Factors contributing to suboptimal rates of childhood vaccinations in Vermont

Resources for assessing parents' vaccine hesitancy: a systematic review of the literature

The concept of Vaccine Hesitancy has begun to appear in the scientific landscape, referring to the reluctance of a growing proportion of people to accept the vaccination offer. A variety of factors were identified as being associated with vaccine hesitancy but there was no universal algorithm and currently there aren’t any established metrics to assess either the presence or impact of vaccine hesitancy. The aim of this study was to systematically review the published questionnaires evaluating parental vaccine hesitancy, to highlight the differences among these surveys and offer a general overview on this matter. This study offers a deeper perspective on the available questionnaires, helping future researches to identify the most suitable one according to their own aim and study setting.

Knowledge influences attitudes toward vaccination in Romania

Despite proven effectiveness and safety of vaccinations, immunization rates are decreasing across Europe, most countries having suboptimal vaccination coverage, leading to an increase in the number of cases of preventable contagious diseases. In recent years, the number of parents who have refused to vaccinate their children in Romania has decreased substantially, while the number of fatal complications due to measles outbreak is one of the highest in Europe. Since healthcare professionals have been identified as the main advocates for immunization, knowledge and attitudes of medical students and nurses is of particular interest. A cross-sectional survey was carried out on 278 participants, divided into three groups: 183 medical students, 54 nurses and 41 non-medical professionals. The questionnaire included questions on demographics of participants, personal experience with vaccines, knowledge and attitude toward vaccination. The data was collected, centralized and analyzed using statistical methods. The survey was given to the medical students at the beginning of the Immunology course and again at the end, to test whether information received influenced their responses. The study revealed that a great majority of participants were themselves vaccinated [N=262 (94%)] and had/or would vaccinate their children [N=247 (95%)]. Satisfactory overall knowledge about effectiveness and safety concerns was observed, with 98% (N=270) considering vaccines as useful and over 96% (N=276) correctly identified their usefulness. When asked about adverse effects, concerning numbers [N=32, (19%)] of medical students answered incorrectly. After the Immunology course, however, there was significant improvement in knowledge on this topic (P<0.001), correlating with a positive shift in attitude towards current and future vaccines. We predict that better knowledge about vaccines, their efficacy and safety would help build the health provider's confidence in recommending vaccination and thus increased coverage rates.

Parental conceptions of the rotavirus vaccine during implementation in Stockholm: A phenomenographic study

In 2014, Stockholm became the first Swedish county to introduce the rotavirus vaccine, which is given from as early as six weeks of age. The aim of this study was to describe parental conceptions of rotavirus infection and vaccination during its implementation as part of the child immunization program, as their support is vital for any new vaccine. The study followed a descriptive, qualitative design with a phenomenographic approach. Ten in-depth interviews with parents were conducted in Stockholm County, transcribed and analyzed to describe qualitatively different conceptions of rotavirus infection and vaccination. Four main categories were identified: to vaccinate without doubt, hesitant to vaccinate, risky to vaccinate, and unnecessary to vaccinate. All the parents had in common the desire to protect their children from suffering, either by vaccinating their child in order to avoid rotavirus infection or by not vaccinating their child because of concerns about the side effects. It is important that child health-care professionals understand the variations of conceptions that influence the parents' decisions and that these conceptions may differ considerably. Individualized parental information about rotavirus infection and vaccination would help to achieve a successful implementation of the vaccination program.
