Elsevier established a free COVID-19 resource centre in January 2020, offering information in English and Mandarin. The centre grants permission for free access to its research in PubMed Central and other repositories. A review paper titled "Vaccine hesitancy in the era of COVID-19" examines factors influencing vaccine acceptance during the pandemic. The study analyzed 15 articles published between 2020 and 2021, revealing that vaccine acceptance for COVID-19 was lower than for influenza, with acceptance rates ranging from 54.3% to 86.1%. Factors influencing acceptance included ethnicity, working status, religiosity, politics, gender, education, and income. Common reasons for vaccine refusal included general opposition to vaccines, safety concerns, belief in the vaccine's uselessness, lack of trust, and doubts about its effectiveness. The review highlights the importance of addressing vaccine hesitancy to ensure high vaccination rates and prevent disease outbreaks. The study also notes that vaccine hesitancy is influenced by political ideology, with Democratic partisanship associated with higher acceptance. Healthcare workers showed varied acceptance rates, with some studies showing no difference between healthcare and non-healthcare personnel. The review emphasizes the need for targeted interventions to improve vaccine confidence and address underlying concerns.Elsevier established a free COVID-19 resource centre in January 2020, offering information in English and Mandarin.
