The two doctors sent by Zhao Yao have arrived in the capital. After resting for two days, they entered the palace to teach the Imperial Physicians about cowpox vaccination.
The Imperial Physicians humbly learned from the two doctors and cooperated earnestly with them, making the cowpox vaccination process go very smoothly.
The first batch of children to receive the cowpox vaccination were originally the children of the Imperial Physicians themselves. However, the Emperor later realized that his grandsons and granddaughters were of suitable age for the vaccination, so he had his sons and daughters bring their children to the palace for the vaccination.
