- COVID-19 Spreads by human to human contact sneezing and coughing from people.
- What causes COVID-19 and how does it spread?
- The virus replicates itself by tricking a cell and attaching itself to the cell so it can go inside and make copies of itself to make more.
- When a person gets tested for the virus they try to look for things that the virus has like the proteins of the virus or RNA strands.
- The virus changes slightly overtime by mutating. These mutations can either make differences like whether it's more deadly or contagious or if it's less contagious and so on.
- Antibodies are Y shaped proteins used by the immune system to fight off and neutralize foreign objects and invaders like diseases.
- Once the vaccine reaches your cells your white blood cells aka your immune system will start to notice that the thing it saw isn't supposed to be there. The white blood cell then gets rid of it and your body stores it as part as the memory cells to remember that we need to fight it off and not let it inside.
- The body responds to the vaccine by realizing the proteins aren't supposed to be in there so it gets rid of it it's pretty much ready if it ever comes in body again that way the immune system can be ready to fight it and get rid of it as fast as possible.
