Evidence-Based Strategies for Clinical Organizations to Address COVID-19 Vaccine Hesitancy

COVID-19 Vaccine Booster Hesitancy (VBH) of Healthcare Workers in Czechia: National Cross-Sectional Study

The emerging SARS-CoV-2 variants and waning vaccine-elicited immunity are two public health challenges that occurred simultaneously and synergistically during the summer of 2021 and led to a surging demand for COVID-19 vaccine booster dose (BD) rollout. This study aimed to evaluate the COVID-19 vaccine booster hesitancy (VBH) among Czech healthcare workers to explore the potential determinants of VBH. A national cross-sectional survey-based study was carried out between 3 and 11 November 2021, using an online self-administered questionnaire (SAQ) that explored the participants' demographic characteristics, COVID-19 infection and vaccine anamneses, willingness to receive COVID-19 vaccine BD, and the psychosocial drivers of VBH. A total of 3454 HCW properly responded to the online SAQ, of which 80.9% were females, 30.3% were medical professionals, and 50.5% were ≤47 years old. Most of the participants were already inoculated against SARS-CoV-2 (95.2%), and BTN162b2 was the most commonly administered vaccine (90.7%). As the study sample was planned to represent the target population, it revealed a high level of BD acceptance (71.3%) among Czech HCW, while 12.2% were still hesitant and 16.6% were against the currently available BD. These results are consistent with other recent results from central Europe. Medical professional, male, and older participants were more likely to accept BD rather than allied health professional, female, and younger participants. The BDs' perceived effectiveness against severe illness, symptomatic infection, and community transmission was a significant and strong predictor for BD acceptance, while the effectiveness against the circulating variants was not that important for our target population. The BDs' perceived safety and ethical dilemmas of vaccine justice should be addressed sufficiently while communicating with HCW and other population groups. The altruistic reasons for BD acceptance, i.e., family protection, patient protection, and community health protection, underpin the recommendation of postponing the COVID-19 vaccine mandating in favour of stressing these altruistic concerns amid public health messaging.

Public hesitancy to COVID‐19 vaccine and the role of pharmacists in addressing the problem and improving uptake

COVID‐19 is one of the worst pandemics in recent human history, causing huge health, economic, and psychosocial damage. Since the pandemic hit, several unsubstantiated claims regarding exposure, transmission and management have been disseminated. Misinformation and associated public confusion now extend to the COVID‐19 vaccines, spanning from claims based on possible links between some vaccine types and rare blood clots, to baseless claims. As a result, the public’s trust in COVID‐19 vaccines has been eroded, fuelling an already troubling trend of vaccine hesitancy. As medication experts and the most accessible healthcare providers, pharmacists are well equipped with the required skills and knowledge to improve COVID‐19 vaccine uptake by taking roles that range from dispelling myths, to providing reliable evidence‐based information, through to vaccine administration. This paper discusses public hesitancy to COVID‐19 vaccines, major contributing factors, and the role pharmacists can play in reducing hesitancy and increasing vaccine uptake.

Predictors of COVID-19 Vaccine Acceptance and Hesitancy among Healthcare Workers in Southern California: Not Just "Anti" vs. "Pro" Vaccine

In this study, we evaluated the status of and attitudes toward COVID-19 vaccination of healthcare workers in two major hospital systems (academic and private) in Southern California. Responses were collected via an anonymous and voluntary survey from a total of 2491 participants, including nurses, physicians, other allied health professionals, and administrators. Among the 2491 participants that had been offered the vaccine at the time of the study, 2103 (84%) were vaccinated. The bulk of the participants were middle-aged college-educated White (73%), non-Hispanic women (77%), and nursing was the most represented medical occupation (35%). Political affiliation, education level, and income were shown to be significant factors associated with vaccination status. Our data suggest that the current allocation of healthcare workers into dichotomous groups such as "anti-vaccine vs. pro-vaccine" may be inadequate in accurately tailoring vaccine uptake interventions. We found that healthcare workers that have yet to receive the COVID-19 vaccine likely belong to one of four categories: the misinformed, the undecided, the uninformed, or the unconcerned. This diversity in vaccine hesitancy among healthcare workers highlights the importance of targeted intervention to increase vaccine confidence. Regardless of governmental vaccine mandates, addressing the root causes contributing to vaccine hesitancy continues to be of utmost importance.

COVID-19 vaccine uptake and hesitancy among HIV-infected men who have sex with men in mainland China: a cross-sectional survey

BACKGROUND

Men who have sex with men (MSM), a population bearing the greatest HIV burden in many countries, may also be vulnerable to COVID-19. COVID-19 vaccines are essential to containing the pandemic. However, vaccine hesitancy may compromise vaccine coverage. We aimed to understand the uptake of COVID-19 vaccine and factors associated with COVID-19 vaccine hesitancy among HIV-infected MSM in mainland China.

METHODS

A cross-sectional online survey among HIV-infected MSM was conducted between 13 and 21 February 2021 in mainland China. Variables including demographics, mental health status, HIV characteristics, and knowledge of and attitudes toward COVID-19 pandemic and COVID-19 vaccine were collected. Chi-square tests and multivariable logistic regression were used to analyze factors associated with COVID-19 vaccine hesitancy.

