Sociodemographic and Psychological Predictors of Intention to Receive a COVID-19 Vaccine in Elderly Peruvians

Vaccine hesitancy: a structured review from a behavioral perspective (2015-2022)

Vaccine hesitancy, a complex behavioral phenomenon, poses a significant global health threat and has gained renewed attention amidst the COVID-19 pandemic. This paper scrutinized peer-reviewed literature on vaccine hesitancy published from 2015 to 2022, with a specific focus on behavioral perspectives, utilizing a Theories-Constructs-Variables-Contexts-Methods (TCVCM) framework. The study highlighted prominent theoretical approaches, abstract concepts, research variables, global contexts and academic techniques employed across a selected sample of 138 studies. The result is a consolidated overview of research and schematization of the factors influencing vaccine hesitancy and vaccination behaviors. These include individual-level, contextual, vaccine-specific, organizational, and public-policy-related dynamics. The findings corroborated the complexity of vaccine hesitancy and emphasized the difficulties of pursuing vaccine advocacy. The analysis also identified several directions for future research, and the need to conduct more contextual studies in low- and middle-income nations to bring out the cross-cultural nuances of vaccine hesitancy.

Vaccine Hesitancy and Its Epistemic Antecedents: A Meta-Analysis

Although much attention has been given to vaccine hesitancy, there is still considerable ambiguity regarding its epistemological antecedents. The current meta-analysis addresses this theoretical and practical gap by focusing on the interplay between trust, belief in conspiracy theories, and COVID-19 vaccine hesitancy (k = 32), as well as key moderators such as the availability of the vaccine and the state and progress of the pandemic. Overall, results indicate that while both trust and beliefs in conspiracy theories are important correlates of vaccine hesitancy, considerable difference emerges when adopting a more granular approach that distinguishes between types of trust (government, public health organizations, science, and healthcare professionals/providers) and conspiracies (specific versus general). These findings cement the importance of health communication, not only as a useful framework to study and understand vaccine hesitancy but also as a potential way to intervene in order to prepare for future infectious disease outbreaks.

Are the 7C psychological antecedents associated with COVID-19 vaccine behaviours beyond intentions? A cross-sectional study on at-least-one-dose and up-to-date vaccination status, and uptake speed among adults in France

BACKGROUND

Widely documented psychological antecedents of vaccination are confidence in vaccines, complacency, convenience, calculation, collective responsibility (5C model) with the recent addition of confidence in the wider system and social conformism. While the capacity of these seven antecedents (7C) to explain variance in COVID-19 vaccine intentions has been previously documented, we study whether these factors also are associated with vaccine behaviours, beyond intentions.

METHODS

From February to June 2022, we recruited a sample of adults in France, including persons with notified recent SARS-CoV-2 infection, along with relatives and randomly selected non-infected persons. Participants completed self-administered questionnaires assessing COVID-19 vaccination history and the 7C antecedents. We defined vaccination behaviours as three outcomes: at-least-one-dose vaccine status by 2022 (N = 49,019), up-to-date vaccination status (N = 46,566), and uptake speed of first dose (N = 25,998). We conducted multivariable logistic regressions and Cox models.

RESULTS

Among the 49,019 participants, 95.0% reported receipt of at least one dose and 89.8% were up to date with recommendations. All 7C antecedents were significantly associated with the outcomes, although effects were weaker for up-to-date vaccination status and uptake speed. The strongest effects (most vs. least vaccine-favourable attitude level, at-least-one-dose vaccination status) were observed for collective responsibility (OR: 14.44; 95%CI: 10.72-19.45), calculation (OR: 10.29; 95%CI: 7.53-14.05), and confidence in the wider system (OR: 8.94; 95%CI: 6.51-12.27).

CONCLUSION

This study demonstrates that the 7C not only explain vaccine intention, but also vaccine behaviours, and underpins the importance of developing vaccine promotion strategies considering the 7C antecedents.

Navigating the pandemic: A critical perspective on COVID-19 responses in Central America

Following the World Health Organization’s declaration of the new coronavirus as a pandemic, nations had to act swiftly to draft effective strategies for the prevention and containment of COVID-19. International literature highlights a range of approaches taken by countries, with varying degrees of success, as measured by the quality and responsiveness of their public health systems. This brief perspective proposes a critical-gerontological reflection on the Central American countries, highlighting the divergent regional approaches to the pandemic that resulted in unequal figures between nations. Despite the intention to face the health challenge collectively, varying governmental positions had a direct impact on the health of the older population. Costa Rica and Panama responded similarly to the crisis, showcasing their better social and health scenarios compared to their peers. The Central American approach to public health was tailored to the political ideology of each country, rather than adhering to the common objectives set by the regional integration scheme in place. Despite the pandemic posing a challenge, the region remains committed to building universal, equitable, and comprehensive public health for older people.

