CALLING ALL THE
SHOTS SHOTS Let's talk about vaccinations.
What do they do? Vaccines train your body to fight specific infections. This, in turn, protects against certain infections, or reduces the severity of such infections if they are ever developed in the future.
How do vaccines work? Vaccines usually contain a version of a viral particle or bacteria that may either be killed or modified in some way. Some vaccines may incorporate only a specific part of the virus or bacteria. As a result, the virus or bacteria in the vaccine are made much weaker, and are unable to cause full-blown illness.
However, the immune system will still fight against them. This reaction is known as an immune response.
This immune response allows the immune system to form memory against these viruses or bacteria and the know how to fight them, in case they are ever re-encountered in the case of a true infection.
