Factors affecting uptake of influenza vaccination among family physicians

ChatGPT Output Regarding Compulsory Vaccination and COVID-19 Vaccine Conspiracy: A Descriptive Study at the Outset of a Paradigm Shift in Online Search for Information

BACKGROUND

Being on the verge of a revolutionary approach to gathering information, ChatGPT (an artificial intelligence (AI)-based language model developed by OpenAI, and capable of producing human-like text) could be the prime motive of a paradigm shift on how humans will acquire information. Despite the concerns related to the use of such a promising tool in relation to the future of the quality of education, this technology will soon be incorporated into web search engines mandating the need to evaluate the output of such a tool. Previous studies showed that dependence on some sources of online information (e.g., social media platforms) was associated with higher rates of vaccination hesitancy. Therefore, the aim of the current study was to describe the output of ChatGPT regarding coronavirus disease 2019 (COVID-19) vaccine conspiracy beliefs. and compulsory vaccination.

METHODS

The current descriptive study was conducted on January 14, 2023 using the ChatGPT from OpenAI (OpenAI, L.L.C., San Francisco, CA, USA). The output was evaluated by two authors and the degree of agreement regarding the correctness, clarity, conciseness, and bias was evaluated using Cohen's kappa.

RESULTS

The ChatGPT responses were dismissive of conspiratorial ideas about severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) origins labeling it as non-credible and lacking scientific evidence. Additionally, ChatGPT responses were totally against COVID-19 vaccine conspiracy statements. Regarding compulsory vaccination, ChatGPT responses were neutral citing the following as advantages of this strategy: protecting public health, maintaining herd immunity, reducing the spread of disease, cost-effectiveness, and legal obligation, and on the other hand, it cited the following as disadvantages of compulsory vaccination: ethical and legal concerns, mistrust and resistance, logistical challenges, and limited resources and knowledge.

CONCLUSIONS

The current study showed that ChatGPT could be a source of information to challenge COVID-19 vaccine conspiracies. For compulsory vaccination, ChatGPT resonated with the divided opinion in the scientific community toward such a strategy; nevertheless, it detailed the pros and cons of this approach. As it currently stands, the judicious use of ChatGPT could be utilized as a user-friendly source of COVID-19 vaccine information that could challenge conspiracy ideas with clear, concise, and non-biased content. However, ChatGPT content cannot be used as an alternative to the original reliable sources of vaccine information (e.g., the World Health Organization [WHO] and the Centers for Disease Control and Prevention [CDC]).

Factors influencing healthcare professionals' confidence in vaccination in Europe: a literature review

Health-care professionals (HCPs) have a fundamental role in vaccination, their own beliefs and attitudes affecting both their uptake and recommendation of vaccines. This literature review (n = 89) summarises evidence on HCPs’ perceptions of the risks and benefits of vaccination, trust, and perceptions of mandatory vaccination in Europe. HCPs across studies believed that vaccination is important to protect themselves and their patients. However, beliefs that some diseases such as influenza are less risky were reported by some HCPs as a reason for not getting vaccinated. Concerns about both short- and long-term side effects were identified among HCPs in most studies, such as those affecting the immune or neurological system. Mistrust toward health authorities and pharmaceutical industry was reported in some studies. The question of mandatory vaccination revealed mixed opinions, with some favoring self-determination and others viewing vaccination as a duty. This review highlights key factors influencing HCPs’ confidence in vaccination in Europe.

A mixed methods study of health care professionals’ attitudes towards vaccination in 15 countries

Background

Health care professionals are widely considered to be the most trusted source of information on vaccine-related topics. However, several are reporting their own hesitancy around certain vaccines, influencing their intention to vaccinate themselves as well as influencing their recommendations to their patients and target population.

Methods

A mixed-methods approach was used including an online survey (n = 1,504) in 15 countries which aimed to determine drivers of HCPs vaccine confidence and examine how these drivers vary across nations. Thirty in-depth semi-structured interviews were conducted with 10 HCPs in a subset of three countries (France, Greece and Hungry) to explore barriers to HCPs vaccine uptake and their role in addressing vaccine hesitancy among patients.

Findings.