RESULTS

A total of 1295 participants were included. The median age was 29.3 years (interquartile range [IQR] 25.2-34.0 years). The uptake of COVID-19 vaccine was 8.7%. Two main reasons for receiving vaccines were "regarded vaccination as self-health protection" (67.3%) and "trust in domestic medical technology" (67.3%). Among participants who did not initiate vaccination, concern about side effects (46.4%) and disclosure of HIV infection (38.6%) were top two reasons, and 47.2% had higher vaccine hesitancy. Men who had with high antiretroviral therapy (ART) adherence (adjusted odds ratio [aOR] 0.53, 95% confidence interval [CI] 0.35-0.80), often (0.26, 0.17-0.40) or sometimes (0.46, 0.31-0.67) paid attention to information about the COVID-19 vaccine, preferred domestic vaccines (0.37, 0.24-0.59), thought the pandemic had moderate (0.58, 0.38-0.90) and moderately severe or severe impact (0.54, 0.38-0.78) on immunity, who were waiting for vaccination programs organized at workplace (0.60, 0.44-0.81) and who were unaware of where to get COVID-19 vaccine (0.61, 0.45-0.82) had lower degree of COVID-19 vaccine hesitancy. Men who were concerned about the efficacy (1.72, 1.16-2.54) and side effects (2.44, 1.78-3.35) had higher degree of COVID-19 vaccine hesitancy.

CONCLUSION

COVID-19 vaccine uptake among HIV-infected MSM is still suboptimal. Understanding influencing factors of vaccine hesitancy among this group and making tailored measures to alleviate hesitancy would help improve the coverage of COVID-19 vaccination in this population.

Intention to get vaccinated against COVID-19 among nursing students: A cross-sectional survey

BACKGROUND

As the COVID-19 pandemic continues, safe and effective vaccines with high coverage remain the most effective way of controlling the infection. Therefore, the intention to get vaccinated is a critical issue for nursing students because they will act as health care providers and educators due to their future profession.

OBJECTIVES

This study aimed to explore factors associated with COVID-19 vaccination intention among Chinese nursing students.

DESIGN

A cross-sectional online survey was used.

PARTICIPANTS

A total of 1070 Chinese nursing students participated in this study.

METHODS

The study used structured self-administered questionnaires to assess the effects of the following elements; sociodemographic factors, vaccination status, beliefs on general vaccination, beliefs and attitudes towards COVID-19 and COVID-19 vaccination, and COVID-19 vaccination intention. Hierarchical regression analysis was conducted to examine the relationship between these variables and COVID-19 vaccination intention.

RESULTS

More than half (51.9%) of nursing students were willing to vaccinate against COVID-19, while 43.4% were uncertain and 4.7% were unwilling to get vaccinated. Increased likelihood of intention to get vaccinated was associated with positive beliefs towards general vaccination and COVID-19 vaccination, perceived less adverse effects following vaccination, the greater impact of COVID-19 on daily life, and less clinical practice experience in healthcare settings. Those hesitant to vaccinate raised concerns about the safety of vaccines, doubted the efficacy, believed that vaccination was unnecessary, or had insufficient information on COVID-19 vaccines.

CONCLUSIONS

More efforts are needed to enhance vaccine confidence and increase the vaccination rates against COVID-19 in nursing students by organizing effective educational campaigns and establishing positive vaccination beliefs.

The impact of perceived crisis severity on intention to use voluntary proximity tracing applications

During a crisis such as COVID-19, governments ask citizens to adopt various precautionary behaviours, such as using a voluntary proximity tracing application (PTA) for smartphones. However, the willingness of individual citizens to use such an app is crucial. Crisis decision theory can be used to better understand how individuals assess the severity of the crisis and how they decide whether or not to adopt the precautionary behaviour. We propose a research model to examine the direct influence of perceived crisis severity on intention to use the technology, as well as the indirect impact via PTAs' benefits for citizens. Exploratory and confirmatory factor analyses confirm the two dimensions of the benefits, namely personal and societal benefits. We used PLS-MGA to evaluate our research model. The results confirm the influence of the perceived severity of COVID-19 on the intention to use the PTA, as well as the mediating effects of personal and societal benefits on this relationship. Our findings contribute to the technology adoption literature and showcase the use of crisis decision theory in the field of information systems.

College students' sleep difficulty during COVID-19 and correlated stressors: A large-scale cross-sessional survey study

Objective

Sleep difficulty is one of the main concerns during the COVID-19 pandemic. This study examined factors related to vaccination and physical and psychological health conditions, and sleep difficulty in college students in China.

Methods

An online, cross-sectional, anonymous survey was used to investigate college students' perceived sleep difficulty and relevant components (i.e., physical health condition, psychological distress, knowledge of vaccine, and autonomy of vaccine uptake). Hierarchical ordinal logistic regression was conducted to examine the proposed model with the control of participants' demographics (i.e., gender and age).

Results

Valid data of 3,145 students from 43 universities in mainland China was collected in January 2021. The average age of participants was 20.8 years old (S. D. = 2.09). The majority were single (97.4%), and about half were male (49.8%). Results showed that participants had less psychological distress when they had more knowledge about the COVID-19 vaccine and more autonomy to decide whether to receive it. In addition, participants with better physical health experienced less sleep difficulty. In contrast, those with more psychological distress experienced more sleep difficulty.

Conclusions

These findings can inform healthcare providers about the relationship between different factors and difficulty sleeping and aid them in developing interventions addressing sleep difficulties associated with the global pandemic. Health authorities also can improve vaccine uptake and reduce hesitancies in future vaccination campaigns based on the study results showing that greater vaccine knowledge and autonomy reduced psychological distress.

HPV immunization among young adults (HIYA!) in family practice: A quality improvement project

AIMS

Thousands of anogenital and oropharyngeal cancers every year might be prevented through increased receipt of vaccination against the human papillomavirus (HPV). This project aimed to (1) increase the rate of HPV vaccination status assessment, and (2) improve HPV vaccine initiation and completion rates among 18 to 26-year-old patients in the family practice setting.

DESIGN

Quality improvement project, pre/post intervention design.

METHODS

This project implemented the HIYA! (HPV Immunization among Young Adults) Intervention in a private sports and family practice in central New Jersey. HIYA! implemented 10 pre-, during, and post-visit outcome measures during every family medicine visit with an 18 to 26-year-old patient for HPV. Data collection involved retrospective chart review of every eligible patient during the 12-week implementation period from 17 August to 06 November 2020 and during the same 12-week control period in 2019.

