“…Chen et al indicated that the practice of prevention behavior among the elderly in China was positively correlated with the scores of knowledge related to COVID-19 [ 23 ]. At different stages of this pandemic, knowledge about COVID-19 and vaccines have contributed to the vaccination willingness of older populations in China, Brazil, Malaysia, Singapore, Colombia, and other countries [ 40 , 41 , 42 , 43 , 44 ]. Therefore, it is of practical significance to improve the understanding of the elderly on their own susceptibility, effectiveness, and safety of vaccines through various publicity and education ways (such as social media, offline lectures, etc.)…”

Background: Given the prevalence of the omicron variant and decreased immunity provided by vaccines, it is imperative to enhance resistance to COVID-19 in the old population. We planned to explore the hesitancy rate toward the booster dose of the COVID-19 vaccine and the association between risk perception and the abovementioned rate among people aged 60 and older. Methods: This national cross-sectional study was conducted in mainland China from 25 May to 8 June 2022, targeting people who were 60 years old or above. Four dimensions were extracted from the Health Belief Model (HBM) to assess participants’ perceived risk levels, including perceived susceptibility, perceived severity, perceived barriers, and perceived benefit. An independent Chi-square test was used to compare the vaccine hesitancy rates among different groups stratified by characteristics. Univariable and multivariable logistic regression models were performed to explore the associations between risk perception and hesitancy rate. Results: Of 3321 participants, 17.2% (95% CI: 15.9–18.5%) were hesitant about booster shots of COVID-19 vaccines. Believing that they were ineligible for vaccination due to certain illnesses (38.3%), concern about vaccine safety (32.0%), believing the booster shots were unnecessary (33.1%), and their limitation on movements (28.0%) were the main reasons for vaccine hesitation. Adjusted by all the selected covariates, people with low perception level of susceptibility (aOR = 1.39, 95% CI: 1.00–1.92) and benefit (low: aOR = 3.31, 95% CI: 2.01–5.45; moderate: aOR = 2.23, 95% CI: 1.75–2.85) were less likely to receiving the booster dose, and the same results were found in people with higher perceived barriers (moderate: aOR = 2.67, 95% CI: 2.13–3.35; high: aOR = 2.04, 95% CI: 1.14–3.67). Our estimates were stable in all four models. Conclusions: In total, 17.2% of the people aged 60 years and older in China were hesitant about booster dose of COVID-19 vaccines, and it was closely associated with a lower level of perceived susceptibility and benefit, as well as a higher level of perceived barriers. Concerns about contraindications, vaccine safety, and limited movements were the main reasons for vaccine hesitancy. Targeted public health measure is a priority to improve the understanding of the elderly on their own susceptibility and vulnerability and clear the obstacles to vaccination.

“…Another study performed in approx. 6900 Singaporean residents aged 56–75 years, found that trusted sources of information play a large role in vaccine acceptance, and that respondents who placed greater levels of trust in formal sources of information (government sources and local news on television and radio) were significantly more likely to be vaccinated than those who relied on social media [ 44 ].…”

Understanding motivations and concerns surrounding COVID-19 vaccine uptake is important to reduce vaccine hesitancy and inform strategies to mitigate concerns and increase vaccine uptake. This study aimed to explore motivations and concerns associated with COVID-19 vaccination among adults seeking their first COVID-19 vaccine in a regional Australian community with low prevalence of COVID-19, who received a medical consult prior to vaccination. Medical records from consults were audited and the modified Framework Method was used to conduct qualitative content analysis of data, generating themes and overall core concepts related to motivations for COVID-19 vaccination and associated concerns. There were 102 people included in the study, 81% of whom were aged ≥60 years. Concerns surrounding COVID-19 vaccination included five core concepts: 1. Perceived vaccine risks, 2. Perceived vaccine performance, 3. Uncertainty, 4. Autonomy, and 5. Fairness in access; and a further five core concepts were generated from motivations to seek vaccination: 1. Protection, 2. Occupational or facility responsibility or requirement, 3. Trust in primary healthcare physician, 4. Autonomy, and 5. Civic duty. These motivating factors and concerns can be used to inform strategies and education to increase vaccine uptake in ongoing and future vaccine rollouts.

“…There is contradicting evidence regarding the association between age and vaccine hesitancy. In Singapore, middle-aged and older adults were more hesitant to receive a COVID-19 vaccine [ 24 ], whereas a study conducted in Ireland and the United Kingdom [ 25 ] reported that younger (18–24 years) people are more hesitant.…”

Vaccination Intention against COVID-19 among the Unvaccinated in Jordan during the Early Phase of the Vaccination Drive: A Cross-Sectional Survey

et al. 2022

Objective: This study assessed the intention and predictors of accepting the corona virus disease 2019 (COVID-19) vaccine in Jordan. Method: A national-level online survey was conducted among adults (≥18 years) in Jordan between June and September 2021. Descriptive analyses were performed to report vaccination intent. In addition, bivariate and multivariate logistic regression analyses were done to evaluate the association between vaccination intent and its predictors. Results: A total of 2307 adults participated. Most of them (83.7%) expressed an intention to receive a COVID-19 vaccine. Their vaccination intention was significantly (p < 0.001) associated with male gender (aOR: 2.6), residence in the Amman region (aOR: 51.8), and no history of COVID-19 infection (aOR: 6.0). In contrast, individuals aged 50-64 years (aOR: 0.2, p < 0.001), Jordanians (aOR: 0.7, p = 0.038), and those with an occupation designated as “other” (unemployed, general workers, housewives) (aOR: 0.2, p < 0.001) were less likely to have a positive vaccination intent. Among the health belief model constructs, perceived future (aOR: 2.8) and present (aOR: 5.0) susceptibility to COVID-19 infection; severity of complications (aOR: 9.9); and benefits (aOR: 100.8) were significantly (p < 0.001) associated with a higher likelihood of having a vaccination intent. On the other hand, individuals who are concerned about the efficacy (aOR: 0.2) and side effects (aOR: 0.2) of the vaccine were less likely to have a positive vaccination intent (p < 0.001). Conclusion: Despite having high rates of intention to receive a COVID-19 vaccine, Jordanians, older adults and housewives, general workers and unemployed individuals were less likely to be vaccinated. These findings highlight that need-based public health campaigns are necessary to ensure maximum COVID-19 vaccination uptake in Jordan.
