Project description:Controversy around the safety and efficacy of COVID-19 vaccines may lead to low vaccination rates. Survey data were collected in April and August 2020 from a total of 2343 Australian adults. A quarter (n = 575, 24%) completed both surveys. A generalized linear mixed model analysis was conducted to determine whether willingness to vaccinate changed in the repeated sample, and a multinominal logistic regression was conducted in all participants to determine whether willingness to vaccinate was associated with demographics, chronic disease, or media use. Willingness to vaccinate slightly decreased between April (87%) and August (85%) but this was not significant. Willingness to vaccinate was lower in people with a certificate or diploma (79%) compared to those with a Bachelor degree (87%), p < 0.01 and lower in infrequent users of traditional media (78%) compared to frequent users of traditional media (89%), p < 0.001. Women were more likely to be unsure if they would be willing to vaccinate (10%) compared to men (7%), p < 0.01. There were no associations between willingness to vaccinate and age, chronic disease, or social media use. Promotion of a COVID-19 vaccine should consider targeting women, and people with a certificate or diploma, via non-traditional media channels.

Project description:The uptake of the COVID-19 vaccine will determine the trajectory for improved population health and economic recovery from the COVID-19 pandemic. Identifying factors associated with vaccine acceptance is imperative as public health officials strategize to improve uptake. In this study, we identified predictors of vaccine willingness and acceptance using univariate logistic regression to model predictors and calculate odds ratios. Participants (N = 946) who reported greater vaccine willingness were male, older, and had a higher level of education and income. Behaviors indicative of reducing the spread of COVID-19 (e.g., testing) and perceived risk of COVID-19 infection were associated with vaccine willingness, as were participants who believed they were "highly likely" to be infected (by a factor of 8). Education tailored to demographic groups with low vaccine uptake should focus on the high degree of communicability associated with COVID-19. Implementing mobile healthcare screenings could remove barriers to healthcare, thereby improving health equity.

Project description:IntroductionTo evaluate Chinese parents' willingness to vaccinate their children against COVID-19, identify its predictors, and provide a reference for raising the COVID-19 vaccination rate for children.MethodPubMed, Cochrane Library, Embase, and the databases in Chinese, including CNKI, WanFang, VIP, CBM, were searched from December 2019 to June 2022, and citation tracking was used to identify relevant studies. To calculate the rate with 95% confidence intervals (CI), a random-effects model was used. To explore sources of heterogeneity, sensitivity analysis and subgroup analysis were conducted. This analysis was registered on PROSPERO (CRD42022346866) and reported in compliance with the PRISMA guidelines.ResultOverall, 80 studies were screened, and 13 studies with 47994 parents were included after removing duplicates and excluding 19 studies that did not meet the selection criteria by title, abstract and full-text screening. The pooled willingness rate of Chinese parents to vaccinate their children against COVID-19 was 70.0% (95% CI: 62.0~78.0%). Level of education, perceived susceptibility of children infected with COVID-19, and parental attitudes toward vaccination (such as perceived efficacy and safety of the COVID-19 vaccines, parental willingness to vaccinate themselves, parental vaccination hesitancy, and the history of children's vaccination against influenza) were the main predictors of parents' intention to vaccinate their children.DiscussionChinese parents' willingness to vaccinate their children against COVID-19 is moderate, and factors including parental education level, perceived susceptibility of children infected with COVID-19, and parental attitudes toward vaccination affect this decision. Fully identifying these factors and their mechanism will be essential to further raise the willingness rate.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier: CRD42022346866.

