Common mistakes
- Viruses are not cells and are not killed by antibiotics. “Malaria is a virus” is a 0.
- Antibodies are not antibiotics. One is made by you; the other is a medicine for bacteria.
- Vaccines do not contain a full live measles infection in the MMR sense students fear — Combined: inactive/dead/weakened or antigens. They do not treat an infection you already have the way antibiotics treat bacteria.
- “The bacteria become immune” is sloppy. People become immune; bacteria become resistant.
