On November 21st (Thursday), I had the opportunity to speak about "Japan's Vaccination Schedule and Safe Vaccination" in the "Vaccination" course of the Master's program in Medical Science at Mie University Graduate School. This year, for the first time in Japan, a comprehensive course on vaccinations was established at Mie University Graduate School. I would like to express my sincere gratitude to Professor Motoya Kamiya for providing me with this valuable opportunity.
