DESIGN: A cross‐sectional, structured questionnaire was utilized for this investigation in September 2021, during the fourth wave of the pandemic. METHODS: A sample of the adult (18+) Israeli population was employed for the study. Recruiting participants for the study was conducted through an online internet panel company that consists of over 100,000 members, representing all geographic and demographic sectors of the Israeli population. RESULTS: Our findings indicate that pandemic fatigue has begun to have cascading effects on vaccination efforts. In particular, this study found that at this stage of the COVID‐19 pandemic, trust in authorities, and even threat perception components, such as concern and fear of contracting the disease, are incapable of predicting vaccination uptake. Instead, perception of the importance of the vaccine and its effectiveness are predictive of vaccination uptake. CONCLUSION: The findings indicate that at this stage of the pandemic, focusing on the robustness of the science behind the vaccine is more important than trying to regain public trust. The findings also suggest that risk communication employing fear tactics is losing its capacity to generate motivation for vaccination. CLINICAL RELEVANCE: The findings of this study reveal lessons learned from the COVID‐19 global pandemic. Specifically, the study reveals how in times of prolonged crisis, we can currently and, in the future, prepare improved strategies for public communication in order to promote uptake of protective health behavior, such as vaccination. Since the onset of the coronavirus disease 2019 (COVID-19) pandemic, a variety of policies have been enacted by governments worldwide in an effort to contain the outbreak (Hale et al., 2021) . Early in the pandemic, prior to the extensive availability of vaccines, governments relied on non-pharmaceutical interventions (NPIs) to reduce virus transmission within their respective populations with the aim of delaying the timing of the epidemic peak (Flaxman et al., 2020; Lai et al., 2020) . Health measures focused on minimizing interpersonal contact to reduce the risk of person-to-person transmission, through mobility restrictions, mask wearing, and social distancing (such as school closures and gathering bans), alongside strategies of testing and contact tracing (Flaxman et al., 2020; Lai et al., 2020) . While the stringency of measures has varied throughout the outbreak and across geographical regions, the measures have been in place in many countries, for well over a year (Hale et al., 2021) . Alongside multi-pronged countermeasures, vaccination rollout campaigns were integrated in late 2020 in order to suppress COVID-19 transmission (Shilo, Rossman, & Segal, 2021) . In the case of Israel, a country of 9.3 million, a supply of the Pfizer-BioNTech vaccine was obtained and inoculation began on December 20, 2020 among healthcare staff, individuals aged 60 years and older, and those with additional risks (e.g., immunodeficiency, chronic lung disease, diabetes, etc.) and gradually expanded to include all eligible individuals (including most recent children over the age of 5 on November 23, 2021) (Alpert, Herbst, Abramovich, Strugo, & Jaffe, 2021; Wilf-Miron, Myers, & Saban, 2021) . The vaccination drive was orchestrated by the Ministry of Health and conducted by four national health maintenance organizations (HMOs), which provide insurance for all citizens and ensured easy access throughout the country (Alpert et al., 2021; Wilf-Miron et al., 2021) . Despite early success and momentum in the vaccination campaign, a moderate, yet the notable level of vaccine hesitancy in the Israeli general population was observed (Dror et al., 2020) . Globally, widespread immunization has been hampered by the reluctance of large sectors of the public to receive recommended available vaccines which, in part may be due to the fast-tracked new technology involved with the development of COVID-19 vaccines, and these, along with the well-established concerns of vaccine opponents (Wilf-Miron et al., 2021) . This phenomenon may be propagated by a spectrum of held views concerning vaccination, spanning from vigilant acceptors to complete deniers (Rosen, Waitzberg, Israeli, Hartal, & Davidovitch, 2021) . Anti-vaccination groups with a strong social media platform presence have contributed to growing anxieties concerning vaccination worldwide (Rosen et al., 2021) . To incentivize vaccination in an attempt to reach "herd immunity," Israel, had implemented a "green pass" certificate which would provide access to social, cultural, sports events, gyms, hotels, and restaurants. It also provides exemptions from isolation upon contact with a confirmed COVID-19 case or upon returning from international travel for those who were deemed to have achieved "immunity," whether based on those who had recovered from COVID-19 or by being fully vaccinated (Wilf-Miron et al., 2021) . In spite of progress in clinical care for patients and findings in Israel and around the globe indicating the effectiveness of the vaccine through the marked declines in the incidence of SARS-CoV-2 infections, hospitalizations, and deaths, as presented by Haas