ANATOMY

Detailed explanation-1: -Macrophages are white blood cells that swallow up and digest germs, plus dead or dying cells. The macrophages leave behind parts of the invading germs called antigens. The body identifies antigens as dangerous and stimulates antibodies to attack them.

Detailed explanation-2: -MMR vaccine is very effective at protecting people against measles, mumps, and rubella, and preventing the complications caused by these diseases. People who receive MMR vaccination according to the U.S. vaccination schedule are usually considered protected for life against measles and rubella.

Detailed explanation-3: -For example, in response to an infection or vaccination with a live virus, IgM antibodies usually are made first, followed by IgG and some other types of antibodies. For the most part, the antibodies that you form from getting vaccinated are the same kind of antibodies you would get from a natural infection.

Detailed explanation-4: -White cells respond more quickly, so antibodies are produced sooner, which can stop you from becoming ill again. Lymphocytes can also produce anti-toxins to neutralise toxins released by some pathogens. Antibodies and anti-toxins are highly specific.
