenza vaccination coverage of Health Care Workers (HCWs) in tertiary children hospital, evaluating attitudes and practices of HCWs and evaluating whether HCWs vaccination uptake improved with onsite vaccination campaign. This was a before-after trial, which was carried out in a tertiary children hospital at 2017-2018 influenza season. ⋯ After onsite vaccination campaign, influenza vaccination coverage improved significantly among HCWs. In order to achieve target vaccination coverage we should break down the prejudices with a comprehensive education program. Abbreviations: OR- Odds ratio; CI- confidence interval.

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.
