Shen Qianshu looked at the information and only felt a cold shiver run down her back. A thin layer of cold sweat covered her entire body, and there was something in her mind prickling her, making it was extremely painful.
It was simply too ridiculous.
Ye Ling actually never had a vaccination.
Nowadays, when a child was born, almost all vaccines that could be given within the age of three would have been given. The child mortality rate was high in ancient times, mostly due to smallpox and plague. At that time, there was no vaccination, so the children were weak. If they caught smallpox or the plague, there were few that could survive.
Now, medical knowledge was very developed, and children were vaccinated as soon as they are born. It was very rare for people to catch influenza, unless it was a mutant virus such as SARS. Even the doctors would never have expected Ye Ling to catch influenza.
Furthermore, it was an older body that had caught it.