RESULTS/FINDINGS

One hundred sixteen charts from 2019 and 129 charts from 2020 were reviewed for assessment of HPV vaccination status and HPV vaccine initiation and/or completion. Multivariable logistic regression analysis demonstrated that participants in the control group were 84% less likely to be assessed for HPV vaccination status and were 91% less likely to initiate and complete HPV vaccination compared with the intervention group.

CONCLUSION

This QI project found HIYA! to be an effective and feasible strategy to improve HPV vaccination rates among 18 to 26-year-old patients in a family practice setting.

IMPACT

The human papillomavirus (HPV) is the most common sexually transmitted disease in the United States, and causes thousands of cancers annually. Although vaccination against HPV can prevent these cancers, vaccination rates remain low, particularly among young adults ages 18 to 26 years. The positive impact of HIYA! was evident based on its success despite the unique challenges presented during the implementation period due to the COVID-19 pandemic.

The Mediating Roles of Medical Mistrust, Knowledge, Confidence and Complacency of Vaccines in the Pathways from Conspiracy Beliefs to Vaccine Hesitancy

Background: Vaccine hesitancy, associated with medical mistrust, confidence, complacency and knowledge of vaccines, presents an obstacle to the campaign against the coronavirus disease 2019 (COVID-19). The relationship between vaccine hesitancy and conspiracy beliefs may be a key determinant of the success of vaccination campaigns. This study provides a conceptual framework to explain the impact of pathways from conspiracy beliefs to COVID-19 vaccine hesitancy with regard to medical mistrust, confidence, complacency and knowledge of vaccines. Methods: A non-probability study was conducted with 1015 respondents between 17 April and 28 May 2021. Conspiracy beliefs were measured using the coronavirus conspiracy scale of Coronavirus Explanations, Attitudes, and Narratives Survey (OCEANS), and vaccine conspiracy beliefs scale. Medical mistrust was measured using the Oxford trust in doctors and developers questionnaire, and attitudes to doctors and medicine scale. Vaccine confidence and complacency were measured using the Oxford COVID-19 vaccine confidence and complacency scale. Knowledge of vaccines was measured using the vaccination knowledge scale. Vaccine hesitancy was measured using the Oxford COVID-19 vaccine hesitancy scale. Confirmatory factor analysis (CFA) was used to evaluate the measurement models for conspiracy beliefs, medical mistrust, confidence, complacency, and knowledge of vaccines and vaccine hesitancy. The structural equation modeling (SEM) approach was used to analyze the direct and indirect pathways from conspiracy beliefs to vaccine hesitancy. Results: Of the 894 (88.1%) respondents who were willing to take the COVID-19 vaccine without any hesitancy, the model fit with the CFA models for conspiracy beliefs, medical mistrust, confidence, complacency and knowledge of vaccines, and vaccine hesitancy was deemed acceptable. Conspiracy beliefs had significant direct (β = 0.294), indirect (β = 0.423) and total (β = 0.717) effects on vaccine hesitancy; 41.0% of the total effect was direct, and 59.0% was indirect. Conspiracy beliefs significantly predicted vaccine hesitancy by medical mistrust (β = 0.210), confidence and complacency (β = 0.095), knowledge (β = 0.079) of vaccines, explaining 29.3, 11.0, and 13.2% of the total effects, respectively. Conspiracy beliefs significantly predicted vaccine hesitancy through the sequential mediation of knowledge of vaccines and medical mistrust (β = 0.016), explaining 2.2% of the total effects. Conspiracy beliefs significantly predicted vaccine hesitancy through the sequential mediation of confidence and complacency, and knowledge of vaccines (β = 0.023), explaining 3.2% of the total effects. The SEM approach indicated an acceptable model fit (χ²/df = 2.464, RMSEA = 0.038, SRMR = 0.050, CFI = 0.930, IFI = 0.930). Conclusions: The sample in this study showed lower vaccine hesitancy, and this study identified pathways from conspiracy beliefs to COVID-19 vaccine hesitancy in China. Conspiracy beliefs had direct and indirect effects on vaccine hesitancy, and the indirect association was determined through medical mistrust, confidence, complacency, and knowledge of vaccines. In addition, both direct and indirect pathways from conspiracy beliefs to vaccine hesitancy were identified as intervention targets to reduce COVID–19 vaccine hesitancy.

Willingness to Accept Expedited COVID-19 Vaccine Research for Children Aged <12 Years After Adult Vaccine Approval

PURPOSE

The goal of this study was to assess if caregivers' attitudes toward the regulatory process of approving the vaccine against coronavirus disease 2019 (COVID-19) for children aged <12 years changed after a vaccine was approved for adults.

METHODS

This was a larger scale COVIPAS (COVID-19 Parental Attitude Study) survey of caregivers presenting with their children aged ≤12 years for emergency care in 12 hospitals in the United States, Canada, and Israel. The study compared willingness to support abridged research into COVID-19 vaccines for children between the peak of the pandemic (March-May 2020) and after a COVID-19 vaccine became available for adults (December 2020-March 2021).

FINDINGS

A total of 1956 surveys were included in the analyses. Overall, 385 (30.9%) caregivers in the pre-vaccine approval period and 250 (35.3%) caregivers in the post-adult vaccine phase supported abridged research into COVID-19 vaccines (P < 0.001). In both phases, mothers were less likely to favor abridged approval. Those with children who were fully vaccinated based on the pediatric schedule in their country favored abridged approval in phase 1 (odds ratio, 1.98; 95% confidence interval, 1.31-3.08) but less so in phase 2. In both phases, age and concerns of parents that they had COVID-19 or their child had COVID-19 were not associated with changes in response between phases.

IMPLICATIONS

Willingness to expedite vaccine approval increased after the emergency approval of COVID-19 vaccine for adults. Mothers are much less likely to approve expedited approval. No significant changes have been found in the composition of caregivers willing to forego regulatory demands on vaccine approval.

