Project description:BackgroundMultiple COVID-19 vaccines have been approved for use in adolescents; these vaccines play a critical role in limiting the transmission and impact of COVID-19. This systematic review aims to summarize the willingness of adolescents aged 10 to 19 years to receive the COVID-19 vaccination and the factors influencing their decision.MethodsA search of literature published between January 2018 and August 2022 was performed in Medline©, EMBASE©. and CINAHL© electronic databases. Studies published in English that assessed adolescents' intentions to receive the COVID-19 vaccine were included. Qualitative studies and those unrelated to the COVID-19 vaccine were excluded. The study was conducted based on the PRISMA guidelines.ResultsOf the 1074 articles retrieved, 13 were included in the final review. Most studies were conducted in the US (n = 3) and China (n = 3). The pooled prevalence of COVID-19 vaccine acceptance among adolescents was 63% (95% CI: 52-73%). Factors influencing intent to vaccinate were divided into five categories: "Socio-demographic determinants"; "Communication about COVID-19 pandemic and vaccination"; "COVID-19 vaccine and related issues"; "COVID-19 infection and related issues" and "Other determinants". The enablers were sociodemographic factors including older age, higher education level, good health perception, and parental norms in terms of parental vaccination acceptance; perceived vaccine effectiveness and safety; a desire to protect themselves and others; recent vaccination; and anxiety. The barriers were concerns over vaccine effectiveness, safety, and long-term side effects; low perceived necessity and risk of infection; and needle phobia.ConclusionsThis review highlighted that adolescents' intent to vaccinate is driven by a desire to protect themselves and others. However, concerns over vaccine effectiveness, safety, and long-term side effects hinder COVID-19 vaccine uptake. To improve vaccination acceptance, policymakers should address adolescents' concerns via more targeted public health messaging, while schools should leverage peer norms to positively influence vaccination intent.

Project description:ObjectiveTo examine SARS-CoV-2 vaccine confidence, attitudes and intentions in Australian adults as part of the iCARE Study.Design and settingCross-sectional online survey conducted when free COVID-19 vaccinations first became available in Australia in February 2021.ParticipantsTotal of 1166 Australians from general population aged 18-90 years (mean 52, SD of 19).Main outcome measuresPrimary outcome: responses to question 'If a vaccine for COVID-19 were available today, what is the likelihood that you would get vaccinated?'.Secondary outcome: analyses of putative drivers of uptake, including vaccine confidence, socioeconomic status and sources of trust, derived from multiple survey questions.ResultsSeventy-eight per cent reported being likely to receive a SARS-CoV-2 vaccine. Higher SARS-CoV-2 vaccine intentions were associated with: increasing age (OR: 2.01 (95% CI 1.77 to 2.77)), being male (1.37 (95% CI 1.08 to 1.72)), residing in least disadvantaged area quintile (2.27 (95% CI 1.53 to 3.37)) and a self-perceived high risk of getting COVID-19 (1.52 (95% CI 1.08 to 2.14)). However, 72% did not believe they were at a high risk of getting COVID-19. Findings regarding vaccines in general were similar except there were no sex differences. For both the SARS-CoV-2 vaccine and vaccines in general, there were no differences in intentions to vaccinate as a function of education level, perceived income level and rurality. Knowing that the vaccine is safe and effective and that getting vaccinated will protect others, trusting the company that made it and vaccination recommended by a doctor were reported to influence a large proportion of the study cohort to uptake the SARS-CoV-2 vaccine. Seventy-eight per cent reported the intent to continue engaging in virus-protecting behaviours (mask wearing, social distancing, etc) postvaccine.ConclusionsMost Australians are likely to receive a SARS-CoV-2 vaccine. Key influencing factors identified (eg, knowing vaccine is safe and effective, and doctor's recommendation to get vaccinated) can inform public health messaging to enhance vaccination rates.

Project description:BackgroundPublic polling indicates that vaccine uptake will be suboptimal when COVID-19 vaccines become available. Formative research seeking an understanding of weak vaccination intentions is urgently needed.MethodsNationwide online survey of 804 U.S. English-speaking adults. Compensated participants were recruited from the U.S. through an internet survey panel of 2.5 million residents developed by a commercial survey firm. Recruitment was based on quota sampling to produce a U.S. Census-matched sample representative of the nation with regard to region of residence, sex, and age.ResultsCOVID-19 vaccination intentions were weak, with 14.8% of respondents being unlikely to get vaccinated and another 23.0% unsure. Intent to vaccinate was highest for men, older people, individuals who identified as white and non-Hispanic, the affluent and college-educated, Democrats, those who were married or partnered, people with pre-existing medical conditions, and those vaccinated against influenza during the 2019-2020 flu season. In a multiple linear regression, significant predictors of vaccination intent were general vaccine knowledge (β = 0.311, p < .001), rejection of vaccine conspiracies (β = -0.117, p = .003), perceived severity of COVID-19 (β = 0.273, p < .001), influenza vaccine uptake (β = 0.178, p < .001), having ≥ 5 pre-existing conditions (β = 0.098, p = .003), being male (β = 0.119, p < .001), household income of ≥ $120,000 (β = 0.110, p = .004), identifying as a Democrat (β = 0.075, p < .029), and not relying upon social media for virus information (β = -0.090, p 〈002). Intent to vaccinate was lower for Fox News (57.3%) than CNN/MSNBC viewers (76.4%) (χ2(1) = 12.68, p < .001). Political party differences in threat appraisals and vaccine conspiracy beliefs are described.ConclusionsDemographic characteristics, vaccine knowledge, perceived vulnerability to COVID-19, risk factors for COVID-19, and politics likely contribute to vaccination hesitancy.