et al. (2021) , the management of the pandemic, has been aggravated by the findings that vaccinated individuals can serve as asymptomatic carriers, the evolution and emergence of new, highly transmissible variants (such as the Delta and Omicron variants), alongside the hurdles of different durations of effective immunity or "time-limited immunity" (Haas et al., 2021; Kosinski, 2020; Puri, Coomes, Haghbayan, & Gunaratne, 2020; Reis et al., 2021) . These elements may play a contributing factor in vaccine hesitancy and disbelief in the efficacy of the vaccine. Following the notable decline in immune protection following the two-dose regime, the health authorities in Israel launched a campaign for vaccinating all those eligible with a third "booster" shot after a 5-month elapsed period from the second dose of inoculation (Mahase, 2021a; Mahase, 2021b; Porat et al., 2021) Currently, discussions are underway in the government regarding a population-wide fourth dose vaccination drive (Times of Israel, 2021). Other countries have similarly provided incentive schemes for the public to vaccinate, where governments have proposed or implemented "digital health passes" to provide proof of vaccination and allow for a gradual reopening of the economy, where key sectors such as food, retail, entertainment, and travel could be reinvigorated (Dror et al., 2020; Wilf-Miron et al., 2021) . Some states and countries such as Indonesia, Greece, and Austria, while morally and ethically problematic, have invoked vaccination mandates (Gostin, Cohen, & Shaw, 2021; The Guardian, 2021) . . As the 2-year mark has approached since the commencement of the COVID-19 pandemic (November 2019) during which a "wax and wane" battle trajectory has been observed almost globally and afflicted most of the human-life domains, the concept of "pandemic fatigue" has gained both academic and popular lexicon traction. Pandemic fatigue defined by the WHO as "distress which can result in demotivation to follow recommended protective behaviors, emerging gradually over time and affected by a number of emotions, experiences, and perceptions" has been identified as an additional hurdle and risk factor to adherence to health-protective behavior by the public (Ala'a, Tarhini, & Akour, 2021). Given the ability to continue to mitigate adverse consequences of the pandemic relies on the public's compliance with health regulations, the phenomenon may have implications for jeopardizing the epidemiological status curves of countries (Ala'a et al., 2021; Bodas & Peleg, 2021) . To achieve public health benefits from the various implemented measures, the public's cooperation is crucial (Bodas & Peleg, 2021; Kaim et al., 2021b; Kaim, Jaffe, Siman-Tov, Khairish, & Adini, 2020) . Throughout various phases of the pandemic, it has been identified that among various additional factors-trust, perceived fear, susceptibility, severity of disease, and efficacy of measures play a key role in the mediation process of compliance to protective behavior (Bodas & Peleg, 2020; Kaim et al., 2020; Kaim et al., 2021a; Seale et al., 2020) . In the context of Israel, as described by Bodas and Peleg (2021) , the various measures taken by the government such as prolonged shutdowns of businesses and school systems and confinements of people to their homes have taken a substantial toll on the public. In light of this information and the evolving conditions of the pandemic, understanding the public's mediation process of compliance to directed protective behavior alongside receptivity of a booster vaccine is essential for the purpose of mitigating the consequences of this ongoing emergency and future such outbreaks. The purpose of the current study was to examine the factors that impact vaccination uptake and additional protective behavior through a cohort study assessing public attitudes during the fourth wave of the pandemic in Israel. The study was conducted during the fourth wave of the pandemic in Israel, in September 2021. A sample of the Israeli population (N = 940) was employed to assess uptake of the third dose of the vaccine (booster) as well as factors implicated in compliance. Recruiting participants for the study was conducted through iPanel, an online internet panel company that consists of over 100,000 members, representing all geographic and demographic sectors of the Israeli population. A stratified sampling method was used, based on data published by the Israeli Central Bureau of Statistics in regard to age, gender, religiosity, and geographic zones. The sample size was determined based on The OpenEpi online calculator (https://www.opene pi.com/Sampl eSize), requiring 384 respondents. This was calculated based on the size of the Israeli population, accounting for 9.3 million people, as presented by the Israeli Bureau of Statistics. The study was conducted using a random internet sample of 940 participants who consented to participate voluntarily in the research. To partake in the study, the participants had to confirm their willingness to voluntarily participate in the study. The data were collected anonymously, following the approval of the Ethics Committee of the Tel Aviv University (number 0003846-1 