Reducing COVID-19 Vaccine Hesitancy by Implementing Organizational Intervention in a Primary Care Setting in Bahrain

Background: Refusal to receive the COVID-19 vaccine or hesitancy is a global threat. Hence, reducing vaccine hesitancy is the next challenge for policymakers and the healthcare system. However, people trust healthcare professionals more than any other source of information. Accordingly, planning for an effective process and competent healthcare professional to elicit and address the patient's concerns is an imperative measure. This quality improvement project aimed to improve physicians’ COVID-19 vaccine advice to reduce vaccine hesitancy.

Methods: The study used judgmental sampling and involved 665 hesitant patients over 19 weeks. The team utilized the Plan-Do-Study-Act method to implement COVID-19 vaccine physicians’ reminders and upgrades physicians’ communication skills to conduct an effective tailored communication that addresses the patient’s concerns toward COVID-19 vaccines. The team used pre-post design to evaluate the impact of counseling on the hesitancy rate of patients before and after the intervention over time. The main outcomes were the percentage of physicians’ COVID-19 vaccine advice for patients and the percentage of hesitancy rate before and after implementation.

Results: There were 665 hesitant patients before intervention. However, after the intervention, the number decreased to 193 patients, and the control chart revealed a reliable process. The percentage of recommendations by physicians has increased from 1% to 51% after 19 weeks of implementation and with a controlled process.

Conclusion: The study has found that rectifying process barriers and upgrading physicians’ skills would improve the COVID-19 vaccine counseling rate and introducing tailored communication would reduce the hesitancy rate. Nevertheless, the study was constrained by a lack of information on the impact of social media and national measures on patients’ decisions. Additional studies with more emphasis on other patients’ behavior determinants are necessary.

Attitudes of patients with severe mental illness towards COVID-19 vaccinations: A preliminary report from a public psychiatric hospital

BACKGROUND

As patients with severe mental illness are at increased risk for COVID-19 mortality, the issue of willingness to be vaccinated is of extreme importance.

METHODS

During February 2021 Shalvata Mental Health hospital provided Covid-19 vaccines to its patients. Fifty one patients suffering from severe mental illness, out of 196 patients hospitalized in closed, open or day wards during that period, signed the informed consent and were assessed for their clinical condition (OQ-45), fear of Covid-19 (FCV-19S) and approach to the vaccine (C19-VHS). All patients who were not vaccinated in February 2021 (baseline) were re-approached a month later to assess whether they had gotten vaccinated since.

RESULTS

Patients who were not vaccinated at baseline had an oppositional approach to the vaccine, and did not significantly differ in their fear of Covid-19 levels or in levels of clinical severity (t(49) = 2.51, p = 0.02) from those who were vaccinated. From the 29 patients who were not vaccinated at baseline approach to the vaccine was a good predictor to getting vaccinated after one month (79% positive predictive value).

CONCLUSIONS

The majority of patients suffering from a severe mental illness are willing to get vaccinated, and their decision of whether or not to get vaccinated is based on their viewpoint on the vaccine rather than being an outcome of their level of distress (OQ-45). It is important to allow vaccine accessibility to hospitalized patients, to consider their opinions and to provide useful information to lower vaccine hesitancy and improve vaccination rates.

COVID-19 Vaccination and Non-COVID-19 Mortality Risk - Seven Integrated Health Care Organizations, United States, December 14, 2020-July 31, 2021

By September 21, 2021, an estimated 182 million persons in the United States were fully vaccinated against COVID-19.* Clinical trials indicate that Pfizer-BioNTech (BNT162b2), Moderna (mRNA-1273), and Janssen (Johnson & Johnson; Ad.26.COV2.S) vaccines are effective and generally well tolerated (1-3). However, daily vaccination rates have declined approximately 78% since April 13, 2021^†; vaccine safety concerns have contributed to vaccine hesitancy (4). A cohort study of 19,625 nursing home residents found that those who received an mRNA vaccine (Pfizer-BioNTech or Moderna) had lower all-cause mortality than did unvaccinated residents (5), but no studies comparing mortality rates within the general population of vaccinated and unvaccinated persons have been conducted. To assess mortality not associated with COVID-19 (non-COVID-19 mortality) after COVID-19 vaccination in a general population setting, a cohort study was conducted during December 2020-July 2021 among approximately 11 million persons enrolled in seven Vaccine Safety Datalink (VSD) sites.^§ After standardizing mortality rates by age and sex, this study found that COVID-19 vaccine recipients had lower non-COVID-19 mortality than did unvaccinated persons. After adjusting for demographic characteristics and VSD site, this study found that adjusted relative risk (aRR) of non-COVID-19 mortality for the Pfizer-BioNTech vaccine was 0.41 (95% confidence interval [CI] = 0.38-0.44) after dose 1 and 0.34 (95% CI = 0.33-0.36) after dose 2. The aRRs of non-COVID-19 mortality for the Moderna vaccine were 0.34 (95% CI = 0.32-0.37) after dose 1 and 0.31 (95% CI = 0.30-0.33) after dose 2. The aRR after receipt of the Janssen vaccine was 0.54 (95% CI = 0.49-0.59). There is no increased risk for mortality among COVID-19 vaccine recipients. This finding reinforces the safety profile of currently approved COVID-19 vaccines in the United States.