Intention to receive the monkeypox vaccine and its psychological and sociodemographic predictors: a cross-sectional survey in the general population of Peru

OBJECTIVE

The objective of this study was to identify predictors of intention to be vaccinated against Monkeypox (Mpox) in a sample of Peruvian citizens.  METHODS: A set of sociodemographic and psychological predictors were used, such as sex, sexual orientation, educational level, previous diagnosis of COVID-19, marital status, complete vaccination against COVID-19, employment status, living with vulnerable people, presence of chronic disease, area of residence, perceived usefulness of COVID-19 vaccines, fear of Mpox, conspiracy beliefs about Mpox, among others. A total of 472 Peruvian adults participated, selected by non-probabilistic snowball convenience sampling. A sociodemographic survey, the Mpox Fear Scale, was used. Conspiracy Beliefs about Mpox was assessed using three questions created specifically for this study. For inferential purposes, simple ordinal regressions ("crude models") were performed between each factor and the outcome.  RESULTS: Regarding their intention to be vaccinated against Mpox, more than 60% expressed clear approval. Being non-heterosexual, having greater emotional fear of Mpox, and perceiving some potential for this disease to become the next pandemic were related to greater intention to vaccinate. On the other hand, being older, having low perceived usefulness of COVID-19 vaccines, and having higher conspiracy beliefs about Mpox were associated with lower intention to vaccinate.  CONCLUSION: The study provides initial information for future research seeking to better analyze Mpox vaccination intention. In addition, cross-sectional data are provided that can be used to develop public health policies that target subgroups with low prevalence of intention to vaccinate against Mpox.

Relationship Between Fear of Monkeypox and Intention to be Vaccinated Against Monkeypox in a Peruvian Sample. The Mediating Role of Conspiracy Beliefs About Monkeypox

The present study evaluated the predictive capacity of fear of Monkeypox (MPX) on the intention to be vaccinated against MPX and the influence of conspiracy beliefs as a mediating variable in this relationship in 516 Peruvian sample with an average age of 27.10 years participated. Monkeypox Fear Scale, MPX Conspiracy Beliefs Scale and a single item of intention to be vaccinated against MPX were used. Statistical analyses have included estimation of descriptive statistics for all variables in the model tested and Structural Equation Modeling to predict intention to be vaccinated against monkeypox. It has been found that fear has a positive impact on conspiracy beliefs about MPX and intention to be vaccinated against MPX. Finally, conspiracy beliefs are negatively related to intention to be vaccinated. As for indirect effects, both are statistically significant. The model explains 11.4% of the variance in beliefs and 19.1% in intention to be vaccinated. It is concluded that fear of MPX played an important role, both directly and indirectly, in the intention to be vaccinated against MPX, having conspiratorial beliefs about MPX as a mediating variable. The results have important implications for public health practices aimed at combating doubts about MPX vaccination.

Modelling the Factors That Predict the Intention to Take COVID-19 Vaccine in Nigeria

This study developed a model that predicted factors that prompt the intention to take the COVID-19 vaccine among Nigerians. Data were collected from 385 respondents across Nigeria using snowball sampling technique with online questionnaire as instrument. Results indicated that cues to action, health motivation, subjective norms, and perceived behavioural control positively predicted the intention to take COVID-19 vaccine in Nigeria. However, perceived susceptibility, severity, and COVID-19 vaccine benefits did not predict the intention to take the COVID-19 vaccine. Further findings showed that COVID-19 vaccine barrier and attitude was negatively associated with the intention to take the COVID-19 vaccine.

COVID-19 vaccination acceptance among older adults: A qualitative study in New South Wales, Australia

Objectives

The COVID-19 pandemic has had a severe impact on people across the world, particularly older adults who have a higher risk of death and health complications. We aimed to explore older adults’ intention towards COVID-19 vaccination and factors that influenced their motivation to get vaccinated.

Study design

A qualitative study was conducted in New South Wales, Australia (April 2021), involving interviews with older adults (aged 70 years and older).

