Impact of IP Exemptions for COVID-19 Vaccines on Vaccinated Populations in Less Developed Countries

Abstract

Since the outbreak of the COVID-19 in 2020, global economic growth and public health have been greatly impacted. On the one hand, the epidemic has disrupted global supply chains, affecting the economic stability of various countries, and increased the vulnerability of the global economy. On the other hand, the epidemic has exposed the rapid spread of epidemic diseases around the world by globalization, which has become a systemic risk.As one of the best solutions to prevent the spread of large-scale diseases in the greatest public range in the history of human medical development, vaccines have become the key to whether humans can defeat the COVID-19 as soon as possible. This paper shows the changes in the vaccinated population of less developed countries after the implementation of the COVID-19 vaccine exemption by establishing a mathematical model, and proposes that less developed countries should adjust their policies to help the vaccine exemption to vaccinate more people in their own countries according to existing international rules.
