The COVID-19 pandemic continues to impact daily life, including health system operations, despite the availability of vaccines that are effective in greatly reducing risks death and severe disease. Misperceptions vaccine safety, efficacy, risks, mistrust institutions responsible for vaccination campaigns have been reported as factors contributing hesitancy. This study investigated hesitancy globally June 2021. Nationally representative samples 1,000 individuals from 23 countries were surveyed. Data analyzed descriptively, weighted multivariable logistic regressions used explore associations with Here, we show more than three-fourths (75.2%) 23,000 respondents report acceptance, up 71.5% one year earlier. Across all countries, is associated a lack trust safety science, skepticism about its efficacy. Vaccine hesitant also highly resistant required proof vaccination; 31.7%, 20%, 15%, 14.8% approve requiring it access international travel, indoor activities, employment, public schools, respectively. For ongoing succeed improving coverage going forward, substantial challenges remain be overcome. These include increasing among those reporting lower confidence addition expanding low- middle-income countries.

The current crisis created by the coronavirus pandemic is impacting all facets of life. Coronavirus vaccines have been developed to prevent infection and fight pandemic. Since might be only way stop spread coronavirus. World Health Organization (WHO) has already approved several vaccines, many countries started vaccinating people. Misperceptions about persist despite evidence vaccine safety efficacy.To explore scientific literature find determinants for worldwide COVID-19 hesitancy as reported in literature.PRISMA Extension Scoping Reviews (PRISMA-ScR) guidelines were followed conduct a scoping review on willingness vaccinate. Several databases (e.g., MEDLINE, EMBASE, Google Scholar) searched relevant articles. Intervention- (i.e., vaccine) outcome- hesitancy) related terms used search these databases. was conducted 22 February 2021. Both forward backward reference lists checked further studies. Three reviewers worked independently select articles extract data from selected literature.

Widespread vaccination against COVID-19 is critical for controlling the pandemic. Despite development of safe and efficacious vaccinations, low-and lower-middle income countries (LMICs) continue to encounter barriers care owing inequitable access vaccine apprehension. This study aimed summarize available data on acceptance rates factors associated with in LMICs. A comprehensive search was performed PubMed, Scopus, Web Science from inception through August 2021. Quality assessments included studies were carried out using eight-item Joanna Briggs Institute Critical Appraisal tool cross-sectional studies. We a meta-analysis estimate pooled 95% confidence intervals (CI). total 36 met inclusion criteria review. 83,867 respondents 33 studied.

Vaccine hesitancy is a challenge for the success and optimal implementation of COVID-19 immunization programs in US. The objective this study was to summarize multilevel determinants vaccination intention US inform future intervention opportunities. To end, we conducted rapid systematic review by searching published articles via PubMed October 5, 2021, following PRISMA guidelines. One hundred six were included. According nationally representative studies, overall acceptance rate ranges from 53.6% 84.4%. Individual (demographics, health history, behaviors beliefs), interpersonal (having close friend/family member impacted COVID-19), healthcare societal level factors (healthcare provider recommendations, source/credential related information, conspiracy theories) all contributed vaccine This demonstrates that vaccines influenced various factors, particularly role providers enhancing public intent vaccination. Potential interventions mitigate people's concerns over address vaccine-related conspiracy/misinformation social media are also critical encourage uptake

Misinformation and disinformation around vaccines has grown in recent years, exacerbated during the Covid-19 pandemic. Effective strategies for countering vaccine misinformation are crucial tackling hesitancy. We conducted a systematic review to identify describe communications-based used prevent ameliorate effect of mis- dis-information on people's attitudes behaviours surrounding vaccination (objective 1) examined their effectiveness 2). searched CINAHL, Web Science, Scopus, MEDLINE, Embase, PsycInfo MedRxiv March 2021. The search strategy was built three themes(1) communications media; (2) misinformation; (3) vaccines. For trials addressing objective 2, risk bias assessed using Cochrane randomized tool (RoB2). Of 2000 identified records, 34 eligible studies addressed 1, 29 which also 2 (25 RCTs 4 before-and-after studies). Nine 'intervention approaches' were identified; most focused content intervention or message (debunking/correctional, informational, use disease images other 'scare tactics', humour, intensity, inclusion warnings, communicating weight evidence), while two delivery (timing source). Some strategies, such as scare tactics, appear be ineffective may increase endorsement. Communicating with certainty, rather than acknowledging uncertainty efficacy risks, found backfire. Promising approaches include weight-of-evidence scientific consensus related myths, humour incorporating warnings about encountering misinformation. Trying debunk misinformation, informational approaches, had mixed results. This identifies some promising communication Interventions should further evaluated by measuring effects uptake, distal outcomes knowledge attitudes, quasi-experimental real-life contexts.