Project description:BackgroundNegative attitudes towards vaccines and an uncertainty or unwillingness to receive vaccinations are major barriers to managing the COVID-19 pandemic in the long-term. We estimate predictors of four domains of negative attitudes towards vaccines and identify groups most at risk of uncertainty and unwillingness to receive a COVID-19 vaccine in a large sample of UK adults.MethodsData were cross-sectional and from 32,361 adults in the UCL COVID-19 Social Study. Ordinary least squares regression analyses examined the impact of socio-demographic and COVID-19 related factors on four types of negative vaccine attitudes: mistrust of vaccine benefit, worries about unforeseen effects, concerns about commercial profiteering, and preference for natural immunity. Multinomial regression examined the impact of socio-demographic and COVID-19 related factors, negative vaccine attitudes, and prior vaccine behaviour on uncertainty and unwillingness to be vaccinated for COVID-19.Findings16% of respondents displayed high levels of mistrust about vaccines across one or more domains. Distrustful attitudes towards vaccination were higher amongst individuals from ethnic minority backgrounds, with lower levels of education, lower annual income, poor knowledge of COVID-19, and poor compliance with government COVID-19 guidelines. Overall, 14% of respondents reported unwillingness to receive a vaccine for COVID-19, whilst 23% were unsure. The largest predictors of both COVID-19 vaccine uncertainty and refusal were low-income groups (< £16,000, a year), having not received a flu vaccine last year, poor adherence to COVID-19 government guidelines, female gender, and living with children. Amongst vaccine attitudes, intermediate to high levels of mistrust of vaccine benefit and concerns about future unforeseen side effects were the most important determinants of both uncertainty and unwillingness to vaccinate against COVID-19.InterpretationNegative attitudes towards vaccines are a major public health concern in the UK. General mistrust in vaccines and concerns about future side effects in particular will be barriers to achieving population immunity to COVID-19 through vaccination. Public health messaging should be tailored to address these concerns and specifically to women, ethnic minorities, and people with lower levels of education and incomes.FundingThe Nuffield Foundation [WEL/FR-000022583], the MARCH Mental Health Network funded by the Cross-Disciplinary Mental Health Network Plus initiative supported by UK Research and Innovation [ES/S002588/1], and the Wellcome Trust [221400/Z/20/Z and 205407/Z/16/Z].

Project description:BackgroundCoronavirus disease 2019 (COVID-19) vaccination is necessary to reach herd immunity and essential for mitigating the spread of the pandemic. In May 2021, the US FDA and the EU have expanded the emergency use authorization for a COVID-19 vaccine to children aged 12 to 15. The aim of this study was to investigate parental acceptability of COVID-19 vaccination for their children, factors affecting their acceptability, and children's perceptions of COVID-19 vaccines in Republic of Korea.MethodsWe conducted a questionnaire survey at two tertiary hospitals from May 25, 2021 to June 3, 2021. Subjects were parents having children under 18 years and children aged 10-18 years.ResultsTwo hundred twenty-six parents and 117 children aged 10-18 years were included in the final analysis. Overall, 76.5% and 64.2% of parents intended to get vaccinated against COVID-19 and intended to have their children vaccinated, respectively. However, only 49.6% of children responded that they would get COVID-19 vaccination. In the multivariate analysis, high confidence in the safety of COVID-19 vaccines (adjusted odds ratio [AOR], 4.87; 95% confidence interval [CI], 1.32-24.12), parents' willingness to vaccinate themselves (AOR, 19.42; 95% CI, 6.85-64.00), and awareness of the need to vaccinate children against COVID-19 (AOR, 13.15; 95% CI, 4.77-41.27) were associated with positive factors intention to vaccinate their children.ConclusionThis study provides insight into how parents think about the COVID-19 vaccine for their children in South Korea. Our findings could be referenced in establishing a policy for childhood COVID-19 vaccination in the future.

