Office-Based Educational Handout for Influenza Vaccination: A Randomized Controlled Trial

The Effect of a Quality Improvement Project on Improving Patients' Willingness to Receive an Influenza Vaccination in the Emergency Department

The aim of this project was to increase willingness to receive the influenza vaccine to the optimal rate of ≥ 70%. Low acuity adult patients who visited an Emergency Department (ED) were assessed regarding their willingness to receive the influenza vaccine before and after an educational intervention that included a provider recommendation and an educational handout. A total of seventy-six patients (n = 76) were assessed. Patients' willingness to receive the influenza vaccine rose from 29% pre-intervention to 72% post-intervention without disrupting the clinical flow in a busy ED. Similar vaccine educational strategies can be applied to influenza and other vaccines in EDs  to increase vaccination willingness in patients, including those who use the ED as a primary point of contact for healthcare, decreasing the burden of influenza illness in the community.

Strategies for Improving Vaccine Communication and Uptake

Vaccines have led to a significant decrease in rates of vaccine-preventable diseases and have made a significant impact on the health of children. However, some parents express concerns about vaccine safety and the necessity of vaccines. The concerns of parents range from hesitancy about some immunizations to refusal of all vaccines. This clinical report provides information about the scope and impact of the problem, the facts surrounding common vaccination concerns, and the latest evidence regarding effective communication techniques for the vaccine conversation. After reading this clinical report, readers can expect to: Understand concepts and underlying determinants of vaccine uptake and vaccine hesitancy.Understand the relationship between vaccine hesitancy and costs of preventable medical care.Recognize and address specific concerns (eg, vaccine safety) with caregivers when hesitancy is present.

Declining influenza vaccination rates in an underserved pediatric primary care center during the COVID-19 pandemic

BACKGROUND

Influenza vaccination rates are decreasing in the United States. Disinformation surrounding COVID-related public health protections and SARS-CoV-2 vaccine roll-out may have unintended consequences impacting pediatric influenza vaccination.We assessed influenza vaccination rates before and during the COVID-19 pandemic in one pediatric primary care center, serving a minoritized population.

METHODS

A cross-sectional study assessed influenza vaccination rates for children aged 6 months to 12 years over the following influenza seasons (September-May): 1) 2018-19 and 2019-20 (pre-pandemic), and 2) 2020-21 and 2021-22 (intra-pandemic). Demographics and responses to social risk questionnaires were extracted from electronic health records. Total tetanus vaccinations across influenza seasons served as approximations of general vaccination rates. Generalized linear regression models with robust standard errors evaluated differences in demographics, social risks, and influenza vaccination rates by season. Multivariable logistic regression with robust standard errors evaluated associations between influenza season, demographics, social risks, and influenza vaccination.

RESULTS

Most patients were young (mean age ∼ 6 years), non-Hispanic Black (∼80%), and publicly insured (∼90%). Forty-two percent of patients eligible to receive the influenza vaccine who were seen in 2019-20 influenza season received the influenza vaccine, compared to 30% in 2021-22. Influenza and tetanus vaccination rates decreased during the COVID-19 pandemic (p < 0.01). The 2020-21 and 2021-22 influenza seasons, older age, Black race, and self-pay were associated with decreased influenza vaccine administration (p < 0.05).

CONCLUSIONS

Influenza vaccination rates within one pediatric primary care center decreased during the COVID-19 pandemic and have not rebounded, particularly for older children, those identifying as Black, and those without insurance.

Recommendations for Prevention and Control of Influenza in Children, 2022-2023

This technical report accompanies the recommendations of the American Academy of Pediatrics for the routine use of influenza vaccine and antiviral medications in the prevention and treatment of influenza in children during the 2022 to 2023 season. The American Academy of Pediatrics recommends annual influenza vaccination of all children without medical contraindications starting at 6 months of age. Influenza vaccination is an important strategy for protecting children and the broader community as well as reducing the overall burden of respiratory illnesses when other viruses, including severe acute respiratory syndrome-coronavirus 2, are cocirculating. This technical report summarizes recent influenza seasons, morbidity and mortality in children, vaccine effectiveness, and vaccination coverage, and provides detailed guidance on storage, administration, and implementation. The report also provides a brief background on inactivated and live attenuated influenza vaccine recommendations, vaccination during pregnancy and breastfeeding, diagnostic testing, and antiviral medications for treatment and chemoprophylaxis. Updated information is provided about the 2021 to 2022 influenza season, influenza immunization rates, the effectiveness of influenza vaccination on hospitalization and mortality, available vaccines, guidance for patients with history of severe allergic reactions to prior influenza vaccinations, and strategies to promote vaccine uptake.

