Frontiers in Public Health, Journal Year: 2022, Volume and Issue: 10

Published: Dec. 15, 2022

Background The reluctance of individuals to obtain solid vaccine-induced immunity represents a fundamental challenge containing the spread SARS-CoV-2, including its highly mutated variants. We aimed assess vaccination acceptance and associated factors for COVID-19 vaccine booster dose among elderly people (≥60 years old) in China, providing theoretical practical reference universal policy. Methods A national anonymous survey was conducted mainland China from May 25 June 8, 2022, using stratified random sampling method. Individuals 60 age above were target population. chi-squared test Cochran-Armitage trend used compare examine rates by characteristics. Via backward stepwise method, multivariable logistic regression models established with acceptance. Two-sided P < 0.05 considered statistically significant. Results Of 3,321 eligible participants, 82.8% (95% CI: 81.5–84.1%) willing receive shots. Concerns about contraindications (38.3%), safety (32.0%), limited movement (28.0%) main reasons hesitancy. Nearly one-third still believed that unnecessary after receiving initial vaccination. Older adults low level perceived barriers (aOR = 1.86, 95% CI, 1.03–3.38), high benefit 2.31, 1.38–3.87), higher cues action (moderate, aOR 2.22, 1.39–3.56; high, 5.46, 3.44–8.67) more likely accept dose. Other major affecting rate occupation, time spent on social media, history, knowledge score vaccines. In addition, those over 70 age, rising awareness susceptibility could be better gateway improving their willingness get vaccinated. Conclusions total recruited older Acceptance behaviors closely related factors, perception barriers, benefit, as well cues. Targeted public health measures are priority coverage valid population, not only prevent infection poor prognosis caused emerging variants but also reduce huge disease economic burden long-term sequelae SARS-CoV-2 infection.

Why Some People Are Hesitant to Receive COVID-19 Boosters: A Systematic Review

Tropical Medicine and Infectious Disease, Journal Year: 2023, Volume and Issue: 8(3), P. 159 - 159

Published: March 5, 2023

As the COVID-19 pandemic continues and transitions to an endemic stage, booster vaccines will play important role in personal public health. However, convincing people take boosters be a key obstacle. This study systematically analyzed research that examined predictors of vaccine hesitancy. A search PubMed, Medline, CINAHL, Web Science, Scopus uncovered 42 eligible studies. Globally, average vaccination hesitancy rate was 30.72%. Thirteen factors influencing emerged from literature: demographics (gender, age, education, income, occupation, employment status, ethnicity, marital status), geographical influences (country, region, residency), adverse events, perceived benefit/efficacy, susceptibility, severity, prior history infection, recommendations, health knowledge information, skepticism/distrust/conspiracy theories, type. Vaccine communication campaigns interventions for COVID should focus on confidence, complacency, convenience.

A Systematic Review on Sociodemographic, Financial and Psychological Factors Associated with COVID-19 Vaccine Booster Hesitancy among Adult Population

Vaccines, Journal Year: 2023, Volume and Issue: 11(3), P. 623 - 623

Published: March 9, 2023

While considerable evidence supports the safety and efficacy of COVID-19 vaccines, a sizable population expresses vaccine hesitancy. As per World Health Organization, hesitancy is one top 10 hazards to global health. Vaccine varies across countries, with India reporting least was higher toward booster doses than previous shots. Therefore, identifying factors determining hesitance (VBH) sine qua non successful vaccination campaign.This systematic review followed Preferred Reporting Items for Systematic Reviews Meta-analysis (PRISMA) 2020 standards. A total 982 articles were pooled from Scopus, PubMed Embase, while 42 that addressed VBH finally included further analysis.We identified responsible divided them into three major groups: sociodemographic, financial, psychological. Hence, 17 stated age be factor hesitancy, most reports suggesting negative correlation between fear poor outcomes. Nine studies found females expressing greater males.

Coronavirus disease 2019 (COVID-19) has wreaked havoc across the globe for approximately three years. Vaccination is a key factor to ending this pandemic, but its protective effect diminishes over time. A second booster dose at right time needed. To explore willingness receive fourth of COVID-19 vaccine and influencing factors, we commenced national, cross-sectional anonymous survey in mainland China among people aged 18 above from October 24 November 7, 2022. total 3,224 respondents were eventually included.

Confidence current domestic situation effectiveness previous vaccinations, uncertainty about extra protection main reasons hesitancy. Perceived benefit (aOR = 1.29, 95% 1.159–1.40) cues action 1.73, 1.60–1.88) positively associated with acceptance, whereas perceived barriers 0.78, 0.72–0.84) self-efficacy 0.79, 0.71–0.89) both negatively it. Additionally, sex, age, vaccination history, social media, satisfaction government's response also factors affecting intention. Factors intention similar results.
