“…It also follows from the flow diagram that the system of differential equations governing the epidemic dynamic system satisfies: The interpretation of each parameter is given in Table 1. The model is a generalization of the classical SEIR deterministic model and is adopted from Oduro et al (2021). One main distinction from their work is that we assume that both recovery and vaccines provide immunity against the disease only for a limited period.…”

Rapid rollouts of the vaccine are imperative for economic recovery; however, vaccine hesitancy could draw out not only the pandemic but also social distancing and lockdown requirements. The main purpose of this paper is to empirically investigate whether the vaccination rate affects government budget constraints as well as whether vaccine hesitancy matters in controlling the dynamics of the Covid-19 epidemic in Uzbekistan. We integrated a Susceptible-Exposed-Infectious-Removed (SEIR) epidemic model with a macroeconomic model to explore the impact of the vaccination. Our results show that vaccine hesitancy substantially influences excess COVID-19-related deaths, such that governments that are able to sustain quick vaccine rollout rates would have a 20-times lower excess death rate. A slow-paced vaccine rollout has compounded effects over time, producing much heavier consequences for the population than a rapid rollout rate. In Uzbekistan, a counterfactual exercise that intensified vaccine hesitancy between April and November 2021 likely increased the death toll by approximately thousand deaths. Therefore, the policy gains of accelerating the vaccination rate are significant, given that it would minimize both cumulative mortality and the risk of new virus variants while achieving herd immunity. Concurrently, efforts to mitigate hesitancy are crucial, particularly if the percentage of the population that is against the vaccination is greater than the percentage needed for herd immunity. To this end, our empirical study helps shed light on the challenging dynamics between health and the economy during the pandemic as well as the mechanisms through which these effects take place.

“…Therefore, it is in our view that religious people could believe more in conspiracy theories about vaccines and vaccination and could also believe that others are more prone to be influenced by other external factors, media included. While vaccine education can significantly decrease vaccine hesitancy rates (Oduro et al, 2021), education has been proved to be a predictor of TPE: when it comes to the ability to detect fake news, educated people perceive a greater gap between themselves and others (Corbu et al, 2020b, p. 11). Thus, TPE appears to be stronger in better educated individuals (Salwen, 1998).…”

PurposeThe present study aims to unveil the main predictors of perceived media influence (the third-person effect (TPE)) on people's opinions towards COVID-19 vaccination. While the TPE has been researched before in medical contexts, predictors of TPE on the topic of vaccination against COVID-19 are understudied.Design/methodology/approachThis study employs a national survey using an online panel (N = 945) representative for the online population of Romania aged 18 or higher; data were collected during 1–9 April 2021.FindingsResults indicate that people perceive both close and distant others to be more influenced by media information related to COVID-19 vaccination topics. TPE perception is correlated with belief in conspiracy theories about vaccines/vaccination, perceived incidence of fake news about COVID-19 vaccines/vaccination, perceived usefulness of social networking sites and critical thinking.Originality/valueResults from this study might explain the success rate of some communication strategies employed with the help of the media. Key findings could be used as starting points for understanding the profile of those who underestimate the media's impact on themselves with respect to COVID-19 immunization and for designing more successful media strategies.

“…For instance, 38% of those interviewed in France were hesitant toward COVID-19 vaccine where 10% were opposed to COVID-19 vaccination while the remaining 28% were undecided about getting COVID-19 vaccination [33]. In the United States (US), a report by the American Medical Association Journal hinted that skepticism toward vaccines that were being administered was on the rise [35]. This was further corroborated by the Kaiser Family Foundation COVID-19 vaccine monitoring which indicated that approximately 29% of health practitioners were reluctant to accept the vaccine [36].…”

“…Shortly after WHO and Center for Disease Control (CDC) declared availability of COVID-19 vaccines, several epidemiological mathematical frameworks began to emerge with the aim of investigating whether vaccines will slow or end the COVID-19 pandemic as well as determining strategies that ensured optimal distribution of COVID-19 vaccines [41][42][43][44]. In the sequel, few epidemiological mathematical models have attempted to elucidate on the impact vaccine hesitancy played in the early roll-out of COVID-19 vaccines [33,35]. Some pertinent questions that relate to vaccine hesitancy have been investigated as far as COVID-19 vaccine roll-out is concerned.…”

IntroductionThe unexpected emergence of novel coronavirus identified as SAR-CoV-2 virus (severe acute respiratory syndrome corona virus 2) disrupted the world order to an extent that the human activities that are core to survival came almost to a halt. The COVID-19 pandemic created an insurmountable global health crisis that led to a united front among all nations to research on effective pharmaceutical measures that could stop COVID-19 proliferation. Consequently, different types of vaccines were discovered (single-dose and double-dose vaccines). However, the speed at which these vaccines were developed and approved to be administered created other challenges (vaccine skepticism and hesitancy).MethodThis paper therefore tracks the transmission dynamics of COVID-19 using a non-linear deterministic system that accounts for the unwillingness of both susceptible and partially vaccinated individuals to receive either single-dose or double-dose vaccines (vaccine hesitancy). Further the model is extended to incorporate three time-dependent non-pharmaceutical and pharmaceutical intervention controls, namely preventive control, control associated with screening-management of both truly asymptomatic and symptomatic infectious individuals and control associated with vaccination of susceptible individuals with a single dose vaccine. The Pontryagin's Maximum Principle is applied to establish the optimality conditions associated with the optimal controls.ResultsIf COVID-19 vaccines administered are imperfect and transient then there exist a parameter space where backward bifurcation occurs. Time profile projections depict that in a setting where vaccine hesitancy is present, administering single dose vaccines leads to a significant reduction of COVID-19 prevalence than when double dose vaccines are administered. Comparison of the impact of vaccine hesitancy against either single dose or double dose on COVID-19 prevalence reveals that vaccine hesitancy against single dose is more detrimental than vaccine hesitancy against a double dose vaccine. Optimal analysis results reveal that non-pharmaceutical time-dependent control significantly flattens the COVID-19 epidemic curve when compared with pharmaceutical controls. Cost-effectiveness assessment suggest that non-pharmaceutical control is the most cost-effective COVID-19 mitigation strategy that should be implemented in a setting where resources are limited.DiscussionPolicy makers and medical practitioners should assess the level of COVID-19 vaccine hesitancy inorder to decide on the type of vaccine (single-dose or double-dose) to administer to the population.
