Vaccines A Graphic History by Paige V. Polinsky

几个世纪以来,疫苗一直被用来将人们的身体安全地引入疾病,它们每年都会拯救数百万人的生命。通过给人们提供一种弱化或死亡的疾病版本,疫苗可以让身体产生抗体,以便日后识别和对抗这种疾病。

Vaccines have been used to safely introduce people’s bodies to diseases for centuries, and they save millions of lives each year. By giving people a weakened or dead version of a disease, a vaccine allows the body to develop antibodies which recognize and fight the disease later on.
