“…These findings might reflect the fact that individuals’ previous positive experiences with influenza vaccines may have resulted in them having more reassuring attitudes towards COVID vaccination. To support this, findings from previous [ 28 , 29 ] and current pandemics [ 43 , 44 , 45 , 46 , 47 , 48 ] showed that regular influenza vaccine takers reported increased risk perception regarding H1N1 influenza, as well as positive attitudes in regard to vaccine safety and the value of vaccination in general.…”

Global Trends and Correlates of COVID-19 Vaccination Hesitancy: Findings from the iCARE Study

et al. 2021

The success of large-scale COVID-19 vaccination campaigns is contingent upon people being willing to receive the vaccine. Our study explored COVID-19 vaccine hesitancy and its correlates in eight different countries around the globe. We analyzed convenience sample data collected between March 2020 and January 2021 as part of the iCARE cross-sectional study. Univariate and multivariate statistical analyses were conducted to explore the correlates of vaccine hesitancy. We included 32,028 participants from eight countries, and observed that 27% of the participants exhibited vaccine hesitancy, with increases over time. France reported the highest level of hesitancy (47.3%) and Brazil reported the lowest (9.6%). Women, younger individuals (≤29 years), people living in rural areas, and those with a lower perceived income were more likely to be hesitant. People who previously received an influenza vaccine were 70% less likely to report COVID-19 vaccine hesitancy. We observed that people reporting greater COVID-19 health concerns were less likely to be hesitant, whereas people with higher personal financial concerns were more likely to be hesitant. Our findings indicate that there is substantial vaccine hesitancy in several countries, with cross-national differences in the magnitude and direction of the trend. Vaccination communication initiatives should target hesitant individuals (women, younger adults, people with lower incomes and those living in rural areas), and should highlight the immediate health, social and economic benefits of vaccination across these settings. Country-level analyses are warranted to understand the complex psychological, socio-environmental, and cultural factors associated with vaccine hesitancy.

“…During the first state of emergency, the present research was done when no vaccine was available and little was known about the SARS-COV-2 virus, while the IPSOS survey was conducted in 2021 after the vaccine started to be available for older adults. Attitudes toward vaccination can change throughout a public health crisis ( Fridman et al, 2021 ). Most likely, subsequent scientific information about vaccination benefits and the pro-vaccination national campaign have encouraged vaccination behavior in people with chronic illness.…”

COVID-19 Pandemic Worry and Vaccination Intention: The Mediating Role of the Health Belief Model Components

et al. 2021

Given the negative consequences of the ongoing COVID-19 pandemic on public health, his study aimed at investigating: (1) the differences between adults with and without chronic illness in buying behavior, vaccination intention, pandemic worry, and the health belief model (HBM) components; (2) the HBM components as mediators of the relationship between pandemic worry and vaccination intention. The sample consisted of 864 adults (66.6% females, Mage = 47.61, SD = 9.23), of which 20.5% reported having a chronic illness. Associations between pandemic worry, vaccination intention, and HBM were ascertained using correlation and mediation analyses. Individuals with chronic illness reported a higher level of pandemic worry, higher levels of perceived threat, greater benefits from vaccination, had lower self-efficacy and bought more medicine and sanitary/hygienic products. No significant differences were observed regarding vaccination intention, barriers against vaccination, and changes in food buying behavior. We found that the relationship between pandemic worry and vaccination intention was partially mediated by the perceived threat of disease and the benefits of vaccination. Pandemic worry predicted vaccination intention directly but also through the contribution of the perceived threat of disease and the benefits of vaccination. These findings suggest that presenting evidence of COVID-19 vaccine efficacy and the benefits of having the vaccine (especially for vulnerable groups, such as chronic illness patients) will encourage the population to follow vaccination recommendations.

“…After more than a year into the COVID-19 pandemic, it is clear that age is the most important risk factor for becoming severely ill from the coronavirus. A recent study by Fridman et al (2021) found that individuals with less favorable attitudes toward a COVID-19 vaccination also perceived the virus to be less threatening. As young adults are generally not at risk of becoming severely ill or dying from the virus, they may be less motivated to take the vaccine.…”

Do Social Norms Influence Young People’s Willingness to Take the COVID-19 Vaccine?

Although young adults are not at great risk of becoming severely ill with COVID-19, their willingness to get vaccinated affects the whole community. Vaccine hesitancy has increased during recent years, and more research is needed on its situational determinants. This paper reports a preregistered experiment (N = 654) that examined whether communicating descriptive social norms -information about what most people do -is an effective way of influencing young people's intentions and reducing their hesitancy to take the COVID-19 vaccine. We found weak support for our main hypothesis that conveying strong (compared to weak) norms leads to reduced hesitancy and stronger intentions. Furthermore, norms did not produce significantly different effects compared to standard vaccine information from the authorities. Moreover, no support was found for the hypothesis that young people are more strongly influenced by norms when the norm reference group consists of other young individuals rather than people in general. These findings suggest that the practical usefulness of signaling descriptive norms is rather limited, and may not be more effective than standard appeals in the quest of encouraging young adults to trust and accept a new vaccine.