The survey’s regression analysis identified that nurses/midwives and HCPs from Hungary, Italy, Romania and Switzerland were less confident in the safety, importance or effectiveness of vaccines in general. Morocco (35%), Turkey (53%) and Greece (69%) reported the lowest influenza vaccination coverage among HCPs. Morocco also reported the lowest rates of HCPs who were “highly likely” to recommend MMR vaccine (34%), HPV vaccine (31%) and Covid-19 vaccines (29%). More than third of HCPs reported a lack of trust in health authorities and in the information they provide. Thematic analysis revealed that concerns over the risk of side-effects associated with vaccines, preference for natural immunity, whether it was necessary to be vaccinated against influenza every year, not having any chronic disease risk factors, and vaccines mandates as the key barriers to HCPs vaccination against influenza and Covid-19.

Conclusion

HCPs have an important role in vaccination and their confidence in vaccination and health authorities must be improved as this may affect their uptake of vaccines and influence their recommendations to their patients. Investigating the impact of political, socio-economic and cultural contexts on concerns about vaccination among HCPs is also necessary.

Secondary School Teachers and Outpatient Physicians: Differences in Attitudes towards Vaccination against COVID-19 in Slovakia

The aim of this study was to evaluate the differences in attitudes towards vaccination against COVID-19 among secondary school teachers and outpatient physicians. A cross-sectional study was realised using anonymous questionnaires. The EPI Info 7 program and R software, version 4.0.2 were used for statistical analysis. The questionnaire was completed by 868 respondents (teaching staff N = 451; outpatient physician N = 417). The number of employees vaccinated against COVID-19 was 742 (85.5%). The number of those vaccinated against COVID-19 and influenza (last season) was 192 (21.9%). The statistically significant predictors were the level of fear of COVID-19 (OR 1.40; 95% CI 1.29-1.52), profession-outpatient physicians (OR 2.56; 95% CI 1.55-4.23), history of COVID-19 (OR 0.34; 95% CI 0.22-0.54), gender (OR 0.55; 95% CI 0.33-0.89) and influenza vaccination at any time in the past (OR 3.52; 95% CI 1.10-11.31). The strongest motivation for vaccination against COVID-19 among physicians was the prevention of the spread of COVID-19 during the performance of their profession (N = 336; 87%); among teachers, it was the protection of family members (N = 258; 73%). The most common reason for vaccine hesitancy was concern about vaccine safety (N = 80; 63.5%).

Understanding Primary Care Physician Vaccination Behaviour: A Systematic Review

BACKGROUND

Vaccine hesitancy decreases adult vaccination coverage and has been recognized by WHO as a major health threat. Primary care physicians (PCP) play a key role in vaccination by giving vaccine counselling to their patients. The aim of this systematic review is to identify the knowledge, beliefs, attitudes and barriers (KBAB) associated with own vaccination and patient recommendation in primary care physicians.

METHODS

MEDLINE/PubMed, EMBASE and Cochrane Library databases were used to search and identify relevant studies based on their title and abstract. In the next step, the full text of each previously selected article was read for eligibility. Articles were selected by two independent reviewers and data extraction was performed using tables. The following information was extracted: methodological characteristics, demographic factors, professional characteristics, and intrinsic or extrinsic factors influencing vaccination or recommendation.

RESULTS

Our search yielded 41 eligible papers, data-sources, previous practices, belief in the effectiveness or safety of the vaccine, perceived risk, and trust in health authorities were all shown to be related to own vaccination and patient recommendation.

CONCLUSION

Internet is the main source of information for PCP related to vaccine hesitancy. It is therefore essential to increase the presence and access to pro-vaccination content in this area. In addition, involving PCP in the establishment of vaccination recommendations could improve their credibility in the institutions. On the other hand, training in communication skills and establishing reminder systems could reflect higher vaccination coverage among their patients.