Project description:BackgroundThe success of vaccination efforts to curb the COVID-19 pandemic will require broad public uptake of immunization and highlights the importance of understanding factors associated with willingness to receive a vaccine.MethodsU.S. adults aged 65 and older enrolled in the HeartlineTM clinical study were invited to complete a COVID-19 vaccine assessment through the HeartlineTM mobile application between November 6-20, 2020. Factors associated with willingness to receive a COVID-19 vaccine were evaluated using an ordered logistic regression as well as a Random Forest classification algorithm.ResultsAmong 9,106 study participants, 81.3% (n = 7402) responded and had available demographic data. The majority (91.3%) reported a willingness to be vaccinated. Factors most strongly associated with vaccine willingness were beliefs about the safety and efficacy of COVID-19 vaccines and vaccines in general. Women and Black or African American respondents reported lower willingness to vaccinate. Among those less willing to get vaccinated, 66.2% said that they would talk with their health provider before making a decision. During the study, positive results from the first COVID-19 vaccine outcome study were released; vaccine willingness increased after this report.ConclusionsEven among older adults at high-risk for COVID-19 complications who are participating in a longitudinal clinical study, 1 in 11 reported lack of willingness to receive COVID-19 vaccine in November 2020. Variability in vaccine willingness by gender, race, education, and income suggests the potential for uneven vaccine uptake. Education by health providers directed toward assuaging concerns about vaccine safety and efficacy can help improve vaccine acceptance among those less willing.Trial registrationClinicaltrials.gov NCT04276441.

Project description:ObjectivesThe resurgence in cases and deaths due to COVID-19 in many countries suggests complacency in adhering to COVID-19 preventive guidelines. Vaccination, therefore, remains a key intervention in mitigating the impact of the COVID-19 pandemic. This study investigated the level of adherence to COVID-19 preventive measures and intention to receive the COVID-19 vaccine among Ugandans.Design, setting and participantsA nationwide cross-sectional survey of 1053 Ugandan adults was conducted in March 2021 using telephone interviews.Main outcome measuresParticipants reported on adherence to COVID-19 preventive measures and intention to be vaccinated with COVID-19 vaccines.ResultsOverall, 10.2% of the respondents adhered to the COVID-19 preventive guidelines and 57.8% stated definite intention to receive a SARS-CoV-2 vaccine. Compared with women, men were less likely to adhere to COVID-19 guidelines (Odds Ratio (OR)=0.64, 95% CI 0.41 to 0.99). Participants from the northern (4.0%, OR=0.28, 95% CI 0.12 to 0.92), western (5.1%, OR=0.30, 95% CI 0.14 to 0.65) and eastern regions (6.5%, OR=0.47, 95% CI 0.24 to 0.92), respectively, had lower odds of adhering to the COVID-19 guidelines than those from the central region (14.7%). A higher monthly income of ≥US$137 (OR=2.31, 95% CI 1.14 to 4.58) and a history of chronic disease (OR=1.81, 95% CI 1.14 to 2.86) were predictors of adherence. Concerns about the chances of getting COVID-19 in the future (Prevalence Ratio (PR)=1.26, 95% CI 1.06 to 1.48) and fear of severe COVID-19 infection (PR=1.20, 95% CI 1.04 to 1.38) were the strongest predictors for a definite intention, while concerns for side effects were negatively associated with vaccination intent (PR=0.75, 95% CI 0.68 to 0.83).ConclusionBehaviour change programmes need to be strengthened to promote adherence to COVID-19 preventive guidelines as vaccination is rolled out as another preventive measure. Dissemination of accurate, safe and efficacious information about the vaccines is necessary to enhance vaccine uptake.

Project description:BackgroundDespite the success of childhood immunization in reducing vaccine-preventable diseases, vaccine hesitancy is now a global health threat to this achievement. The current COVID-19 pandemic may change the picture of vaccine hesitancy toward childhood immunizations, which could influence the mothers' intention to vaccinate their children against COVID-19.AimTo measure the prevalence and related factors of vaccine hesitancy towards childhood immunization during the era of COVID-19 along with the prevalence of mothers' intention to vaccinate their children the future COVID-19 and its association with childhood vaccine hesitancy.MethodsCross sectional study was conducted among 270 Saudi mothers attending outpatient clinics at King Abdullah University Hospital (KAAUH) in Riyadh by purposive sampling technique. Data were collected from January to February 2021 using SAGE Group standardized questionnaire.ResultsAlthough most mothers strongly agree on the importance of the vaccine (79%), almost one-fourth of mothers were hesitant towards childhood immunization (24.31%). Similar percentage of mothers' intended to vaccinate their children against COVID-19 in the next 6 months was reported (24%). Vaccine hesitancy was found to be a significant predictor of mothers' intention. Mothers' education level was significantly associated with being hesitant towards childhood immunization as well as the intention to accept the future COVID-19 vaccine (p < 0.05). Main reason that was highly significantly associated with being hesitant is the concerns about the side effect (50%).ConclusionThe present study reported a considerable percentage of mothers who are hesitant towards childhood immunization which predicts their intension to vaccinate towards COVID19 and is associated with the level of education.