Correlates of COVID-19 Vaccine Acceptance, Hesitancy and Refusal among Employees of a Safety Net California County Health System with an Early and Aggressive Vaccination Program: Results from a Cross-Sectional Survey

Since health professionals provide frontline care to COVID-19 patients, information on vaccine acceptance among healthcare workers is needed. We developed and implemented an anonymous internet-based cross-sectional survey with direct solicitation among employees of a safety net health system. Items queried demographic and health-related characteristics, experience with and knowledge of COVID-19, and determinants of decisions to vaccinate. COVID-19 vaccine acceptance groups (acceptors, hesitant, refusers) were defined; an adapted version of the WHO vaccine hesitancy scale was included. The survey demonstrated good reliability (Cronbach’s alpha = 0.92 for vaccine hesitancy scale; 0.93 for determinants). General linear and logistic regression methods examined factors which were univariately associated with vaccine hesitancy and vaccine acceptance, respectively. Multivariable models were constructed with stepwise model-building procedures. Race/ethnicity, marital status, job classification, immunocompromised status, flu vaccination and childhood vaccination opinions independently predicted hesitancy scale scores. Gender, education, job classification and BMI independently predicted acceptance, hesitancy, and refusal groups. Among hesitant employees, uncertainty was reflected in reports of motivating factors influencing their indecision. Despite a strong employee-support environment and job protection, respondents reported physical and mental health effects. The appreciation of varied reasons for refusing vaccination should lead to culturally sensitive interventions to increase vaccination rates amongst healthcare workers.

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.

The future of COVID-19: A vaccine review

The COVID-19 pandemic has impacted individuals, families, and communities for well over a year, and has brought light to how a broad range of social, economic, and historically relevant factors take massive tolls on the health and well-being of underserved communities around the world. This literature review aims to bring light to the current landscape of vaccines, disparities that exist in COVID-19 response, the historical relevance of the ongoing pandemic, and what needs to be accomplished for a more prepared response to potential future pandemics. It will be shown that as the world continues become more interconnected, amplification of international cooperation and well-funded response organizations are imperative to provide more equitable care in future health crises. The synthesis of current research will be helpful to researchers analyzing historical trends in the COVID-19 pandemic and individuals interested in better understanding and advocating for underserved communities across the globe.

Exploring COVID-19 vaccine hesitancy at a rural historically black college and university

OBJECTIVES

Minorities have been disproportionately affected by the coronavirus disease 2019 (COVID-19) yet have the lowest COVID-19 vaccine rate. Vaccine hesitancy has been reported at higher rates in African Americans (AAs) and young adults. This study aimed to assess COVID-19 vaccine hesitancy, determine the rationale for receiving or declining the COVID-19 vaccine, and propose strategies to address confidence in faculty, staff, and students at a rural historically black college and university (HBCU).

METHODS

A study was conducted using an electronic survey administered to a convenient sample of 210 faculty, students, and staff at the University of Maryland Eastern Shore, an HBCU in a rural community.

RESULTS

Most participants were 18 to 24 years old (69%), college students (73.89%), AA (70%), and identified as a woman (70%). Notably, 87% of participants were nonhesitant (received one dose or intended to be vaccinated). Approximately 54% had already received at least one dose of a COVID-19 vaccine. Only 13% of participants were hesitant and did not plan to receive the COVID-19 vaccine. The most common rationale for vaccine hesitancy was mistrust of the health care system or government toward AAs.

CONCLUSION

The results show that vaccine hesitancy was low in the predominantly young-adult AA population at a rural HBCU. However, opportunities exist for pharmacists and other accessible health care professionals to contribute to efforts aimed at decreasing vaccine hesitancy and improving vaccine confidence.

"First Do No Harm". No-Fault Compensation Program for COVID-19 Vaccines as Feasibility and Wisdom of a Policy Instrument to Mitigate Vaccine Hesitancy

Vaccines are so far proven to be safe, although related adverse events cannot be excluded. The urgency for COVID-19 vaccines determined a dilution of the general expectations of safety and efficacy of vaccination (from safe and effective to safe and effective enough). In many countries, a no-fault program was established to compensate individuals who experienced serious vaccine-related injuries. The impressive number of administrations worldwide and the legal indemnity afforded to manufacturers of approved vaccines that cannot be pursued for compensation fed the debate about the availability of a compensation model for COVID-19 vaccine-related injuries. Several European countries have long introduced a system, Vaccine Injury Compensation Programs, to compensate people who suffer physical harm because of vaccination. In Europe, COVID-19 vaccination is strongly recommended for the general population and in many states is declared mandatory for healthcare workers. In 1992, Italy edited Law no. 210 providing legal protection for individuals who reported injuries after mandatory and recommended vaccinations as a no-fault alternative to the traditional tort system. Despite its recommended nature, COVID-19 vaccination is excluded from the no-fault model in several European states, and the Italian government is called to provide clear and firm instructions for the management of the many requests for compensation. The authors provide an overview of the existing compensation models in Europe and analyse available legislative proposals.

Population preferences and attitudes towards COVID-19 vaccination: a cross-sectional study from Pakistan

BACKGROUND

While vaccine development is itself a challenge; ensuring optimal vaccine uptake at population level can present an even more significant challenge. Therefore, this study aimed to assess the Pakistani population's attitude and preferences towards the Coronavirus disease 2019 (COVID-19) vaccine.

METHOD

A cross-sectional study was carried out through an online self-administered questionnaire from 27 September 2020 to 11 October 2020. A total of 883 people responded to the survey. The questionnaire included the participants' socio-demographic variables, attitudes, beliefs towards the COVID-19 vaccine and acceptance and rejection of vaccination, and reasons for them. Logistic regression analysis was used to analyze the predictors for vaccine acceptance and willingness to pay for the vaccine.

RESULTS

A majority (70.8%) of respondents will accept the COVID-19vaccine if available, and 66.8% showed a positive attitude towards vaccination. Monthly family income, education level, self-diagnosis of COVID-19 or a friend, family member, or colleague are significant factors influencing the acceptance of COVID-19 vaccination. The dogma of being naturally immune to COVID-19 was a key reason for the refusal of the vaccine. Less than half (48%) of those who refuse will vaccinate themselves if government officials have made it compulsory. A third (33.9%) of participants were willing to pay up to (7 USD) 1000 Pkr (Pakistani Rupees) for the vaccine.