The Role of Psychological Factors and Vaccine Conspiracy Beliefs in Influenza Vaccine Hesitancy and Uptake among Jordanian Healthcare Workers during the COVID-19 Pandemic

Vaccination to prevent influenza virus infection and to lessen its severity is recommended among healthcare workers (HCWs). Health professionals have a higher risk of exposure to viruses and could transmit the influenza virus to vulnerable patients who are prone to severe disease and mortality. The aim of the current study was to evaluate the levels of influenza vaccine acceptance and uptake as well as its determinants, among Jordanian HCWs over the last influenza season of 2021/2022. This study was based on a self-administered electronic survey that was distributed in March 2022. Psychological determinants of influenza vaccine acceptance and vaccine conspiracy beliefs were assessed using the previously validated 5C scale questionnaire (confidence, complacency, constraints, calculation and collective responsibility) and the vaccine conspiracy beliefs scale. The study sample comprised a total of 1218 HCWs: nurses (n = 412, 33.8%), physicians (n = 367, 30.1%), medical technicians (n = 182, 14.9%), pharmacists (n = 161, 13.2%) and dentists (n = 87, 7.1%), among others. About two-thirds of the study sample expressed willingness to receive influenza vaccination if provided free of charge (n = 807, 66.3%), whereas less than one-third were willing to pay for the vaccine (n = 388, 31.9%). The self-reported uptake of the influenza vaccine in the last influenza season was 62.8%. The following factors were significantly associated with higher acceptance of influenza vaccination if provided freely, as opposed to vaccine hesitancy/rejection: male sex; physicians and dentists among HCW categories; higher confidence and collective responsibility; and lower complacency, constraints and calculation. Higher influenza vaccine uptake was significantly correlated with nurses and physicians among HCW categories, older age, a higher monthly income, higher confidence and collective responsibility, lower complacency and constraints and lower embrace of general vaccine conspiracy beliefs. The results of the current study can provide helpful clues to improve influenza vaccine coverage among HCWs in Jordan. Consequently, this can help to protect vulnerable patient groups and reserve valuable resources in healthcare settings. Psychological determinants appeared to be the most significant factors for vaccine acceptance and uptake, whereas the embrace of general vaccine conspiracy beliefs was associated with lower rates of influenza vaccine uptake, which should be considered in educational and interventional measures aiming to promote influenza vaccination.

A comprehensive review of drivers influencing flu vaccine acceptance in the Middle East over the last six years: using Health Belief Model

OBJECTIVES

The objectives of this study were to review the literature covering the perceptions about influenza vaccines in the Middle East and to determine factors influencing the acceptance of vaccination using Health Belief Model (HBM).

METHODS

A comprehensive literature search was performed utilizing PubMed and Google Scholar databases. Three keywords were used: Influenza vaccine, perceptions and Middle East. Empirical studies that dealt with people/healthcare worker (HCW) perceptions of influenza vaccine in the Middle East and written in English were included. The search covered articles published between January 2015 and November 2020.

KEY FINDINGS

A total of 34 cross-sectional studies covering a total of 35 518 participants from 22 countries were included in this review. The overall influenza vaccination rates were generally low (<50%) among general population, particularly among pregnant women and children. HCWs had relatively higher vaccination rates compared with general population. Old age, health comorbidities or working in high-risk environments were noted as major motivators to receive the vaccine. Concerns about adverse reactions and the lack of vaccine efficacy were the most predominant reported barriers to receiving the vaccines. Lastly, cues to actions included receiving advice from HCWs, influence of institutional requirement, awareness/educational pamphlets and influence from the media.

SUMMARY

The HBM can be helpful in identifying and analysing motivators and barriers to vaccination. Additionally, by looking at the root causation, this model can help plan campaigns to increase vaccination rates in the region. Finally, we recommend empowering HCWs to proactively advocate for vaccination as part of preventive care.

Determinants of seasonal influenza vaccination hesitancy among healthcare personnel: An integrative review

AIMS AND OBJECTIVES

To explore the determinants of and behaviour change models for seasonal influenza vaccination compliance among healthcare personnel.

BACKGROUND

COVID-19 vaccine hesitancy among healthcare personnel may be better understood by exploring determinants of seasonal influenza vaccine hesitancy.

DESIGN

Integrative literature review.

METHODS

A systematic search was conducted in accordance with PRISMA guidelines. Six thousand and forty-eight articles were screened. Seventy-eight met inclusion criteria. Due to the heterogeneity of included articles, a narrative synthesis was conducted utilising a conceptual matrix to identify thematic categories.

