Addressing Vaccine Hesitancy in the Age of COVID-19

Clinician Prompts for Human Papillomavirus Vaccination: A Cluster Randomized Trial

OBJECTIVE

We assessed the impact of an online intervention using clinician prompts for human papillomavirus (HPV) vaccination with a cluster randomized controlled trial.

METHODS

The randomized trial occurred July 2021-January 2022 in 48 primary care pediatric practices (24 intervention, 24 control) across the US. We trained clinicians via two online learning modules, plus weekly ''quick tips'' delivered via text or email. The training taught practices to implement a staff prompt to the clinician (e.g., printed reminders placed on the keyboard) plus electronic health record (EHR) prompts (if not already done) at well and acute/chronic visits for initial and subsequent HPV vaccination. We assessed missed opportunities for HPV vaccination using logistic regression models accounting for clustering by practice on an intent to treat basis. Surveys assessed facilitators and barriers to using prompts.

RESULTS

During the 6-month intervention, missed opportunities for HPV vaccination increased (worsened) in both intervention and control groups. However, at well child care visits, missed opportunities for the initial HPV vaccine increased by 4.5 (95% CI: -9.0%, -0.1%) percentage points less in intervention versus control practices. Change in missed opportunities for subsequent doses at well child care and non-well child care visits did not differ between trial groups. An end-of trial survey found understaffing as a common challenge.

CONCLUSIONS

Clinician prompts reduced missed opportunities for HPV vaccination at well child care visits. Understaffing related to the COVID-19 pandemic may have led to worsening missed opportunities for both groups and likely impeded practices in fully implementing changes.

Using Technology to Overcome Vaccine Hesitancy

Technology holds great potential to address many vaccine hesitancy determinants and support vaccine uptake given its ability to amplify positive messages, support knowledge, and enhance providers' recommendations. Modalities previously implemented with variable success have included automated reminder systems, decision support for clinicians, online education programs, social media campaigns, and virtual reality curricula. Further research is needed to identify the optimal uses of technology at the patient/parent and provider levels to overcome vaccine hesitancy. The most effective interventions will likely be multipronged providing patients, parents, and providers with information related to vaccine status.

State of Vaccine Hesitancy in the United States

Although the term "vaccine hesitancy" has achieved great prominence, the extent to which US parents have reluctance, doubts, or indecision when it comes to vaccines recommended for children and how such hesitancy is manifest are unclear. A narrative review approach that placed emphasis on recent data and published work is used to surface evidence and insights into the current state of US parent vaccine hesitancy. The assessment finds evidence that ∼6% to 25% of parents may be vaccine hesitant, that hesitancy is higher for influenza and HPV vaccines, and there are indications that addressing parent hesitancy has become more challenging.

Vaccine Attitudes Mediate Relationships Between Caregiver Political Ideology and Likelihood of Child Vaccination for COVID-19

INTRODUCTION

The COVID-19 vaccine has become available to children ages 5-12, yet vaccine uptake is suboptimal. Political ideology is a correlate of COVID-related beliefs and vaccine likelihood among US adults. However, since political ideology is not easily modifiable, attention to modifiable mechanisms that may explain links between political ideology and vaccine hesitancy is important in addressing this public health crisis. Caregiver attitudes around vaccine safety and efficacy have been related to vaccine uptake in other populations and warrant additional study in the context of COVID-19. The current study examined whether caregiver's attitudes regarding the safety and efficacy of the COVID-19 vaccine mediated the relationship between caregiver political ideology and likelihood of having their child vaccinated.

METHODS

144 US caregivers of children (6-12 years) completed an online survey in summer 2021 to assess political ideology, vaccine-related beliefs, and likelihood of having their child vaccinated against COVID-19.

RESULTS

Caregivers with more liberal political views reported higher likelihood of eventual child vaccination compared to caregivers who reported a more conservative views (t(81) = 6.08, BCa CI [2.97, 5.67]). Moreover, parallel mediation models indicated caregiver?s perceptions of risks (BCa CI [-.98, -.10]) and efficacy (BCa CI [-3.16, -2.15]) of the vaccine each mediated the aforementioned relationship, with perceived efficacy explaining significantly more variance than risks.

CONCLUSIONS

Findings extend knowledge by identifying social cognitive factors that impact caregiver vaccine hesitancy. Interventions to address caregiver's hesitancy to have their child vaccinated through modifying caregiver's inaccurate beliefs regarding vaccines or enhancing perceptions of vaccine efficacy is warranted.

Searching for the 'Trigger': An ethnographic analysis of parental beliefs regarding autism causation and vaccination in Puerto Rico

This study examines the personal beliefs held by parents of autistic children in Puerto Rico regarding the cause of their child's autism and how these beliefs may influence parental vaccination decision-making. This study seeks to contribute towards diversifying the autism literature by focusing on an autism community living in a relatively lower income, resource-deficit context. These findings expand our understandings of how parents of autistic children may perceive vaccines and how these perceptions are informed by various sources of knowledge. This ethnographic research study was conducted between May 2017 and August 2019. Methods included 350+ hours of participant-observation and semi-structured interviewing of 35 Puerto Rican parents of autistic children. 32 of these 35 parents interviewed believed autism to be the result of genetic risks that are 'triggered' by an unknown environmental factor. Suggested 'triggers' included various environmental contaminants and vaccinations. The subject of vaccination came up in every interview; 18 interviewed parents did not believe vaccines 'triggered' autism, 3 parents attributed their child's autism entirely to vaccines, while 14 considered vaccines to be one of several possible 'triggers'. It is important to note that no parents interviewed perceived vaccinations to be inherently or universally harmful. Rather, they perceived vaccinations to be one of many possible 'triggers' for a child predisposed to develop autism. In some cases, this perception prompted parents to oppose mandatory vaccination policies on the island. Parents shared nuanced, complex understandings of autism causation that may carry implications for COVID-19 vaccine uptake within the Puerto Rican autistic community.

