Understanding the Factors Influencing Health Care Provider Recommendations about Adolescent Vaccines: A Proposed Framework.

Health care provider recommendations are among the most important factors influencing parents' decisions to vaccinate their adolescents. However, delivery of high-quality health care provider recommendations for vaccination is not universal. There is wide variation in the strength, timeliness and consistency of the delivery of recommendations for all adolescent vaccines. The factors that influence health care providers' recommendations are multi-level and can be conceptualized in much the same way as vaccine acceptance among parents. Health care providers are influenced by their own attitudes and beliefs about a vaccine and also by the patient they are treating and by the community in which they practice as well as state and national level vaccine policy. We propose a multi-level framework for understanding the factors that influence health care providers' recommendations at the individual, interpersonal and community level to both develop and adapt interventions to improve providers' recommendations.

February 2023 Updates of the Advisory Committee on Immunization Practices.

The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts who provides expert advice to the Centers for Disease Control and Prevention, normally meets three times per year to develop U.S. vaccine recommendations. The ACIP met on February 22-24, 2023, to discuss mpox vaccine, influenza vaccines, pneumococcus vaccines, meningococci vaccines, polio vaccines, respiratory syncytial virus (RSV) vaccine, chikungunya vaccines, dengue vaccines, and COVID-19 vaccines.

Coronavirus Disease-2019 Vaccine Hesitancy.

Early in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, before coronavirus disease-2019 (COVID-19) vaccines were authorized, surveys began tracking public acceptance of a hypothetical COVID-19 vaccine. As vaccines became more widely available, the focus shifted from evaluating premeditative thoughts about COVID-19 vaccines to observing behaviors, measuring uptake, and characterizing factors associated with acceptance. A wealth of peer-reviewed literature examining the complexities of COVID-19 vaccine acceptance has emerged, but our understanding of COVID-19 vaccine acceptance is constantly evolving. In this article, we review the current state of knowledge regarding COVID-19 vaccine hesitancy, with an emphasis on pediatric vaccination.

Development of PIVOT with MI: A motivational Interviewing-Based vaccine communication training for pediatric clinicians.

Delay or refusal of childhood vaccines is common and may be increasing. Pediatricians are parents' most trusted source for vaccine information, yet many struggle with how to communicate with parents who resist recommended vaccines. Evidence-based communication strategies for vaccine conversations are lacking. In this manuscript, we describe the development and perceived usefulness of a curriculum to train clinicians on a specific vaccine communication strategy as part of the PIVOT with MI study, a cluster randomized trial testing the effectiveness of this communication strategy on increasing childhood vaccination uptake among 24 pediatric practices in Colorado and Washington. The communication strategy is based on the existing evidence-based communication strategies of a presumptive format for initiating vaccine conversations and use of motivational interviewing if hesitancy persists. Focus groups and semi-structured interviews with pediatric clinicians helped inform the development of the training curriculum, which consisted of an introductory video module followed by 3 training sessions. Between September 2019 and January 2021, 134 pediatric clinicians (92 pediatricians, 42 advanced practice providers) participated in the training as part of the PIVOT with MI study. Of these, 92 % viewed an introductory video module, 93 % attended or viewed a baseline synchronous training, 82 % attended or viewed a 1st refresher training, and 77 % attended or viewed a 2nd refresher training. A follow-up survey was administered August 2020 through March 2021; among respondents (n = 100), >95 % of participants reported that each component of the training program was very or somewhat useful. These data suggest that the PIVOT with MI training intervention is a useful vaccine communication resource with the potential for high engagement among pediatric clinicians.

Update From the September 2022 Meeting of the Advisory Committee on Immunization Practices.

The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts that provides expert advice to the Centers for Disease Control and Prevention (CDC), normally meets three times per year to develop US vaccine recommendations. The ACIP increased their meeting frequency over the past 2.5 years to address vaccine-related issues during the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic. They met to discuss updating COVID-19 booster dose recommendations on September 1, 2022 recommending use of new bivalent Coronavirus Disease-2019 (COVID-19) booster vaccines which include equal amounts of ancestral and Omicron BA.4/BA.5 variant mRNA that encodes the spike protein.

Rural parents' attitudes and beliefs on the COVID-19 pediatric vaccine: An explanatory study.