Factors Associated With Parental COVID-19 Vaccination Acceptance

As the coronavirus pandemic continues to impact families and children, understanding parental attitudes and likely acceptance of the COVID-19 vaccine is essential. We conducted a statewide survey with a representative sample of parents in Tennessee focused on COVID-19 and influenza vaccine acceptance and perspectives. Data from 1066 parents were analyzed using weighted survey methods to generalize results to the state of Tennessee. About 53% of parents reported a likelihood to vaccinate their children against COVID-19, and 45% were likely to vaccinate their child against COVID-19 and influenza. Female parents were less likely to vaccinate their children against COVID-19, but the strongest predictor of likely COVID-19 vaccine acceptance was influenza vaccine acceptance (adjusted odds ratio = 5.46; 95% confidence interval: 3.20-9.30). Parental acceptance of COVID-19 vaccines for children is closely tied to influenza vaccine acceptance. Public health approaches to maximize vaccine uptake could focus on children who have not been receiving influenza vaccines.

Interventions to Improve Immunization Coverage Among Children and Adolescents: A Meta-analysis

BACKGROUND AND OBJECTIVES

Vaccinations are recognized as a feasible, cost-effective public health intervention for reducing the burden and associated mortality of many infectious diseases. The purpose of this study was to evaluate the effectiveness of potential interventions to improve the uptake of vaccines among children and adolescents.

METHODS

We performed a literature search until December 2020. Eligible studies were identified using Cochrane Central Register of Controlled Trials, MEDLINE, PubMed, and other sources. We included studies conducted on children and adolescents aged 5 to 19 years. Studies comprised of hospitalized children and those with comorbid conditions were excluded. Two authors independently performed the meta-analysis.

RESULTS

Findings from 120 studies (123 articles), of which 95 were meta-analyzed, reveal that vaccination education may increase overall vaccination coverage by 19% (risk ratio [RR], 1.19; 95% confidence interval [CI], 1.12-1.26), reminders by 15% (RR, 1.15; 95% CI, 1.11-1.18), interventions for providers by 13% (RR, 1.13; 95% CI, 1.07-1.19), financial incentives by 67% (RR, 1.67; 95% CI, 1.40-1.99), and multilevel interventions by 25% (RR, 1.25; 95% CI, 1.10-1.41). The impact of school-based clinics and policy and legislation on overall vaccination coverage is still uncertain, and no impact of a multicomponent intervention on overall vaccination coverage was found.

CONCLUSIONS

Educational interventions, reminders, provider-directed interventions, financial incentives, and multilevel interventions may improve vaccination coverage among school-aged children and adolescents.

Shifting the Demand for Vaccines: A Review of Strategies

Vaccines prevent millions of deaths, and yet millions of people die each year from vaccine-preventable diseases. The primary reason for these deaths is that a significant fraction of the population chooses not to vaccinate. Why don't people vaccinate, and what can be done to increase vaccination rates besides providing free and easy access to vaccines? This review presents a conceptual framework, motivated by economic theory, of which factors shift the demand for vaccines. Next, it critically examines the literature on these demand shifters and interventions that target these demand shifters. The review concludes with offering directions for future research and lessons for public health decision-making. Expected final online publication date for the Annual Review of Public Health, Volume 43 is April 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Parental COVID-19 vaccine hesitancy: a cross-sectional survey in Italy

BACKGROUND

Understanding parents' hesitancy against COVID-19 vaccination for their children is useful.

METHODS

A self-administered online survey was conducted among 394 parents with at least one child aged 12-18 years in Italy.

RESULTS

The mean perceived risk that their child can be infected by the SARS-CoV-2, measured on a 10-point Likert-type scale, was 7.7 and it was higher if at least one parent/partner cohabitant have had COVID-19, in those who believed that COVID-19 is a serious illness, and in those who had not vaccinated their child. 82.1% respondents were willing to vaccinate their child and this was more likely among those who believed that this vaccine is useful and who did not need additional information. 12.4% were, according to the 5-item Parent Attitudes About Childhood Vaccines Survey (PACV-5) score, high-hesitant toward anti-COVID-19 vaccination. Respondents not graduated, those who did not believe that this vaccination was useful, those who did not get this vaccine, those who did not obtain information from physicians, and those who needed additional information were more likely to be high-hesitant.

CONCLUSIONS

Communication and public health interventions must be intensified to enhance the attitude and to help parents in deciding on COVID-19 vaccination of their children.

A rapid global review of strategies to improve influenza vaccination uptake in Australia

This study aimed to identify effective strategies for improving the uptake of influenza vaccination and to inform recommendations for influenza vaccination programs in Australia. A rapid systematic review was conducted to assimilate and synthesize peer-reviewed articles identified in PubMed. The National Health and Medical Research Council (NHMRC) Hierarchy of Evidence was used to appraise the quality of evidence. A systematic search identified 4373 articles and 52 that met the inclusion criteria were included. The evidence suggests influenza vaccination uptake may be improved by interventions that (1) increase community/patient demand and access to influenza vaccine and overcome practice-related barriers; (2) reinforce the critical role healthcare providers play in driving influenza vaccination uptake. Strategies such as standing orders, reminder and recall efforts were successful in improving influenza vaccination rates. Community pharmacies, particularly in regional/remote areas, are well positioned to improve influenza vaccine coverage. The findings of this rapid review can be utilized to improve the performance of influenza immunization programs in Australia and other countries with comparable programs; and recommend priorities for future evaluation of interventions to improve influenza vaccination uptake.