RESULTS

Six thematic categories were identified as influencing HCP SIV compliance: 'perceived vulnerability', 'trust', 'past behaviour', 'professional duty', 'access and convenience' and 'knowledge and experience'. The Health Belief Model (HBM) was the most commonly utilised health behaviour change model within the seasonal influenza vaccination context. Few studies have examined seasonal influenza vaccine acceptance and uptake within the Australian HCP context, particularly involving community care and aged care.

CONCLUSIONS

Factors that appear to relate to influenza vaccination compliance among HCP can be grouped according to several thematic categories, and they also appear influential in COVID-19 vaccine uptake. In particular, an emerging focus on 'trust' or the more emotive considerations of decision-making around health-protective behaviours requires further exploration in the context of a pandemic. Efforts to influence these domains to increase compliance, however, are likely to be impeded by a lack of a well-developed and tested behaviour change model.

RELEVANCE TO CLINICAL PRACTICE

Healthcare personnel (HCP) face high levels of occupational exposure to seasonal influenza every year. An emerging focus on 'trust' and the more emotive considerations of decision-making around health-protective behaviours requires further exploration in the context of a pandemic.

Healthcare Workers' (HCWs) attitudes towards mandatory influenza vaccination: A systematic review and meta-analysis

Influenza is a disease responsible for thousands of deaths every year. Although healthcare workers (HCWs) represent a way of contagion for patients, vaccination coverage among them is low. Mandatory vaccination has been proposed, but controversies remain. This systematic review and meta-analysis aimed to assess the acceptance of mandatory vaccination by HCWs, and to investigate associated characteristics. MEDLINE, Scopus, Embase, PsycInfo, CINAHL and Web of Science were used to search for studies assessing the topic. PRISMA statements were followed. Of the 13,457 univocal records found, 52 studies were included in the systematic review and 40 in the meta-analysis. The pooled proportion of HCWs accepting the policy was of 61% (95% CI: 53%- 68%) but with great heterogeneity between continents (from 54% in Europe to 69% in Asia) and in different professionals (from 40% in nurses to 80% in students). Vaccinated HCWs agreed more frequently with mandatory vaccination than non-vaccinated ones. More studies that consider mandatory vaccination acceptance as the main outcome are needed, but the results of this study confirm that in some settings the majority of HCWs favour mandatory vaccination. This, combined with effects that a flu epidemic could have if overlapped to pandemics with similar symptoms, requires renewed considerations on mandatory vaccination.

Vaccination attitudes, beliefs and behaviours among primary health care workers in northern Croatia

Primary health care workers (HCWs) provide almost all vaccine services in Croatia, so they play an essential role in vaccine recommendations and uptake. The aim of this study was to determine the level of vaccine hesitancy among primary HCWs, to identify differences between nurses and physicians in attitudes, beliefs and behaviours towards vaccination, and to determine predictors of vaccine hesitancy among HCWs. We conducted a cross-sectional study from July to December in 2018 among physicians and nurses employed in the services of epidemiology, public health, school medicine, pediatrics and general practice/family medicine in Primorje-Gorski Kotar County, a primarily urban region with a population around 300 000 in the northern part of Croatia. The list of primary HCWs offices was obtained from the Croatian Health Insurance Fond website. We used a self-administered questionnaire on their attitudes, beliefs and behaviours relative to vaccination. Obtained response rate was 65.5% (324/495) of eligible primary HCWs; 64.1% (143/223) of physicians and 66.5% (181/272) of nurses. Seventeen percent of HCWs were identified as vaccine hesitant, and in univariate analysis, we observed an association between HCWs occupation and their own vaccination against flu (p = 0.001), measles (p = 0.016) and HPV (p = 0.025). Nurses and physicians differed (p < 0.001) in their general attitude, beliefs and behaviours towards vaccination, with a higher level of hesitancy among nurses. In multiple logistic regression, those more likely to be vaccine-hesitant were nurses (AOR = 5.73, 95%CI = 2.48-13.24), those who were uncertain or would never receive a vaccine against measles (AOR=11.13; 95%CI=5.37-23.10) and HPV (AOR=5.02; 95%CI=2.60-9.74), as well as those who had encountered a serious adverse event following immunization (AOR=7.55; 95%CI=3.13-19.18). As personal hesitancy may have a negative impact on vaccination education and recommendations, and therefore vaccine coverage, it is necessary to implement interventions to increase vaccination knowledge and confidence among primary health care workers, especially nurses.

