What is an "antibody"?

You might remember back to high school and college biology when you learned about the vaccines and you learned about why you get the measles vaccine and why you get now a chicken pox vaccine and all these vaccines that we get throughout childhood if we are believers in vaccines. Vaccines are exposing your body to a particular protein component of a disease and having your body, your B cells and T cells which are part of the immune system produce antibodies against or basically a product to block the protein that's abnormal or to block the disease. So by exposing your body to a nonlethal or nonpathogenic, nonharmful portion of a disease whether it be measles, mumps, rubella, chicken pox, yellow fever. You know there's tons of vaccines, your body goes ahead and makes antibodies or blocking products, a blocking protein to block or destroy the abnormal protein or pathogenic or harmful protein that may enter your body. Every year you may or may not get a flu vaccine. A flu vaccine has components or protein components of all the particular flu viruses that have been found across the world.
