Your Immune System When you are infected by a microbe, it takes time for your body to make enough white blood cells with the correct antibody.

Signs your Immune system is working: Coughing Sneezing Fever Sore throat

Once the microbe is killed off, your antibodies decrease Your Immune System Once the microbe is killed off, your antibodies decrease

After a second infection by the same microbe, your body makes the correct antibodies much faster

Antibiotics Antibiotics are medicines proscribed by doctors when harmful microbes have made you ill

Antibiotics – how do they really work? Some antibiotics stop bacteria from reproducing – they do this by interfering with DNA replication, protein synthesis, etc.

Antibiotics – how do they really work? Other antibiotics kill bacteria – they do this by destroying their cell wall

Antibiotics ONLY work against bacteria https://www.youtube.com/watch?v=znnp-Ivj2ek

Vaccines contain a dead or weak form of the disease- causing microbe

Vaccines White blood cells make antibodies, so the “recipe” is stored in immune system for when you come into contact with that pathogen

Vaccines States require specific vaccines http://vaccines.procon.org/view.resource.php?resourceID=005979

Vaccines work against diseases caused by both bacteria and viruses http://laughingsquid.com/a-ted-ed-animation-explaining-how-vaccines-work-to-help-the-body-stave-off-infections-illness-and-disease/