Determinants of Vaccination Uptake in Risk Populations: A Comprehensive Literature Review

Vaccination uptake has decreased globally in recent years, with a subsequent rise of vaccine-preventable diseases. Travellers, immunocompromised patients (ICP), and healthcare workers (HCW) are groups at increased risk for (severe) infectious diseases due to their behaviour, health, or occupation, respectively. While targeted vaccination guidelines are available, vaccination uptake seems low. In this review, we give a comprehensive overview of determinants-based on the integrated change model-predicting vaccination uptake in these groups. In travellers, low perceived risk of infection and low awareness of vaccination recommendations contributed to low uptake. Additionally, ICP were often unaware of the recommended vaccinations. A physician's recommendation is strongly correlated with higher uptake. Furthermore, ICP appeared to be mainly concerned about the risks of vaccination and fear of deterioration of their underlying disease. For HCW, perceived risk of (the severity of) infection for themselves and for their patients together with perceived benefits of vaccination contribute most to their vaccination behaviour. As the determinants that affect uptake are numerous and diverse, we argue that future studies and interventions should be based on multifactorial health behaviour models, especially for travellers and ICP as only a limited number of such studies is available yet.

Beliefs, attitudes, and activities of healthcare personnel about influenza and pneumococcal vaccines

OBJECTIVES

Vaccination of healthcare personnel (HCP) is an effective measure for preventing the spread of influenza among at-risk patients. This study was conducted to determine influenza vaccination rates and activities among HCP working at a tertiary healthcare setting.

METHODS

This study included 470 HCP (85 physicians, 134 nurses, 53 healthcare assistants, 44 paramedics, 47 medical secretaries, and 107 auxillary staff members) working at the emergency, cardiology, chest diseases, and internal medicine departments with the largest volume of patients with vaccination indication of two large university hospitals with similar medical practices and work environment. Each participant completed an anonymous questionnaire form.

RESULTS

A total of 470 HCP participated in the survey. The compliance rate of the HCP to participate in the survey was 93.6%. Of these, 26.7% had been vaccinated against influenza. Vaccination in the survey year was significantly associated with having regular influenza vaccinations (OR 48.66; 95% CI:[25.09-94.369]; P<.01); having an educational level of college or higher (OR 2.07; 95% CI:[1.03-4.15]; P<.05); being a physician (OR 4.25; 95% CI:[1.28-14.07]; P< .05); and a professional experience of more than 5 years (OR 2.02; 95%CI:[1.13-5.62]; P< .05). Physicians recommended and prescribed the influenza vaccine significantly more frequently than the pneumococcal vaccine (37.6% vs 30.6%, P = .03, 25.9% vs 17.6%, P = .001, respectively). Among all HCP, the reasons for vaccination included having the opinion that the vaccine provides a partial protection against the infection (75.2%), reduces work force loss (48.8%), reduces the rates of death and severe conditions like pneumonia (43.2%), and reduces hospitalization (40.8%). The HCP had been vaccinated to protect family members (81.6%), people around (51.2%), herself/himself (47.2%), and patients (28%) fom infection. The reasons of not getting vaccinated against influenza among HCP included fear of vaccine's adverse effects (31.0%), doubts about its efficacy (28.9%) and safety (22.3%), and lack of adequate knowledge about vaccination (16.2%).

CONCLUSION

Our results indicated that influenza vaccination rates are low in our whole HCP sample, with physicians having a slightly better rate than other HCP. Getting regularly vaccinated, having an educational level of college or higher, being a physician, and having a professional experience of more than 5 years positively affects the rate of future vaccinations. Physicians significantly more commonly recommended and prescribed the influenza vaccine than the pneumococcal vaccine. The most important reasons for getting vaccinated included having the opinion that the vaccine provided partial protection and intending to protect family members from infection. In our whole HCP sample, the reasons of not getting vaccinated against influenza included fear of vaccine's adverse effects and doubts about its efficacy and safety. Training meetings should be held for HCPs to underscore the importance of the influenza vaccine for protection of patients against the influenza.