The coronavirus disease 2019 (COVID-19) first came to the Unites States in January 2020. Though adult and pediatric vaccines became available to the public, vaccine uptake among youth and particularly younger children has been gradual. This explanatory study aimed to better understand parents' attitudes and beliefs of the pediatric COVID-19 vaccine and the barriers and facilitators to vaccine uptake in a rural community through a brief, online demographic survey, and in-depth qualitative interviews. Forty-one in depth interviews were conducted with parents (31-English and 10-Spanish-speaking) residing in rural and frontier counties in Colorado between September 2021 and February 2022. Six emergent themes related to COVID-19 pediatric vaccine uptake were identified among the population. These themes spanned the three levels of influence in the Social Ecological Model (individual, interpersonal, and community levels). The six themes were identified as such; 1) Vaccine accessibility was associated with pediatric COVID vaccine uptake in rural communities, 2) Previous pediatric vaccine behaviors were not associated with COVID-19 pediatric vaccine uptake, 3) Perceived health status of a child or family member influenced pediatric COVID-19 vaccine uptake, 4) COVID-19 health seeking behaviors, like COVID pediatric vaccine uptake, are influenced by an individual's prosocial or individualistic perspectives, 5) Child autonomy and "age of consent" frames vaccine decision making behaviors in parents, and lastly 6) Social networks impacted COVID-19 pediatric vaccine decision making. These findings inform next steps for COVID-19 pediatric vaccine uptake including targeted and tailored messaging for communities (cues to actions), engaging youth stakeholders, and identifying trusted sources to build rapport and trust between health professionals and community members. The growing vaccine hesitancy among parents has serious implications for disease eradication and future viral outbreaks. Understanding the perceived barriers and facilitators to pediatric vaccine uptake is important to maintain the health of our youth and communities.

COVID-19 Vaccine Acceptance Among US Parents: A Nationally Representative Survey.

BACKGROUND: Little was known about US parental attitudes, beliefs, and intentions surrounding coronavirus disease 2019 (COVID-19) vaccines for children before their introduction. METHODS: An online cross-sectional nationally representative survey of US parents/guardians of children < 18 years old via Ipsos KnowledgePanel, fielded from October 26, 2021 to November 30, 2021. RESULTS: Response rate was 64.2% (3230/5034). For children ages 0-4 years, 51.5% of parents were likely to have their children vaccinated, and for ages 5-11 and 12-17, 54.0% and 69.7% of parents, respectively, reported they were likely to vaccinate or had already vaccinated their children. Among respondents with unvaccinated children, 25.2% (ages 0-4) and 22.0% (ages 5-11) reported they would seek COVID-19 vaccination for their children as soon as authorization occurred. Factors associated with willingness to have children receive a COVID-19 vaccine were: belief in benefits of COVID-19 vaccination (odds ratio [OR] = 6.44, 5.68, 4.57 in ages 0-4, 5-11, and 12-17 respectively), acceptance of routine childhood vaccines (OR = 6.42, 5.48, 1.76), parental COVID-19 vaccination (OR = 1.85, 3.70, 6.16), perceptions that pediatric COVID-19 is severe (OR = 1.89, 1.72, 1.35), Hispanic ethnicity (OR = 2.07, 2.29, 2.60), influenza vaccine acceptance (OR = 1.07, 0.88, 1.62), presence of children of another age group in the household (OR = 0.71, 0.71, 0.65), and attitudinal barriers to COVID-19 vaccination (OR = 0.30, 0.26, 0.49). CONCLUSIONS: Belief in the benefits of COVID-19 vaccination and acceptance of routine childhood vaccines are the strongest predictors of intention to vaccinate children. Further research is needed to track how parental attitudes change as more data about pediatric COVID-19 vaccines become available and how intentions translate into pediatric vaccine uptake.

US Primary Care Providers' Experiences and Practices Related to Routine Pediatric Vaccination During the COVID-19 Pandemic.

