In late 2019, the coronavirus disease (Covid-19) was first discovered in China and quickly spread to Asian countries. The attitude of health care professionals toward vaccination is an indicator of public concern, although the epidemic varies from country to country. In response to the pandemic, our associations organized research meetings and conducted a cross-sectional study. A questionnaire1 for the vaccines used in the research was developed by Prof. Hao-Yun Kao and Prof. Yen-Chiao Lu, and the COVID-19 Vaccine Attitude Scale of °zgüden et al. (2022) was used as the other questionnaire. The research was conducted between October 2021 and December 2022 in Taiwan, Turkey, Myanmar, Mongolia and Thailand. The results found that Taiwanese healthcare workers have a more positive perception compared to the survey results from other countries. In addition, surveys conducted in Mongolia and Thailand showed positive attitudes, subjective norms, perceived behavioral control, intentions, behavior and anxiety responses based on the lowest impact of social media on healthcare professionals' professional knowledge across all dimensions. Living in the Covid-19 has become a new normal. In this article, we report on the attitudes of health workers in Taiwan, Turkey, Myanmar, Mongolia and Thailand to provide information for interventions aimed at increasing awareness of potential obstacles to the adoption of the Covid-19 vaccine.