Project description:ObjectiveTo investigate Chinese guardians' willingness to vaccinate teenagers (WVT) against COVID-19, we conducted a national wide survey in 31 provinces in mainland China.MethodsWe involved 16133 guardians from 31 provinces in Chinese Mainland from August 6th to 9th, 2021. The question "Are you willing to vaccinate teenagers of COVID-19 vaccine?" was designed to capture WVT. Odds ratios (OR) with 95% Confidence Intervals (CI) for potential factors of WVT were estimated using multiple logistic regression models.ResultsIn total, 13327 (82.61%) of the respondents expressed positive WVT, 12.90% of the respondents were uncertain but inclined to vaccinate their teenagers. Meanwhile, 3.89% of the respondents were uncertain and inclined to reject, and 0.60% of the respondents rejected the vaccines. After adjusting for potential confounders, the married, total family income last year, reject to Categoly1 vaccines, access information about the COVID-19 vaccines from community workers, low COVID-19 vaccine conspiracy, guardian's vaccination behavior, and the importance of vaccinating teenagers were all independent factors that affected the guardians' likely to accept. Further, the current study found that lower trust in doctors and vaccine developers was associated with negative WVT. The reasons for negative WVT included teenagers' young age and guardians' worries on the safety and effectiveness of COVID-19 vaccines.ConclusionThis large-scale study assessed Chinese guardians' WVT against COVID-19, as well as its potential influencing factors, which is useful for international and national decision-makers.

Project description:Introduction Vaccines against coronavirus disease (COVID-19) have been developed in unprecedented time. However, the effectiveness of any vaccine is dictated by the proportion of the population willing to be vaccinated. This observational population-based study examines intentions to be vaccinated against COVID-19 throughout the pandemic. Methods In November 2020, longitudinal data from a nationally representative sample of 7,547 U.S. adults enrolled in the Understanding America Study were analyzed using multinomial logistic regression. Participants reporting being willing, undecided, and unwilling to get vaccinated against COVID-19 across 13 assessments conducted from April to October 2020. Public attitudes to vaccination against COVID-19 were also assessed on a 4-point Likert scale. Results Willingness to vaccinate declined from 71% in April to 53.6% in October. This was explained by an increase in the percentage of participants undecided about vaccinating (from 10.5% to 14.4%) and the portion of the sample unwilling to vaccinate (from 18.5% to 32%). The population subgroups most likely to be undecided/unwilling to vaccinate were those without a degree (undecided: RRR=2.47, 95% CI=2.04, 3.00; unwilling: RRR=1.92, 95% CI=1.67, 2.20), Black participants (undecided: RRR=2.18, 95% CI=1.73, 2.74; unwilling: RRR=1.98, 95% CI=1.63, 2.42), and female participants (undecided: RRR=1.41, 95% CI=1.20, 1.65; unwilling: RRR=1.29, 95% CI=1.14, 1.46). Participants who were older or were on higher incomes were least likely to be undecided or unwilling to vaccinate. Concerns about potential side effects of a vaccine were common. Conclusions Intentions to be vaccinated against COVID-19 have declined rapidly during the pandemic and close to half of Americans are undecided or unwilling to be vaccinated.

Project description:COVID-19 vaccination for children is crucial to achieve herd immunity. This is the first systematic review and meta-analysis to estimate parents' and guardians' willingness to vaccinate their children against COVID-19 and identify the determinants of vaccination intention. Systematic research was performed on the two databases (PubMed and EMBASE) from inception to 6 November 2021. Acceptance rates were pooled by use of a random-effects model and all predictors of vaccine acceptance were identified according to the health belief model (HBM) framework. This analysis was registered with PROSPERO (CRD42021292326) and reported in compliance with the PRISMA guidelines. Of 452 identified records, 29 eligible studies were included (N = 68,327 participants). The estimated worldwide vaccination acceptance rate was 61.40% (95% CI: 53.56-68.69%, I2 = 99.3%), ranging from 21.6% to 91.4% across countries and regions. In the determinant assessment, the age of parents and guardians, access to scientific information and recommendations, routine and influenza vaccination behavior, and the willingness of parents and guardians to vaccinate themselves were potentially significant predictors of the vaccination willingness. Given the limited quality and quantity of included articles, future studies with a rigorous design will be necessary for the confirmation of our findings.