What Determines Vaccine Hesitancy: Recommendations from Childhood Vaccine Hesitancy to Address COVID-19 Vaccine Hesitancy

Vaccine hesitancy is a prevalent and ongoing issue. However, due to the COVID-19 pandemic, additional attention has been brought to the topic of vaccine hesitancy. Vaccine hesitancy is a threat to the population's health globally. This article aims to acquire insights from previous literature to determine what works to increase vaccine uptake and how we can apply this knowledge to increase COVID-19 vaccine uptake. Research has focused chiefly on childhood vaccination and the hesitancy of caregivers. After conducting an extensive literature review, we have created a conceptual model of indicators that influence vaccine uptake for health providers and caregivers, which can also be used for vaccine recipients. Overall, the reasons for vaccine hesitancy are complex; therefore, a multifaceted approach is needed to address it. Understanding the factors that affect vaccine hesitancy will aid in addressing hesitancy and, in turn, lead to an increase in vaccine uptake.

COVID-19 vaccine hesitancy - reasons and solutions to achieve a successful global vaccination campaign to tackle the ongoing pandemic

The ongoing coronavirus disease (COVID-19) vaccination drive aims to achieve global vaccination coverage that will help to control the pandemic. Therefore, the individuals who are reluctant to be vaccinated or forego COVID-19 vaccination can delay the progress of overall vaccination coverage, leading to slower vaccination rates and may create obstacles in global efforts to control the circulation of SARS-CoV-2 as unvaccinated individuals can act as reservoirs of SARS-CoV-2 and could drive further outbreaks. Vaccine hesitancy is one of the major threats that directly impact global health as it challenges our ability to eradicate infectious diseases and achieve significant herd immunity through vaccination. One of the strategies to counter vaccine hesitancy is to follow a multisectoral approach that involves the collaboration between various stakeholders, such as government, private companies, religious groups, and other agencies, to leverage the knowledge, expertise, and resources, thereby enabling the creation of longstanding public trust of vaccines.

Encountering Parents Who Are Hesitant or Reluctant to Vaccinate Their Children: A Meta-Ethnography

(1) Background: Health professionals play an important role in addressing parents who are hesitant or reluctant to immunise their children. Despite the importance of this topic, gaps remain in the literature about these experiences. This meta-ethnography aimed to synthesise the available body of qualitative work about the care experiences of community and hospital health professionals in encounters with parents hesitant or reluctant to vaccinate their children. The aim is to provide key information for the creation of strategies that address vaccine hesitancy or refusal and ensure public trust in vaccination programs, which are required in a pandemic context such as the current one. (2) Methods: Noblit and Hare’s interpretive meta-ethnography of 12 studies was followed. A line of argument synthesis based on a metaphor was developed. (3) Results: The metaphor “The stone that refuses to be sculpted”, accompanied by three themes, symbolises the care experiences of health professionals in their encounters with parents that hesitate or refuse to vaccinate their children. (4) Conclusions: The creation of clearer communication strategies, the establishment of a therapeutic alliance, health literacy and the empowerment of parents are recommended. The incorporation of health professionals in decision making and the strengthening of multidisciplinary teams interacting with such parents are also included.

Perception of Health, Mistrust, Anxiety, and Indecision in a Group of Italians Vaccinated against COVID-19

The objectives of this study were to evaluate the psychological factors of health perception, mistrust, anxiety, fear, and indecision of Italians vaccinated against COVID-19, and conduct an analysis of the relationships between these factors and other variables: sex, vaccine priority ministerial categories, and the type and dose of vaccine. The participants included 1564 subjects who joined the vaccination campaign at the COVID-19 Vaccination Center in Salerno, Italy. A survey was conducted in the reference period March-April 2021 using a brief anamnestic questionnaire. In addition, the following standardized scales were used: the State-Trait Anxiety Inventory (STAI-Y) and the Short Form Health Survey (SF-12). The results showed that, in terms of the type of vaccine received, the interviewees felt more confident in having received the Comirnaty (Pfizer-BioNTech, 23.5%) and Vaxzevria (AstraZeneca, 18.6%) vaccines-feeling less tense (2.1%; Vaxzevria (AstraZeneca) = 3.2%), frightened (1%; Vaxzevria (AstraZeneca) = 1.4%), not at all nervous (61.1%; Vaxzevria (AstraZeneca), 43.6%), and not at all/undecided (67.9%; Vaxzevria (AstraZeneca), 58.6%). Regarding the mood and psychological states considered at the different vaccine administration times, other important differences emerged as the interviewees reported higher levels of tension, nervousness, and fear during the first phase of vaccine administration. Specifically, 40.7% (second dose, 32.7%) felt somewhat tense at the first dose, 26.4% felt frightened (second dose, 21.8%), and 33.8% felt nervous (second dose, 26.8%). The perceived state of health also increased at the end of the vaccination cycle, as, at the second dose, 15.4% of the sample reported an evaluation of "excellent" (first dose, 12.4%).