CONCLUSION

The population's positive attitude should be improved by increasing awareness and eradicating false myths about vaccines through large-scale campaigns.

Intent to Vaccinate SARS-CoV-2 Infected Children in US Households: A Survey

A paucity of data exists evaluating a guardian's intent to vaccinate their child against COVID-19 in the United States. We administered 102 first (April-November 2020) and 45 second (December-January 2020-2021) surveys to guardians of children (<18 years) who had a laboratory-confirmed diagnosis of COVID-19 and assessed their intent to give a COVID-19 vaccine to their child, when one becomes available. The first and second surveys of the same cohort of guardians were conducted before and following the press releases detailing the adult Pfizer-BioNTech and Moderna Phase 3 results. Both surveys included an intent-to-vaccinate question using the subjective language of "if a safe and effective vaccine" became available, and a second question was added to second surveys using the objective language of "would prevent 19 of 20 people from getting disease". When using subjective language, 24 of 45 (53%) guardians endorsed vaccine administration for their children in the first survey, which decreased to 21 (46%) in the second survey. When adding objective language, acceptance of vaccination increased to 31 (69%, p = 0.03). Common reasons for declining vaccination were concerns about adverse effects and/or vaccine safety. Providing additional facts on vaccine efficacy increased vaccine acceptance. Evidence-based strategies are needed to increase pediatric COVID-19 vaccine uptake.

Oxford COVID-19 Vaccine Hesitancy in School Principals: Impacts of Gender, Well-Being, and Coronavirus-Related Health Literacy

Purposes: To explore the associated factors of COVID-19 vaccine hesitancy and examine psychometric properties of the coronavirus-related health literacy questionnaire (HLS-COVID-Q22) and Oxford COVID-19 Vaccine Hesitancy questionnaire. Methods: An online survey was conducted from 23 June to 16 July 2021 on 387 school principals across Taiwan. Data collection included socio-demographic characteristics, information related to work, physical and mental health, COVID-19 related perceptions, sense of coherence, coronavirus-related health literacy, and vaccine hesitancy. Principal component analysis, correlation analysis, linear regression models were used for validating HLS-COVID-Q22, Oxford COVID-19 Vaccine Hesitancy, and examining the associations. Results: HLS-COVID-Q22 and Oxford COVID-19 Vaccine Hesitancy were found with satisfactory construct validity (items loaded on one component with factor loading values range 0.57 to 0.81, and 0.51 to 0.78), satisfactory convergent validity (item-scale correlations range 0.60 to 0.79, and 0.65 to 0.74), high internal consistency (Cronbach’s alpha = 0.96 and 0.90), and without floor or ceiling effects (percentages of possibly lowest score and highest score <15%), respectively. Low scores of vaccine hesitancy were found in male principals (regression coefficient, B, −0.69; 95% confidence interval, 95%CI, −1.29, −0.10; p = 0.023), principals with better well-being (B, −0.25; 95%CI, −0.47, −0.03; p = 0.029), and higher HLS-COVID-Q22 (B, −1.22; 95%CI, −1.89, −0.54; p < 0.001). Conclusions: HLS-COVID-Q22 and Oxford COVID-19 Vaccine Hesitancy were valid and reliable tools. Male principals and those with better well-being, and higher health literacy had a lower level of vaccine hesitancy. Improving principals’ health literacy and well-being is suggested to be a strategic approach to increase vaccine acceptance for themselves, their staff, and students.

Young Adult Perspectives on COVID-19 Vaccinations

PURPOSE

Young adults have the highest cumulative incidence of COVID-19 infection in the country. Using March 2021 Household Pulse Survey data, an ongoing, cross-sectional nationally representative survey, we examined U.S. young adult intention to accept COVID-19 vaccines.

METHODS

Young adult (ages 18-25 years) Household Pulse Survey participants were queried on intention to receive a COVID-19 vaccine and related perspectives (N = 5,082).

RESULTS

Most unvaccinated respondents (76%) indicated an intention to become vaccinated. The most frequently cited reasons for potentially rejecting vaccination included desire to wait and see if the vaccine is safe (56%); concerns over side effects (53%); and believing others are in greater need of the vaccine (44%).

CONCLUSIONS

With 24% of young adults hesitant to accept a COVID-19 vaccine, public health interventions should target reasons for hesitancy, address concerns about safety and side effects, and underscore the importance of vaccinations for this population.

Public Perceptions of COVID-19 Vaccines: Policy Implications from US Spatiotemporal Sentiment Analytics

There is a compelling and pressing need to better understand the temporal dynamics of public sentiment towards COVID-19 vaccines in the US on a national and state-wise level for facilitating appropriate public policy applications. Our analysis of social media data from early February and late March 2021 shows that, despite the overall strength of positive sentiment and despite the increasing numbers of Americans being fully vaccinated, negative sentiment towards COVID-19 vaccines still persists among segments of people who are hesitant towards the vaccine. In this study, we perform sentiment analytics on vaccine tweets, monitor changes in public sentiment over time, contrast vaccination sentiment scores with actual vaccination data from the US CDC and the Household Pulse Survey (HPS), explore the influence of maturity of Twitter user-accounts and generate geographic mapping of tweet sentiments. We observe that fear sentiment remained unchanged in populous states, whereas trust sentiment declined slightly in these same states. Changes in sentiments were more notable among less populous states in the central sections of the US. Furthermore, we leverage the emotion polarity based Public Sentiment Scenarios (PSS) framework, which was developed for COVID-19 sentiment analytics, to systematically posit implications for public policy processes with the aim of improving the positioning, messaging, and administration of vaccines. These insights are expected to contribute to policies that can expedite the vaccination program and move the nation closer to the cherished herd immunity goal.