from September 2, 2021). The study was based on a structured questionnaire that included items and indices that were developed specifically for this study, given no prior work had evaluated vaccine uptake for a third dose, as was the case in Israel. The newly developed components of the questionnaire were designed based on a literature review conducted as well as consultation with experts in the field of the behavior of civil society. The questionnaire was validated by five content experts and pilot tested on 20 individuals prior to its dissemination. Attitudes toward COVID-19/vaccine One item assessed concern regarding the coronavirus ("To what extent are you concerned about the coronavirus outbreak?") on a 5-point Likert scale, from 1 = not at all, to 5 = to a very large extent. One item assessed apprehension from getting infected with the coronavirus ("How afraid are you to be infected with the coronavirus?") on a 5-point Likert scale, from 1 = to a very small extent, to 5 = to a very large extent). Four items assessed perceived personal threats from the economic, health, security, and political situation in Israel Descriptive statistics were used to analyze the characteristics of the sample. Chi-square tests were used to evaluate the association between vaccine uptake and threat perception and attitudes toward COVID-19. Ordinal logistic regression was used for determining the factors affecting vaccination. ANOVA test was used to identify variability between vaccination groups (No dose, 1 dose, two doses, three doses of inoculation). All statistical analyses were performed using SPSS software version 27. p-values lower than 0.05 were considered to be statistically significant. The final sample for this study included 940 participants, of which 50.6% (n = 476) were females. The mean age of participants was 40.41 years (14.47 SD), with a minimum age of 18 and maximum age of 70. One hundred thirty-seven participants (14.6%) reported they were confirmed COVID-19 cases. The complete socio-demographic breakdown of the sample is provided in Table The results indicate that vaccination uptake is negatively associated with the level of religiosity. Among those vaccinated with three doses, half defined themselves as secular, and half as non-secular (religious and traditional). However, among those vaccinated with two doses and those who are unvaccinated, non-secular individuals account for 63% and 74%, respectively (χ 2 = 24.58, df = 2, p < 0.001). The higher level of education is associated with vaccination uptake, as well. The ratio of academics to non-academics among those vaccinated with three doses is 55%-45%, respectively, whereas among those vaccinated with two doses this ratio changes to 46%-54%, and among unvaccinated individuals, the representation is 30% academics versus 70% non-academic (χ 2 = 23.81, df = 2, p < 0.001). Furthermore, unvaccinated individuals also reported lower income compared to the vaccinated groups (data not shown). As expected from their relative distribution in the Israeli population, in all three vaccination uptake groups, the portion of Jews is larger than that of the Arab population. However, as the vaccination uptake increases, the relative portion of the The fourth wave of the COVID-19 outbreak in Israel and the massive "booster" vaccination campaign provided a valuable setting for evaluating the effect of the pandemic fatigue on compliance with vaccination. At the time of conducting the study, the virus has impacted Israeli and global communities for close to 2 years. As Israel was the first country to initiate a massive "booster" vaccination campaign, this investigation offers the setting of evaluating the pandemic fatigue effect on vaccination efforts. In this study, we show that vaccine hesitancy remains to be a major barrier to full population inoculation, where even among those that received the initial two doses of the vaccine when asked about their willingness to receive a third booster dose, over 45% indicated they would probably not get it or said they will surely refuse it. Of those unvaccinated, over 75% indicated the same. Arguably, the vaccine hesitancy of the "booster vaccine" observed among those that received the initial two doses can be attributed to the "pandemic fatigue" phenomenon. In the context of this population, the reluctance perhaps does not reflect a conscious refusal of the vaccine as the previous inoculation was observed, but rather fatigue from the politicization of the issue where the swarming of arguments from both sides results in bewilderment and lack of uptake (Lewis, 2020) . As discussed by Lewis (2020) , the subject of the pandemic has become highly politicized, with partisanship impacting attitudes regarding uptake of protective behavior, the validity of COVID-19 statistics, as well as with respect to the development of the vaccine (Abbas, 2021) . Additionally, the booster vaccination campaigns may have predictably further heightened the resistance of individuals who are unvaccinated with initial doses turning them into "hard-core refusers" as the campaign may have brought into question the effectiveness of the vaccine in the first place (Hoffman, 2021) . In