To counter the imbalance in vaccine distribution during the COVID-19 pandemic, Albertsen and more recently Germaniet alhave suggested a new system of taxation coined as ‘VaxTax’ that would force higher-income countries to fund the access of low-income and middle-income countries (LMICs) to new vaccines in times of pandemic. I will argue that this idea faces numerous challenges of ethical, sociopolitical and economical nature that may hinder any effort to solve the numerous health challenges that LMICs face. I argue that while (...) it is an interesting idea, it is neither sufficient nor will it ever be easily implemented because of socioeconomic or practical reasons. (shrink)
