Abstract
BACKGROUND Understanding of the behavioural and social drivers (BeSD) of vaccination is key to addressing vaccine hesitancy and accessibility issues. Vietnam's national COVID-19 vaccination programme resulted in high uptake of primary doses among adults, but lower booster doses for adults and primary doses for 5-11 years. This scoping review assessed BeSD influencing COVID-19 vaccine uptake in Vietnam to design interventions on reaching the national vaccination targets. METHOD We conducted a scoping review by searching PubMed, MedRxiv, LitCOVID, COVID-19 LOVE platform, WHO's COVID-19 research database and seven dominant Vietnamese language medical journals published in English or Vietnamese between 28 December 2019 and 28 November 2022. Data were narratively synthesised and summarised according to the four components of the WHO BeSD framework. The drivers were then mapped along the timeline of COVID-19 vaccine deployment and the evolution of the pandemic in Vietnam. RESULTS We identified 680 records, of which 39 met the inclusion criteria comprising 224 204 participants. Adults' intention to receive COVID-19 vaccines for themselves (23 studies) ranged from 58.0% to 98.1%. Parental intention to vaccinate their under 11-year-old children (six studies) ranged from 32.8% to 79.6%. Key drivers of vaccination uptake were perceived susceptibility and severity of disease, perceived vaccine benefits and safety, healthcare worker recommendation, and positive societal perception. Commonly reported COVID-19 vaccines' information sources (six studies) were social and mainstream media (82%-67%), television (72.7%-51.6%) and healthcare workers (47.5%-17.5%). Key drivers of COVID-19 uptake remained consistent for both adults and children despite changes in community transmission and vaccine deployment. CONCLUSION Key enablers of vaccine uptake for adults and children included perceived disease severity, perceived vaccine benefits and safety and healthcare worker recommendations. Future studies should assess vaccine communication targeted to these drivers, national policies and political determinants to optimise vaccine uptake.

Quantifying the heterogeneous impact of lockdown policies on different socioeconomic classes during the first COVID-19 wave in Colombia. Sci Rep 2023; 13:16481. [PMID: 37777581 PMCID: PMC10542364 DOI: 10.1038/s41598-023-43685-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 09/27/2023] [Indexed: 10/02/2023] Open
Abstract
In the absence of vaccines, the most widespread reaction to curb the COVID-19 pandemic worldwide was the implementation of lockdowns or stay-at-home policies. Despite the reported usefulness of such policies, their efficiency was highly constrained by socioeconomic factors determining their feasibility and their associated outcome in terms of mobility reduction and the subsequent limitation of social activity. Here we investigate the impact of lockdown policies on the mobility patterns of different socioeconomic classes in the three major cities of Colombia during the first wave of the COVID-19 pandemic. In global terms, we find a consistent positive correlation between the reduction in mobility levels and the socioeconomic stratum of the population in the three cities, implying that those with lower incomes were less capable of adopting the aforementioned policies. Our analysis also suggests a strong restructuring of the mobility network of lowest socioeconomic strata during COVID-19 lockdown, increasing their endogenous mixing while hampering their connections with wealthiest areas due to a sharp reduction in long-distance trips.

Abstract
OBJECTIVES The literature on vaccine hesitancy has widely commented on the various factors leading some to feel particularly at risk of disease infection while others do not. But little attention has been paid to whether we also see such differences regarding people's assessment of their personal vulnerability towards vaccine adverse events (AEs). METHODS We designed two cross-sectional online surveys among representative samples of the French mainland population (n = 2015 and 3087). We asked participants if they felt, more than others, at risk of severe vaccine related side effects and to explain why. We performed two separate mixed effect binomial regressions models: 1) to explore the link between the feeling of being particularly at risk of severe vaccine related AEs and socio-demographic characteristics, source of information, trust in health agencies and partisan orientation; 2) to explore the link between the fear of side effects and vaccine hesitancy. RESULTS We found that 15% of respondents felt to be, more than others, at risk of severe vaccine-related adverse events and that this feeling was associated to negative attitudes to vaccines. This feeling was particularly prevalent among women, those with a lower income, lower educational attainment and lower trust in public health institutions. The vast majority of the reasons given by responders are unrelated to genuine risk factors of vaccine related adverse events. CONCLUSIONS These findings suggest that vaccine hesitancy is at least partly grounded in a feeling of vulnerability towards vaccine adverse events.