Motivation to COVID-19 Vaccination and Reasons for Hesitancy in Employees of a Czech Tertiary Care Hospital: A Cross-Sectional Survey

High vaccination coverage among healthcare workers (HCWs) is crucial for managing the COVID-19 pandemic. The aim was to determine the demand for vaccination among all employees (n = 4553) of a tertiary care hospital after several weeks of the vaccine's availability, and to analyze motives for acceptance and reasons for hesitancy through an anonymous online questionnaire. Upon the completion of data collection, the hospital's vaccination coverage was at 69.8%. A total of 3550 completed questionnaires were obtained (2657 from vaccinated, 893 from unvaccinated employees). Significant predictors of vaccine acceptance were: age (odds ratio (OR) 1.01, 95% confidence interval (CI) 1.01-1.02), sex (OR (females) 0.58, 95% CI 0.45-0.75), job type (OR (non-physician HCWs) 0.54, 95% CI 0.41-0.72; OR (non-HCWs) 0.51, 95% CI 0.37-0.71), fear of COVID-19 (OR 1.4, 95% CI 1.34-1.46), history of COVID-19 (OR 0.41, 95% CI 0.34-0.49) and of influenza vaccination (OR 2.74, 95% CI 2.12-3.57). The most frequent motive for acceptance was the effort to protect family members (84%), while concerns about vaccine safety and side effects (49.4%), followed by distrust in the vaccine's efficacy (41.1%) were the top reasons for hesitancy. To increase vaccination coverage among HCWs, it is necessary to raise awareness of vaccine safety and efficacy.

Using Influenza Vaccination Location Data from the 2018 Behavioral Risk Factor Surveillance System (BRFSS) to Expand COVID-19 Vaccination Coverage

Effective COVID-19 vaccine distribution requires prioritizing locations that are accessible to high-risk target populations. However, little is known about the vaccination location preferences of individuals with underlying chronic conditions. Using data from the 2018 Behavioral Risk Factor Surveillance System (BRFSS), we grouped 162,744 respondents into high-risk and low-risk groups for COVID-19 and analyzed the odds of previous influenza vaccination at doctor’s offices, health departments, community settings, stores, or hospitals. Individuals at high risk for severe COVID-19 were more likely to be vaccinated in doctor’s offices and stores and less likely to be vaccinated in community settings.

Promoting coronavirus disease 2019 (COVID-19) vaccination among healthcare personnel: A multifaceted intervention at a tertiary-care center in Japan

Objective:

The coronavirus disease 2019 (COVID-19) vaccine may hold the key to ending the pandemic, but vaccine hesitancy is hindering the vaccination of healthcare personnel (HCP). We examined their perceptions of the COVID-19 vaccine and implemented an intervention to increase vaccination uptake.

Design:

Before-and-after trial.

Participants and setting:

Healthcare personnel at a 790-bed tertiary-care center in Tokyo, Japan.

Interventions:

A prevaccination questionnaire was administered to HCP to examine their perceptions of the COVID-19 vaccine. A multifaceted intervention was then implemented involving (1) distribution of informational leaflets to all HCP, (2) hospital-wide announcements encouraging vaccination, (3) a mandatory lecture, (4) an educational session about the vaccine for pregnant or breastfeeding HCP, and (5) allergy testing for HCP at risk of allergic reactions to the vaccine. A postvaccination survey was also performed.

Results:

Of 1,575 HCP eligible for enrollment, 1,224 (77.7%) responded to the questionnaire, 533 (43.5%) expressed willingness to be vaccinated, 593 (48.4%) were uncertain, and 98 (8.0%) expressed unwillingness to be vaccinated. The latter 2 groups were concerned about the vaccine’s safety rather than its efficacy. After the intervention, the overall vaccination rate reached 89.7% (1,413 of 1,575), and 88.9% (614 of 691) of the prevaccination survey respondents answered “unwilling” to or “unsure” about eventually receiving a vaccination. In the postvaccination questionnaire, factors contributing to increased COVID-19 vaccination included information and endorsement of vaccination at the medical center (274 of 1,037, 26.4%).

Conclusions:

This multifaceted intervention increased COVID-19 vaccinations among HCP at a Japanese hospital. Frequent support and provision of information were crucial for increasing the vaccination rate and may be applicable to the general population as well.

Evidence-based strategies to promote vaccine acceptance

The success of a vaccination programme depends upon its coverage so that it provides herd immunity. Vaccine hesitancy has the potential to undermine a vaccine programme. Evidence suggests that some strategies are more effective in promoting vaccination uptake. Community nurses should help in the promotion of vaccination uptake using evidence-based interventions and through 'Making Every Contact Count'.

Role of Information Technology in COVID-19 Vaccination Drive: An Analysis of the COVID-19 Global Beliefs, Behaviors, and Norms Survey

With the onset of the COVID-19 pandemic, information technology has played a critical role in healthcare. A broad spectrum of information technology tools and applications played an essential role to create awareness of the COVID-19 vaccination drive and its health benefits. Research conducted by Massachusetts Institute of Technology (MIT) in collaboration with information technology platforms like Facebook with inputs from World Health Organization (WHO), John Hopkins University (JHU), and Global Outbreak Alert and Response Network (GOARN) shows that 65.06% of people all over the globe are willing to get vaccinated. Vaccine acceptance depends upon social norms and human behavior. These organizations conducted the global survey in over 60 countries with a sample size of 437,236 responses. The international survey was organized using a pre-registered randomized experiment demonstrating the role of technology in reaching out to people based in diverse communities and evaluating their beliefs, behavior, and social norms. The study shows that vaccine acceptance can vary due to descriptive norms. All the respondents in the study were adults with access to the internet. Moreover, a large proportion of the population thinks that the COVID-19 pandemic is a viable threat to the community and preventive measures need to be taken including vaccination drives to eradicate the menace. The survey consisted of five blocks involving questions related to healthcare, demographics, vaccines, knowledge, and information exposure. Sampling and weighting were done using a pool of 3,000 respondents over two weeks, and weights were provided per respondent to represent the target population as a whole. It reduces the representation error and minimizes non-response biases.