Methods

In-depth interviews were carried out with 14 older adults on their perceptions around COVID-19 vaccination. The COVID-19 vaccination program had just commenced at the time of data collection. We thematically analysed interviews and organised the themes within the Behavioural and Social Drivers of Vaccination (BeSD) Framework.

Results

We found that most participants were accepting of COVID-19 vaccination. Participants’ motivation to get vaccinated was influenced by the way they thought and felt about COVID-19 disease and vaccination (including perceptions of vaccine safety, effectiveness, benefits, COVID-19 disease risk, and vaccine brand preferences) and social influences (including healthcare provider recommendation, and influential others). The uptake of COVID-19 vaccination was also mediated by practical issues such as access and affordability.

Conclusions

Efforts to increase COVID-19 vaccination acceptance in this population should focus on highlighting the benefits of vaccination. Support should be given to immunisation providers to enhance efforts to discuss and recommend vaccination to this high-risk group.

Sociodemographic Factors Associated with COVID-19 Vaccination among People in Guatemalan Municipalities

The Republic of Guatemala's reported COVID-19 vaccination coverage is among the lowest in the Americas and there are limited studies describing the disparities in vaccine uptake within the country. We performed a cross-sectional ecological analysis using multi-level modeling to identify sociodemographic characteristics that were associated with low COVID-19 vaccination coverage among Guatemalan municipalities as of 30 November 2022. Municipalities with a higher proportion of people experiencing poverty (β = -0.25, 95% CI: -0.43--0.07) had lower vaccination coverage. Municipalities with a higher proportion of people who had received at least a primary education (β = 0.74, 95% CI: 0.38-1.08), children (β = 1.07, 95% CI: 0.36-1.77), people aged 60 years and older (β = 2.94, 95% CI: 1.70-4.12), and testing for SARS-CoV-2 infection (β = 0.25, 95% CI: 0.14-0.36) had higher vaccination coverage. In the simplified multivariable model, these factors explained 59.4% of the variation in COVID-19 vaccination coverage. Poverty remained significantly associated with low COVID-19 vaccination coverage in two subanalyses restricting the data to the time period of the highest national COVID-19-related death rate and to COVID-19 vaccination coverage only among those aged 60 years or older. Poverty is a key factor associated with low COVID-19 vaccination and focusing public health interventions in municipalities most affected by poverty may help address COVID-19 vaccination and health disparities in Guatemala.

For COVID-19, what are the priorities of normalized prevention and control strategies?

The COVID-19 pandemic has ravaged the world for three years. Most countries have adjusted policies and strategies in response to the burden of COVID-19. The severity of COVID-19 seems to be diminishing as the case fatality rate has declined and the number of vaccinated people has increased markedly. Given the large population worldwide, we need to pay attention to the continuing COVID-19 burden. Globally, the number of cases remains at a certain level, and the number of cases is still increasing in China. We also need to deal with shortages of medical resources, antipyretics, and home nursing facilities. SARS-CoV-2 will coexist with humans for a long time, and predicting viral mutations and pandemic trends will be difficult. The reform of the whole public health system is imperative. A comprehensive surveillance system should be created to determine the proportion of various pathogens and to guard against mixed infections of respiratory infectious diseases. A comprehensive response mechanism, including preventive measures and medical treatments, should be created as soon as possible to monitor the status of the epidemic and to deal with the long-term health burden of SARS-CoV-2.

Effect of religious fatalism and concern about new variants on the acceptance of COVID-19 vaccines

Introduction

To protect public health, it is important that the population be vaccinated against COVID-19; however, certain factors can affect vaccine acceptance.

Objective

The objective of this study was to determine whether religious fatalism and concern about new variants have a significant effect on the acceptance of COVID-19 vaccines.

Methodology

An explanatory study was conducted with 403 adults of legal age captured through non-probabilistic convenience sampling in vaccination centers in the 13 health networks of the Regional Health Directorate of Puno, Peru. Data were collected through a brief scale of religious fatalism, a scale of acceptance of vaccines against COVID-19 and a scale of concern about a new variant of COVID-19.

Results

The proposed model obtained an adequate fit. There was a negative effect of religious fatalism on vaccine acceptance, a positive effect of fatalism on vaccine rejection, a positive effect of concern about new variants on the acceptance of vaccines, and a positive effect of concern about new variants on vaccine rejection.

Conclusion

These findings provide evidence for the usefulness of considering both religious fatalism and concern about new variants affect the intention to receive the COVID-19 vaccine in adults in southern Peru.