line with previous findings throughout the H1N1 pandemic and precursory stages of the COVID-19 outbreak (Al-Amer et al., 2022; Kaim et al., 2021b; Lazarus et al., 2021; Seale et al., 2010; Wang et al., 2020) , the bivariate analysis shows a significant association between vaccine uptake and threat perception of COVID-19, the political and economic situation, levels of trust in authorities, vaccine importance and uptake of additional health regulations and the perception of their efficacy. However, in the multivariate analysis, most of these associations are nullified where the predictors that remain are sociodemographic (age, religion, and academic status) and the perception of the importance and efficacy of the vaccine. These findings effectively demonstrate "pandemic fatigue" at play where the background noise about trust and fear tactics to motivate the public is no longer relevant. Instead, the findings indicate that at this stage of the pandemic, focusing on the robustness and the rigorous science behind the vaccine is more promising regarding effectiveness than trying to regain public trust. The findings also suggest that risk communication employment of fear tactics is losing its capacity to generate motivation for vaccination (Dermody et al., 2021) . As previously used effective messaging dwindles its influence on protective behavior, reinvigorating tactics must be sought after that identify priority population groups The scientific soundness of the vaccination, its efficacy and importance should be relayed to the public by trustworthy figures, namely physicians and researchers, as opposed to politicians and government representatives (Topf & Williams, 2021; Falcone & Sapienza, 2020) . As the pandemic becomes a chronic threat and is normalized into our daily lives, the type of information that interests the public changes as well. In earlier stages of the pandemic, information concerning preventive measures to avoid contracting the disease was most sought after (Sulistyawati et al., 2021) ; however, at this point in time, such information is less demanded by the public and attention to risk cues decreases, as is vivid in the reduction in levels of concern (author's unpublished data -under review This study offers important insights into understanding the mediation process of the public during a fourth wave of the COVID-19 ongoing crisis where the effects of pandemic fatigue have begun to cascade on vaccination efforts. In particular, this study found that fear and trust in authorities are no longer relevant for motivating uptake of vaccination, rather it is advisable that the evidence for the efficacy of the vaccine must be available and provided to the public. The socio-demographic predictor data also shows that sectors of the population are more hesitant than others, such as those of younger age, more religious backgrounds, and of non-academic status, and that targeted interventions for these populations must be considered to increase compliance with vaccination measures. This study has several limitations. First, this study employs the use of non-validated tools that were designed for the purpose of this research. Although efforts have been made to make the tool reliable through experts' consultations, the conclusions of this study should be taken with caution. Second, this study utilized an online panel to collect responses. While this option provides immediate access to a diverse sample of the population on a wide geographic distribution, it may limit the generalization of the conclusion to people with high digital literacy. Third, although this study was able to capture a sizeable portion of unvaccinated participants, it is difficult to assess whether or not these participants are representative of this group. It is reasonable to assume that additional archetypes of unvaccinated people may have been excluded from this study based on the enrollment process through an online panel. Lastly, a conclusion of the study was that younger age was associated with lower uptake of vaccination, however, it must be taken into consideration that young people started getting vaccinated at a later point in time due to the gradual opening of the vaccination campaign, thus fewer were eligible for a third vaccine at the time of the study, potentially impacting on our findings. The results of this study suggest that at the stage of the COVID-19 pandemic, characterized by pandemic fatigue, trust in authorities, and even threat perception components, such as concern and fear of contracting the disease, are incapable of predicting vaccination uptake. Instead, perception of the importance of the vaccine and its effectiveness are predictive of vaccination uptake. The findings indicate that at this stage of the pandemic, focusing on the robustness of the science behind the vaccine is more important than trying to regain public trust. The findings also suggest that risk communication employing fear tactics is losing its capacity to generate motivation for vaccination. ical-guida nce/2020/pande mic-fatig ue-reinv igora ting-the-publi c-to-preve nt-covid -19,-septe mber-2020-produ ced-by-whoeu rope This work did not receive any external funding.