OBJECTIVE: To describe, among pediatricians (Peds) and family physicians (FPs), 1) changes made to routine childhood vaccination delivery as a result of the pandemic, and 2) perceived barriers to delivering vaccinations from March 2020 through the time of the survey. METHODS: A nationally representative survey among Peds and FPs was administered by mail or Internet in October-December 2020. RESULTS: Response rate was 64% (579/909). For children aged 0 to 2 years, among those who vaccinated that age group prepandemic (Peds n = 265, FPs n = 222), 5% of Peds and 15% of FPs reported they had stopped vaccinating these children at any time. For children aged 4 to 6 years (Peds n=264, FPs n = 229), 19% of Peds and 17% of FPs reported they had stopped vaccinating at any time. For children aged 11-18 years (Peds n = 265, FPs n = 251), 24% of Peds and 19% of FPs reported they had stopped vaccinating at any time. Nearly all reported returning to prepandemic vaccination services at the time of the survey. Factors most frequently reported as major/moderate barriers to providing vaccinations included fewer in-person visits because patients/parents were concerned about risk of SARS-CoV-2 infection (Peds, 52%; FPs, 54%), fewer in-person visits for sports clearance (Peds, 39%; FPs, 44%), and fewer back-to-school in-person visits because some children were in virtual learning (Peds, 25%; FPs, 33%). CONCLUSIONS: Although some physicians reported interrupting vaccination services at some point during the pandemic, the majority reported continuing to provide vaccinations throughout, with essentially all returning to prepandemic vaccination services by end of 2020.

The Risk of Resurgence in Vaccine-Preventable Infections Due to Coronavirus Disease 2019-Related Gaps in Immunization.

Nationally, immunization delivery has decreased significantly during the coronavirus disease 2019 (COVID-19) pandemic. Internationally, >60 national vaccine programs have been disrupted or suspended. As a result of these immunization declines, the global community is at risk for a resurgence in vaccine-preventable infections including measles, pertussis, and polio-all highly contagious diseases that result in significant morbidity and mortality in children. Measles outbreaks have already occurred in many countries that suspended their vaccination programs. Outbreaks in the United States are likely to occur when social distancing stops and children return to school. Healthcare providers have acted quickly to institute multiple risk mitigation strategies to restore vaccine administration. However, childhood immunization rates remain below pre-COVID-19 levels. Partnerships between healthcare providers, community leaders, and local, state, regional, and national public health departments are needed to reassure families that vaccine delivery during COVID-19 is safe and to identify and catch up those children who are underimmunized.

Associations between religion, religiosity, and parental vaccine hesitancy.

INTRODUCTION: Religious vaccine exemptions are widely available and increasing despite decreases in American religiosity. We tested associations between religion, religiosity, and caregiver vaccine hesitancy in a sample of caregivers of 2-year-olds. METHODS: We analyzed data from a 2020 survey in three pediatric clinics, estimating distinct multivariable logistic regression models to examine associations. RESULTS: Our sample included 255 predominantly poor, Latino, Christian, and English-speaking caregivers (response rate: 90%); 13% were vaccine hesitant. Caregivers identifying with major faith traditions were not more likely to be hesitant than those without a tradition (adjusted odds ratio 1.46; 95% CI 0.29, 7.26). There were no significant associations between caregiver vaccine hesitancy and three religiosity domains. CONCLUSIONS: We found no associations between parental vaccine hesitancy, religiosity, or adherence to a major faith tradition in a sample of mostly poor, Latino, Christian mothers. Additional work is needed to inform exemption policies and public health and faith leaders.

Addressing Vaccine Concerns: A Hopeful Path Forward for Vaccine Confidence

Health care providers and public health professionals are the most trusted sources of vaccine information for most people and as such have the potential to play an important role in addressing misinformation. PRINCIPLES TO ADDRESS MISINFORMATION AND BOOST CONFIDENCE After understanding motivation, context, and audience, medical and public health professionals can apply several principles to address vaccine misinformation and strengthen vaccine confidence.

Update From the Advisory Committee on Immunization Practices.

The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts, normally meets 3 times per year to develop recommendations for vaccine use in the United States. Because of the severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) pandemic, there are several SARS-CoV-2 vaccines currently in late-stage clinical trials, so the ACIP is now meeting monthly for single day meetings, with plans to continue standard 2- to 3-day meetings as per usual (February, June, and October). Emergency meetings of ACIP may occur if a vaccine candidate receives an Emergency Use Authorization from the food and drug administration (FDA). This Update provides a combined summary of the August 26 and September 22, 2020, meetings, both of which focused completely on Coronavirus disease 2019 (COVID-19) vaccines. The representatives from the American Academy of Pediatrics (Y. A. M. and D. W. K.) and the Pediatric Infectious Diseases Society (S. T. O.) are present as liaisons to the ACIP.