Relationship between the fear of COVID-19 and social isolation and depression in elderly individuals

BACKGROUND

The COVID-19 pandemic has seriously affected elderly individuals and it has been associated with high morbidity and mortality rates. This study was conducted to examine the relationship between fear of COVID-19, social isolation and depression in elderly individuals.

METHODS

The study is a descriptive type. The sample consisted of 362 elderly people. The study data were collected using the Introductory Information Form, the Fear of COVID-19 Scale, the Nottingham Health Profile Social Isolation Scale and the Geriatric Depression Scale-Short Form.

RESULTS

It was determined there was a positive and moderate relationship between fear of COVID-19 and depression and social isolation, and a positive and high relationship between social isolation and depression, and the results were statistically significant (P < 0.001).

CONCLUSIONS

Public health nurses, during epidemic periods, should help elderly individuals manage their fears about the disease. In addition, they should lead the practices that can sustain social participation and prevent depression in the elderly.

Identifying Drivers of COVID-19 Vaccine Uptake among Residents of Yopougon Est, Abidjan, Côte d'Ivoire

This study applied the Fogg Behavioral Model (FBM) to identify and prioritize factors influencing COVID-19 vaccination among residents of Yopougon Est, Abidjan, Côte d'Ivoire. A total of 568 respondents were recruited from among individuals entering eleven participant recruitment and data collection sites located near high pedestrian trafficked areas. Among all respondents, 52% reported being vaccinated versus 48% who reported not being vaccinated. Of those who reported being vaccinated, 42% reported received a single dose, 54% a double dose, and 4% three or more doses. A categorical regression analysis suggested that potential predictors of COVID-19 vaccination included acceptance and rejection factors, which are both aligned with motivation in the FBM and socio-demographic characteristics, proximity to services, and religion. Our findings suggest that demand creation activities should target individuals with less formal education, those who are not formally employed, non-Catholic Christians, and individuals who do not identify as Akan. Results also suggest the need to design programmatic messages and activities that focus on generating family and community support for COVID-19 vaccination.

Facilitating free and paid vaccine acceptance in Malaysia: effectiveness of vaccine and fear of COVID-19

Purpose

This study aims to examine how demographic and psychological predictors of free and paid vaccine acceptance operate within an infectious environment. The psychological predictors were derived from the protection motivation theory (PMT), including the appraised effectiveness of vaccine in containing the pandemic and the fear of COVID-19.

Design/methodology/approach

A representative data set that consists of responses from 2,850 Malaysians was used in this study. Multi-level modelling was used to analyse the data.

Findings

Results indicated that the acceptance of free and paid vaccination did not differ by region. This suggests that the effects of the included psychological predictors on vaccine acceptance are independent from the environment. Malaysians are more likely to endorse both free and paid vaccination when it is perceived as effective in controlling the pandemic. When the vaccine is deemed as an effective preventive of COVID-19, Malaysians tend to seek free vaccination. Although fear of COVID-19 did significantly predict the endorsement of vaccination, it is a weaker predictor than the perceived effectiveness of vaccine.

Originality/value

This research used a large representative data set and the PMT framework in addressing vaccine acceptance in Malaysia.

Prevalence and Predictors of Intention to be Vaccinated Against COVID-19 in Thirteen Latin American and Caribbean Countries

The presence of a significant number of people who do not intend to be vaccinated could negatively impact efforts to control the COVID-19 pandemic. Therefore, this study sought to determine the prevalence of intention to be vaccinated against COVID-19 and associated sociodemographic and psychosocial factors in thirteen countries in Latin America and the Caribbean (LAC). A total of 5510 people from 13 LAC countries participated. Frequencies, percentages, bivariate analyses using chi-square tests, and Poisson regression analysis with robust variance were used. The countries with the highest prevalence of intention to be vaccinated were Brazil (96.94%), Cuba (89.59%), Chile (84.59%), and Mexico (78.33%). On the other hand, the countries with the lowest prevalence were El Salvador (54.01%), Paraguay (55.87%), and Uruguay (56.40%). Prevalence is also reported according to some sociodemographic and health variables. It was found that country, male sex, hours exposed to information about COVID-19, university education, living in an urban area, belief in the animal origin of the virus, perceived likelihood of contracting COVID-19, perceived severity of COVID-19, and concern about infecting others significantly predicted intention to be vaccinated in the 13 LAC countries. While most countries had a high prevalence of intention to be vaccinated, there are still subgroups that have levels of intention that may be insufficient to predict the presence of community immunity. In this sense, knowing the estimates of vaccination intention rates, as well as the associated sociodemographic and psychological factors, can be used to plan actions and interventions that will inform about the safety and benefits of vaccines, as well as strengthen trust in health authorities.

