Immunization and Vaccines
MEDICAL ANIMATION TRANSCRIPT: Immunization is the process of becoming immune to or protected against a disease, usually by receiving a vaccine. Vaccines stimulate your immune system to protect you from certain diseases so you won't get sick or get an infection. Vaccines can protect you from getting these diseases and their harmful symptoms. Vaccines often contain a small amount of weakened or killed germs, but some contain genetic material, such as RNA or DNA, that provide instructions for your body's own cells to make the germ's antigen. Usually, you receive a vaccine as a shot. Inside your body, the germ particles in the vaccine teach your immune cells to attack these germs. This process doesn't make you sick, but it does cause your body to make memory cells and antibodies for those germs. As a result, if that germ infects your body later in life, your immune system is ready to fight the infection so that you don't get sick.