Understanding parents' use of a knowledge translation tool to manage children's vaccination pain

Supplemental Digital Content is Available in the Text.

The relevance of KT tools, and parents' confidence in using them, was related to uptake of vaccination pain management strategies for children.

Introduction:

Although several evidence-based strategies for managing children's vaccination pain exist, many parents report being unaware of them. Knowledge translation (KT) tools present evidence-based information in plain language.

Objectives:

This two-phase study assessed parents/caregivers' uptake of evidence-based pain management strategies via a KT tool and considered factors related to parents' planned, actual, and future use of these strategies.

Methods:

In phase 1, parents were exposed to an online KT tool on physical, psychological, and pharmacological vaccination pain management strategies, and their impressions were assessed by questionnaires including the Information Assessment Method for Parents. In phase 2, after vaccination, parents completed a follow-up survey on their uptake and experiences using the information.

Results:

A total of 312 participants reported their plans for KT tool use. Parents who found the KT tool relevant were more likely to plan to use it at their child's upcoming vaccination. A total of 128 parents (93% mothers) completed both surveys. Nearly all parents who planned to use the information did so during their child's subsequent vaccination (90%). When the KT tool was relevant to their needs, parents were more likely to use the information during their child's vaccination. Parents who felt confident using the tool were significantly more likely to report plans for future tool use.

Discussion:

This study demonstrates the effectiveness of a KT tool that was relevant to parents' needs and built confidence to increase parent-reported uptake of evidence-based strategies. Proper pain management could positively impact parents' uptake of vaccinations for children.

Impact of an influenza information pamphlet on vaccination uptake among Polish pupils in Edinburgh, Scotland and the role of social media in parental decision making

BACKGROUND

In Edinburgh, Scotland, lower influenza vaccine uptake has been observed in primary school children in the Polish community.

METHODS

To address this disparity, the Polish-language version of the NHS Health Scotland influenza information pamphlet was updated and distributed in 2018 to all identified Polish pupils attending three pilot schools. The impact of the revised pamphlet was evaluated by examining changes in vaccine uptake in these schools as compared to a control group of schools, and a questionnaire was issued to all Polish parents in the pilot schools to explore their opinions of the pamphlet and preferred sources of immunisation information.

RESULTS

On average uptake was 7.4% (95% CI 1.0-13.8%, p < 0.05) higher in the three pilot schools in which the Polish-language pamphlet was distributed (28.7%) than control schools (21.3%). The questionnaire feedback was that 37.3% of respondents felt better-informed about the influenza vaccine following the pamphlet. The respondents reported that the most important information source in deciding whether to vaccinate is previous experience. Healthcare professionals were ranked lower in importance when making a decision. Parents, who refused consent (n = 65) were more likely to source information from social media, friends and family, and Polish websites compared with those who consented (n = 45).

CONCLUSIONS

These findings suggest that issuing new Polish health literature was associated with a large increase in consent form return rate and a modest increase in uptake of the influenza vaccine by Polish pupils in the pilot schools. Social media and Polish websites were found to have a greater influence over Polish parents' decision to immunise than UK healthcare staff and health authority information. Intensive effort is required to encourage parents towards information sources where more accurate pro-vaccination messages can be promulgated by national health services and independent expert groups. The role of social media for migrant communities requires careful consideration, especially for vaccine programmes not delivered in their country of birth.

Vaccine hesitancy and influenza beliefs among parents of children requiring a second dose of influenza vaccine in a season: An American Academy of Pediatrics (AAP) Pediatric Research in Office Settings (PROS) study

To receive adequate protection against influenza, some children 6 months through 8 y old need two doses of influenza vaccine in a given season. Currently, only half of those receiving the first dose receive a second. Our objective was to assess vaccine hesitancy and influenza disease and vaccine knowledge, attitudes, and beliefs among caregivers of children who received the first of their two needed doses. As part of a national-randomized control trial of second dose text-message influenza vaccine reminders (2017-2018 season), a telephone survey collected caregiver and index child demographic information. Each child had received the first of two needed influenza vaccine doses. Caregivers completed a measure of general vaccine hesitancy - the five-question Parent Attitudes About Childhood Vaccines Survey Tool (PACV-5) - and questions about influenza infection and vaccine. We assessed associations between participant demographic characteristics, vaccine hesitancy, and influenza beliefs and calculated the standardized proportion of caregivers endorsing each outcome using logistic regression. Analyses included responses from 256 participants from 36 primary care practices in 24 states. Some caregivers (11.7%) reported moderate/high vaccine hesitancy and many had misperceptions about influenza disease and vaccine. In multivariable models, no single variable was consistently associated with inaccurate knowledge, attitudes, and beliefs. These results demonstrate that caregivers whose children received the first dose of influenza vaccine may still be vaccine hesitant and have inaccurate influenza beliefs. Pediatricians should consider broadly addressing inaccurate beliefs and promoting vaccination even after caregivers agree to the first dose.