Predictors of Intention to Vaccinate Against COVID-19 in a Peruvian Sample

BACKGROUND

Vaccination against COVID-19 is considered one of the most effective strategies to control this global public health crisis. However, vaccine hesitancy is one of the main threats to mitigating the pandemic. The present study aimed to identify predictors of intention to vaccinate against COVID-19 in 3 geographical regions of Peru.

METHODS

An online analytical cross-sectional study was conducted. Participants were selected by non-probability convenience sampling and size was estimated using the online statistical calculator proposed by Soper. A total of 529 Peruvian nationals completed the questionnaires. Student's t-test and Fisher's F test (ANOVA) were used. A significance level of .05 was considered.

RESULTS

Face-to-face work (β = 2.037, P < .001), fear of COVID-19 (β = .461, P < .001), vaccine confidence (β = 2.881, P < .001) and trust in health care institutions (β = .432, P < .01) predict a higher intention to receive the vaccine. However, the variables perception of a worldwide conspiracy (β = -1.900, P < .001), and practice Protestant religion (β = -2.274, P < .001) predict negatively their acceptance.

CONCLUSION

Several positive predictors of intention to vaccinate against COVID-19 have been identified. However, having a perception of a global conspiracy and practice Protestant religion are shown to be risk variables for vaccine acceptance. Therefore, there is a need to develop strategies to ensure high uptake and success of COVID-19 vaccination campaigns.

Sociodemographic Predictors Associated with the Willingness to Get Vaccinated against COVID-19 in Peru: A Cross-Sectional Survey

During the race for the development of a vaccine against COVID-19, even before its commercialization, part of the population has already shown a growing fear of its application. We designed an analytical cross-sectional study using an anonymous survey in the 25 departments of Peru. We surveyed whether the participants were planning on getting vaccinated, as well as other characteristics that were cross-checked in a uni-, bi- and multivariate manner. Of the 1776 respondents, 70% (1251) stated that they were planning to be vaccinated, 20% (346) did not know yet or doubted it, and 10% (179) did not want to be vaccinated. We observed that those who did not get infected with COVID-19 exhibited a higher frequency to not wanting or were uncertain about getting vaccinated (aPR: 1.40; 95% CI: 1.09-1.81; p-value = 0.008). In contrast, there was a lower frequency of vaccine refusal among university students (aPR: 0.75; 95% CI: 0.61-0.92; p-value = 0.005) and healthcare workers (aPR: 0.59; 95% CI: 0.44-0.80; p-value = 0.001); adjusted by place of residence. There is still an important percentage of respondents who do not want to be vaccinated or are hesitant to do it, which was associated with educational level, being a healthcare worker and if they were previously infected with COVID-19. Our results could offer useful information about COVID-19 vaccination campaigns.

Attitudes of Healthcare Professionals and General Population Toward Vaccines and the Intention to Be Vaccinated Against COVID-19 in Spain

Background: To achieve herd immunity, the acceptance of the COVID-19 vaccine by the population, especially healthcare professionals, plays a key role. The objective of the present paper is to address the differences in attitudes among Spanish healthcare professionals compared with the general population regarding COVID-19 vaccination. Methods: This cross-sectional study included data from 2,136 adults (n = 664 healthcare professionals) from an online survey conducted from May 6 to June 9, 2021. The Vaccination attitudes examination scale was used to measure the negative attitudes toward vaccines. Four subscales: mistrust of vaccine benefit, worries about the unforeseen future effect, concerns about commercial profiteering, and preference for natural immunity were calculated. Generalized linear mixed models were conducted to study these associations. Results: Between 10.2 and 22.6% of the subjects showed high levels of negative attitudes toward vaccines. However, only 1.5% of our sample (2.1% among healthcare professionals) refused to get the COVID-19 vaccine when it was offered because they chose otherwise. Retired people showed the lowest concerns and the highest trust in vaccines. No statistically significant effects were found between working in a healthcare field and having higher positive attitudes toward vaccines. Conclusion: Low levels of rejection against the COVID-19 vaccine were identified in the present sample. However, despite being at a higher risk, health care professionals did not show higher positive attitudes toward vaccines. Furthermore, refusal percentage to vaccination was higher among healthcare professionals compared with non-healthcare professionals. Developing a strategy to increase positive attitudes against the COVID-19 vaccine should be an objective for public health policy.