Hum Vaccin Immunother 2023; 19:2245720. [PMID: 37594508 PMCID: PMC10443971 DOI: 10.1080/21645515.2023.2245720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 07/21/2023] [Accepted: 08/04/2023] [Indexed: 08/19/2023] Open
Abstract
Despite widespread availability of vaccines against SARS-CoV-2 virus, the cause of Coronavirus Disease 2019 (COVID-19), its uptake in many Arab countries is relatively low. This literature review aimed to scope evidence on COVID-19 vaccine hesitancy (VH) in the Arab world. A total of 134 articles reporting prevalence of COVID-19 VH and associated factors, conducted in any of the 22 Arab League countries, were reviewed. COVID-19 VH prevalence ranged from 5.4% to 83.0%. Female gender, young age, low education level and lack of previous influenza vaccine uptake were most commonly reported to be associated with COVID-19 VH. The most-reported personal concerns contributing toward VH were related to the rapid development, safety and side effects of vaccine, as well as an overall lack of trust in government policies toward pandemic control and widespread conspiracy theories. Tailored interventions to enable the distribution of trusted information and enhance public acceptance of immunization are warranted.

Konstantinus A, Konstantinus I. Choice preference and willingness to pay for COVID-19 vaccination in Namibia. Vaccine X 2023; 14:100324. [PMID: 37333055 PMCID: PMC10249368 DOI: 10.1016/j.jvacx.2023.100324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 03/12/2023] [Accepted: 05/30/2023] [Indexed: 06/20/2023] Open
Abstract
Background Namibia has not been spared from the coronavirus (COVID-19) pandemic, and as intervention the Namibian government has rolled out vaccination programmes. This study was conducted before the roll out of these vaccines to assess the preference for COVID-19 vaccinations. Stated preference studies provide information about social demand, access, willingness-to-pay and financing for future COVID-19 vaccination. Methods A stated choice experiment (SCE) survey was administered to a sample of 506 participants from Namibia's general population between October 2020 and December 2020. Participants were asked to make a series of hypothetical choices and estimate their preference for different attributes of a vaccine. A latent class model was used to analyse the SCE data. The study also assessed anti-vaccination behaviour, past vaccination behaviour, impacts of COVID-19 on mental and physical health and Willingness-To-Pay (WTP) measures. The WTP measures were captured as out-of-pocket and further calculated using the marginal rate of substitution method in SCE. Results Data from 269 participants was included in the analysis. Vaccine side effects (40.065), population coverage (4.688), payment fee to receive vaccine immediately (3.733) were the top three influential attributes for vaccine preferences. Accordingly, increases in mild and severe side effects of vaccine options had negative impacts on utility; with an average WTP of N$728.26 to reduce serious side effects. The average WTP to receive a high-quality vaccine with 90% efficient was found to be N$233.11 (US$15.14). Across classes, there was a strong preference for vaccines with high effectiveness over longer durations of time. Conclusions The results provide useful information for the Namibian government to improve the current strategies for vaccine rollout interventions.

Abstract
Background and Aims Despite evidence that COVID-19 vaccination can strengthen mental health, there is limited evidence about this in Bangladesh. Thus, this comparative study assessed the prevalence and factors associated with mental health problems between vaccine receivers and nonreceivers. Methods Using a snowball sampling technique, a web-based cross-sectional study was conducted among a total of 459 participants. The survey questionnaire included sociodemographic information, the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder (GAD-7), and the Trauma Screening Questionnaire (TSQ-10). Results The study found that mental health problems were nonsignificantly prevalent in the vaccine nonreceivers than those who received it (i.e., 24.79% vs. 20.60% for depression, 21.20% vs. 16.60% for anxiety, and 15.30% vs. 12.60% for posttraumatic stress disorder). Female gender, chronic condition, smoking status, and alcohol consumption were the risk factors for mental health problems. Conclusion This study's findings suggest that the COVID-19 vaccination necessarily improves mental health outcomes. However, the study had limitations in terms of its design and sampling technique, and further research is needed to establish a cause-effect relationship between vaccination and mental health problems.

Abstract
Vaccination rates are still insufficient to prevent the spread of COVID-19, so immunity must be increased among the population in order to reduce the virus' spread and the associated medical and psychosocial effects. Although previous work has identified various factors associated with a low willingness to get vaccinated, the role of emotions such as fear of vaccination (FVAC) or fear of COVID-19 (FCOV), vaccination as a subjective norm (SN), psychological factors like general control beliefs (CB) or psychological resilience, and their interaction have been investigated less intensively. We used data from three cross-sectional waves of the German Panel COSMO (November 2021, N = 1010; February 2022, N = 1026; March 2022, N = 1031) and multiple logistic regression analyses to test whether vaccination rates are moderated by those factors. After controlling for covariates (age, sex, confidence in own intuition, optimism, well-being), we found that CB was no significant predictor of vaccination status. Higher FCOV and higher ratings in SN, however, were associated with an increased likelihood of being vaccinated. In contrast, higher FVAC was associated with a decreased likelihood of being vaccinated. Psychological resilience did not consistently moderate the associations between fear and vaccination status.
