This week, the Royal Swedish Academy of Sciences announced the names of Nobel laureates in different fields. This year, the Nobel Prize in Biomedical Sciences was awarded to Swedish geneticist Svante Paabo for his discoveries concerning the DNA sequence of apes and human evolution. His work is especially meaningful as the question of human origin has long been a major concern to mankind. Modern-day wise humans belong to the genus Homo sapiens, along with seven ancient human races that existed millions (...) of years ago. Over time, many species became extinct and Professor Paabo discovered the gene transfer of these extinct species to Homo sapiens. With this discovery, he laid the foundation for other scientists to continue to search for the origin of modern humans. (shrink)

To achieve herd immunity against Covid-19, the willingness of residents to get vaccinated and successful vaccination policies go hand in hand. This paper aims to understand the perceptions, acceptance, hesitation, and refusal of Covid-19 vaccines in Nghe An, Vietnam. We used an online survey to collect data during March of 2021. The Bayesian regression model (BRM) was used to identify the factors affecting vaccination decisions. The empirical results show that respondents’ livelihoods were considerably affected by the Covid-19 pandemic, and there (...) was a subtle difference in Covid-19 impacts on the lives of urban residents and their rural counterparts. In addition, respondents reported an overall positive attitude towards Covid-19 vaccination in which 84.28% were willing to get vaccinated, 14.85% were hesitant, and 0.87% refused vaccination. Their vaccination decisions were associated with vaccine side effects, information, income, job type, gender, and trust in government. Our findings offer policy implications for devising strategies for vaccine distribution in the study area and beyond. (shrink)
