The COVID-19 Resource Centre, established by Elsevier in January 2020, provides free information in English and Mandarin on the novel coronavirus. The centre is hosted on Elsevier Connect and grants permission for all COVID-19-related research to be made available in PubMed Central and other public repositories, with unrestricted reuse and analysis rights, provided that the original source is acknowledged. G. Troiano and A. Nardi conducted a narrative review to analyze vaccine hesitancy during the COVID-19 pandemic, focusing on the acceptance of the COVID-19 vaccine. They searched PubMed (MEDLINE) for original peer-reviewed articles published during the pandemic, using the search terms "Vaccine hesitancy AND COVID-19." Fifteen studies were included, with vaccine acceptance percentages ranging from 86.1% among students to 77.6% among the general population. Factors influencing acceptance or refusal included ethnicity, working status, religiosity, politics, gender, age, education, income, and concerns about safety and efficacy. The most common reasons for refusing the vaccine included general mistrust, doubts about the vaccine's effectiveness, and belief in the vaccine's ineffectiveness due to the harmless nature of COVID-19. The review highlights the need for further efforts to address vaccine hesitancy and provide accurate information to the public.The COVID-19 Resource Centre, established by Elsevier in January 2020, provides free information in English and Mandarin on the novel coronavirus.