Project description:BackgroundChildren age 5-11 became eligible for COVID-19 vaccination in November 2021 in the United States, but vaccine uptake in this age group remains low. Understanding reasons why parents are hesitant to vaccinate their children may provide critical insights to help protect children from COVID-19 infection. This study examines factors associated with parents' willingness to vaccinate their children.MethodsWe conducted a cross-sectional survey focusing on the Los Angeles County adult residents between March and June 2021. Our analytic sample focused on a subgroup of participants who self-report having a child. Predictors included parents' vaccination status and beliefs about COVID-19. We used multivariable logistic regression analysis and calculated the predicted probabilities of parents' willingness to vaccinate their children.ResultsParents (n = 401) who worried about catching the virus, had trust in vaccine development and the COVID-19 vaccine approval process, and vaccinated against COVID-19 were more likely to be willing to vaccinate their children. Socio-economic, racial and ethnic differences were no longer statistically significant in the adjusted model. Predicted probabilities of parents who were willing to vaccine their children were 55% among the vaccinated and 36% among the unvaccinated.ConclusionsParents' intent to vaccinate their children is influenced by their perceived severity of the pandemic, trust in the vaccine development process, and their vaccination status, which can be the potential drivers of hesitancy to vaccinate their children.

Project description:This study aims to evaluate acceptance of COVID-19 vaccines and the impact of risk perception on vaccine acceptance and personal health protective behaviors in Taiwan. A nationwide cross-sectional study was conducted from 19 to 30 October 2020; 1020 participants were included in the final analysis; chi-square and logistic regression analyses were conducted. In total, 52.7% of participants were willing to receive COVID-19 vaccines, 63.5% perceived the severity of COVID-19 in Taiwan as "not serious", and nearly 40% were worried about COVID-19 infection. Participants with higher perceived severity of COVID-19 had significantly higher odds of refusing the vaccine (OR = 1.546), while those worried about infection had lower odds of poor health protective behaviors (OR = 0.685). Vaccine refusal reasons included "the EUA process is not strict enough" (48.7%) and "side effects" (30.3%). Those who had previously refused other vaccinations were 2.44 times more likely to refuse the COVID-19 vaccines. Participants' age had an influence on COVID-19 vaccine acceptance. In general, the Taiwanese public's acceptance of the vaccine was lower than that in other high-income countries. Elderly participants and those with college-level education and above who had previously refused vaccines had lower willingness to receive a COVID-19 vaccine. Risk perception was positively associated with personal health protective behaviors but negatively associated with COVID-19 vaccine acceptance.

Project description:We aimed to assess the factors associated with a lack of willingness to vaccinate against COVID-19 among adults in Poland three months after the introduction of mass vaccination against COVID-19 in Poland. This cross-sectional study was carried out between 8 and 18 April 2021 on a representative nationwide sample of 1131 inhabitants of Poland aged 18 and over. Almost one-third of adult inhabitants of Poland (30%; 95%CI: 27.4-32.7%) declared a lack of willingness to vaccinate against COVID-19. Females had higher odds of refusing COVID-19 vaccination compared with males (OR = 1.68; 95%CI: 1.25-2.27). The lack of higher education was significantly (p < 0.001) associated with greater odds of refusing the COVID-19 vaccination. Participants living in rural areas compared with those living in the largest cities (over 500,000 inhabitants) had three times higher odds of refusing the COVID-19 vaccination (OR = 3.20; 95%CI: 1.71-6.01). Respondents who declared willingness to vote for one of the right-wing political parties publicly supporting the anti-vaccination movement in Poland had eight times higher odds (OR = 8.01; 95%CI: 3.65-17.60) of refusing the COVID-19 vaccination compared with other groups. Moreover, those who had three children or more, respondents who declared passivity towards participating in religious practices as well as active internet users had significantly higher odds of refusing the COVID-19 vaccination.
