截至2021年8月，COVID-19仍在日本蔓延。疫苗接种是控制COVID-19的关键措施之一，于2021年2月开始。之前的研究报告称，COVID-19疫苗接种可以减少感染人数和死亡率。然而，对感染传播的模拟表明，在日本接种疫苗是不够的。因此，我们建立了易感-感染-恢复-接种-接种-死亡模型来验证第一次和第二次接种剂量对减少日本感染个体数量的影响；这包括一个感染模拟。结果证实，适当的疫苗接种措施将充分减少感染人数，降低死亡率。
As of August 2021, COVID-19 is still spreading in Japan. Vaccination, one of the key measures to bring COVID-19 under control, began in February 2021. Previous studies have reported that COVID-19 vaccination reduces the number of infections and mortality rates. However, simulations of spreading infection have suggested that vaccination in Japan is insufficient. Therefore, we developed a susceptible-infected-recovered-vaccination1-vaccination2-death model to verify the effect of the first and second vaccination doses on reducing the number of infected individuals in Japan; this includes an infection simulation. The results confirm that appropriate vaccination measures will sufficiently reduce the number of infected individuals and reduce the mortality rate.
