Penicilin was soon used for serious diaseases such as neumonia and tuberculosis, which caused many deaths. Fleming Florey, and Chain received the Nobel Prize in 1945. Antibiotics were a great discovery in medicine, allowing people to survive something that would have killed them before]]> 2023-05-11 14:41:04 UTC https://padlet.com/mp929488/lf3nnbx0vxs4r1rr/wish/2587324502