Ensuring High and Equitable COVID-19 Vaccine Uptake Among Patients With IBD

The recent emergency use authorization of a third COVID-19 vaccine means that most patients with inflammatory bowel disease (IBD) will soon be eligible to be vaccinated. Gastroenterology clinicians should be prepared to address patients' concerns regarding safety and efficacy of vaccines. They should also strongly recommend that all their patients be vaccinated with a COVID-19 vaccine. Additionally, they should be prepared to educate patients about logistics that will result in successful vaccination completion. All these measures will be crucial to ensure high uptake among their patients with IBD.

Hospitalist perspectives on barriers to recommend and potential benefit of the COVID-19 vaccine

Background: Hospitalists, comprised of nurse practitioners and physician assistants (collectively, advanced practice providers [APPs]) and physicians, have opportunities to counsel patients and reduce SARS-CoV-2 related coronavirus disease 2019 (COVID-19) vaccine hesitancy. However, hospitalist perspectives on the COVID-19 vaccine and potential differences between APPs and physicians are unknown. Understanding hospitalist perspectives could help to address vaccine hesitancy among patients.Methods: We conducted an online survey of hospitalists at Mayo Clinic sites in Arizona, Florida, Minnesota, and Wisconsin from 14 December 2020 through 4 January 2021. We collected demographic information and assessed perspectives on the COVID-19 vaccine and, for comparison, on the influenza vaccine. Descriptive statistics were used to compare responses between APPs and physicians.Results: The overall response rate was 42.7% (n = 128/300) and comprised of 53.9% women (n = 69/128) and 41.4% APPs (n = 53/128). Most hospitalists reported receiving or planning to receive vaccination against COVID-19 (93.7%; n = 119/128) and influenza (97.7%; n = 125/128). Most hospitalists reported they would advise 100% of patients to receive the COVID-19 vaccine (66% for APPs; 74.7% for physicians) and influenza vaccine (83% for APPs; 80% for physicians). Barriers to recommending the COVID-19 vaccine included patient health status and vaccine safety profile. Hospitalists reported that patients and coworkers receiving the COVID-19 vaccine would reduce their anxiety (~80% of hospitalists), social isolation (~64% of hospitalists), and improve their emotional support (~40% of hospitalists). APP and physician responses were similar. The possible reduction in social isolation was associated with higher odds of hospitalists advising all patients to receive the COVID-19 vaccine (adjusted odds ratio 2.95 [95% confidence interval, 1.32-6.59]; P< .008), whereas hospitalist age, gender, and profession showed no association.Conclusion: Most hospitalists would reportedly advise patients to receive the COVID-19 vaccine. Barriers to this recommendation included patient health status and vaccine safety. Hospitalists are an important resource to provide patient education and reduce COVID-19 vaccine hesitancy.

Health Care Providers' Trusted Sources for Information About COVID-19 Vaccines: Mixed Methods Study

BACKGROUND

Information and opinions shared by health care providers can affect patient vaccination decisions, but little is known about who health care providers themselves trust for information in the context of new COVID-19 vaccines.

OBJECTIVE

The purpose of this study is to investigate which sources of information about COVID-19 vaccines are trusted by health care providers and how they communicate this information to patients.

METHODS

This mixed methods study involved a one-time, web-based survey of health care providers and qualitative interviews with a subset of survey respondents. Health care providers (physicians, advanced practice providers, pharmacists, nurses) were recruited from an integrated health system in Southern California using voluntary response sampling, with follow-up interviews with providers who either accepted or declined a COVID-19 vaccine. The outcome was the type of information sources that respondents reported trusting for information about COVID-19 vaccines. Bivariate tests were used to compare trusted information sources by provider type; thematic analysis was used to explore perspectives about vaccine information and communicating with patients about vaccines.

RESULTS

The survey was completed by 2948 providers, of whom 91% (n=2683) responded that they had received ≥1 dose of a COVID-19 vaccine. The most frequently trusted source of COVID-19 vaccine information was government agencies (n=2513, 84.2%); the least frequently trusted source was social media (n=691, 9.5%). More physicians trusted government agencies (n=1226, 93%) than nurses (n=927, 78%) or pharmacists (n=203, 78%; P<.001), and more physicians trusted their employer (n=1115, 84%) than advanced practice providers (n=95, 67%) and nurses (n=759, 64%; P=.002). Qualitative themes (n=32 participants) about trusted sources of COVID-19 vaccine information were identified: processing new COVID-19 information in a health care work context likened to a "war zone" during the pandemic and communicating information to patients. Some providers were hesitant to recommend vaccines to pregnant people and groups they perceived to be at low risk for COVID-19.

CONCLUSIONS

Physicians have stronger trust in government sources and their employers for information about COVID-19 vaccines compared with nurses, pharmacists, and advanced practice providers. Strategies such as role modeling, tailored messaging, or talking points with standard language may help providers to communicate accurate COVID-19 vaccine information to patients, and these strategies may also be used with providers with lower levels of trust in reputable information sources.

An Update on the Pathogenesis of COVID-19 and the Reportedly Rare Thrombotic Events Following Vaccination

Today the coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has become a global health problem. After more than a year with the pandemic, although our knowledge has progressed on COVID-19, there are still many unknowns in virological, pathophysiological and immunological aspects. It is obvious that the most efficient solution to end this pandemic are safe and efficient vaccines. This manuscript summarizes the pathophysiological and thrombotic features of COVID-19 and the safety and efficacy of currently approved COVID-19 vaccines with an aim to clarify the recent concerns of thromboembolic events after COVID-19 vaccination. The influx of newer information is rapid, requiring periodic updates and objective assessment of the data on the pathogenesis of COVID-19 variants and the safety and efficacy of currently available vaccines.
