“…A second possible reason why reminder/education, ie, the “low‐intensity school intervention,” did not raise vaccination rates is that perhaps reminder/education about influenza vaccination emanating by email from schools might somehow “backfire” and increase parental hesitancy to vaccinate. We know that vaccine hesitancy is related to (1) lack of understanding of influenza disease and its potential consequences, (2) fear of vaccine side effects despite a strong safety record of influenza vaccine, and (3) skepticism of vaccine effectiveness . Our educational infographics message (see Supplemental Figure) included perceived susceptibility, influenza disease severity, benefit of vaccine, and cues to action, all components of the Health Belief Model, designed to both inform parents in a non‐threatening manner and educate about the disease and vaccine, and used in many school‐based interventions .…”

BACKGROUND: Only half of US schoolchildren receive influenza vaccine. School-located influenza vaccination (SLIV) might raise vaccination rates but conducting flu vaccine clinics at schools is challenging to implement. We compared 2 school-based programs designed to raise influenza vaccination rates: parent reminder/educational messages sent to parents from schools which is a low-intensity intervention vs the combination of reminder/educational messages plus SLIV clinics which is a high-intensity intervention. METHODS:We assigned 36 schools (6 school districts, 2 per group) to 3 groups: (1) control, ie, no SLIV and no parent reminder/education, (2) parent reminder/education emailed by schools, and (3) parent reminder/education plus SLIV clinics. Some schools had SLIV clinics in prior years. Health department nurses conducted SLIV clinics. RESULTS:Among 24,832 children at 36 schools, vaccination rates were control (51.3%), parent reminder/education-only (41.2%), and reminder/education + SLIV (58.7%). On multivariate analyses which controlled for vaccination in prior seasons, children in reminder/education + SLIV schools had higher vaccination rates (OR 1.27, 95% CI 1.10-1.47), but children in reminder/education-only schools had lower rates (OR 0.87, 95% CI 0.75-1.00) than children in control schools. CONCLUSIONS:Parent reminder/education combined with SLIV clinics raise vaccination rates, but parent reminder/education alone does not.

“…We retrieved a total of 6,277 studies. After removal of duplicates and screening of titles and abstracts, 22 full texts remained, of which 16 were included in the narrative synthesis [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] (see Figure 1). The main features of the included studies are summarized in Table 1.…”

“…All studies were conducted in western nations, with the exception of one conducted in Japan 32 and one in Malaysia. 36 Most quantitative studies made use of an ad hoc questionnaire specifically developed for the purpose of the research project, although three of them 36,37,40 used a version of the questionnaire developed by Opel et al for the Parent Attitudes and Childhood Vaccines (PACV) survey, 45,46 which was adapted for pregnant women. The original PACV survey was self-administered and contained 15 items in three domains (behavior, safety and efficacy, and general attitudes), and in the three studies cited it was slightly modified to include specific items relating to expectant mothers.…”

“…38 In a multivariate analysis, Mohd Azizi et al found that pregnant mothers expecting their first child were four times more likely to be vaccinehesitant than those who already had one or more children. 37 Factors associated with vaccine hesitancy in the study by Cunningham et al included holding a college level of education or less, compared with holding more than a four-year degree and not receiving an annual influenza vaccine. 38 The importance of vaccination in protecting individuals and the community against infectious diseases was acknowledged by most pregnant women included in those studies that assessed this issue.…”

In recent years, an increase in vaccine hesitancy has led to a decrease in vaccination coverage in several countries. We conducted a systematic review of studies that assessed knowledge of and attitudes toward pediatric vaccinations, and the vaccination choices and their determinants among pregnant women. A total of 6,277 records were retrieved, and 16 full texts were included in the narrative synthesis. The published literature on the topic shows that, overall, pregnant women believe that vaccines are important for the protection of their children and the community, but various concerns and misunderstandings persist around vaccine safety and efficacy, which reduce the trust of expectant mothers in immunization. Nevertheless, such attitudes and choices vary depending on the vaccine being considered and the corresponding determinants should therefore be studied in the context of each specific vaccination. Further research on this topic is needed, particularly in non-western countries.

“…The most commonly used standard questionnaire was the Parent Attitudes about Childhood Vaccines (PACV) Survey Tool, used in 4 studies with its full format with 15 questions (15)(16)(17)(18). In some studies, the PACV questions were adapted to match the local context or study population, such as in Malaysia (17) and for expectant parents in the United States (15). In 2 studies, a subset of the PACV questions were used (19,20).…”

Background Acceptance of vaccines is an important predictor of vaccine uptake. This has public health implications as those who are not vaccinated are at a higher risk of infection from vaccine preventable diseases. We aimed to systematically review studies of parental attitudes and beliefs in childhood vaccination, with a focus on the methods used to measure hesitancy and refusal.Methods We identified and reviewed primary research studies using quantitative methods and investigating vaccine attitudes and beliefs published between January 2012 and May 2018. Studies were included if they involved a quantitative survey of the attitudes and beliefs of parents about vaccinations recommended for children. We undertook a narrative synthesis of the results with a focus on evaluating variation in the use of behavioural theories, validated survey instruments, and localisation and adaptation of questions to suit local context.Results A total of 116 studies met the inclusion criteria; 99 used a cross sectional study design, 5 used a case control study design, 4 used a pre-post study design and 8 used mixed methods study designs. Sample sizes of included studies ranged from 49 to 12,259. Thirty-six countries were represented in the included studies. The most commonly used tool was the Parent Attitudes about Childhood Vaccines (PACV) Survey. Questions eliciting vaccination attitudes and beliefs varied widely.Conclusions There was heterogeneity in the types of measures used in studies investigating attitudes and beliefs about vaccination in parents. Broader and more consistent use of validated survey instruments for measuring parental attitudes and beliefs about childhood vaccination would help to better understand localised differences in the reasons for vaccine hesitancy and refusal.
