When your body fights a disease and wins, it tells the “plasma cell” everything about the disease, the plasma cell then keeps this information until the same disease attacks again. When the same disease attacks again, the plasma cell tells the B-lymphocyte cell all this information. The B-lymphocyte cell then makes “anti-bodies”. Anti-bodies are just like missiles and they attack just the disease from earlier and they kill the disease in an instant. Different types of vaccines have different things that tell the plasma cells everything about a specific disease before the body has even fought the disease so that the B-cell can make antibodies when needed. The following are 3 different things that different types of vaccines contain.
These vaccines have an alive but weakened form of the disease so that the body can fight the disease very easily but still get the information about the real and dangerous disease. They are made by altering the DNA of the disease over many generations of the disease in a complicated process.
