What Are Vaccines?
You know that vaccines are important and help fight diseases, but do you scientifically understand what they are and do? Immunization vaccines help you build your body’s natural immunity to a particular disease. Basically, the vaccine will keep you from getting sick, which will help stop the spread of the disease. You can see many examples of this throughout history, such as polio, measles, mumps, chickenpox, and, most recently, the flu vaccine.
When a vaccine is injected into your body, you’re given a weakened form of the disease. From there, the antibodies inside of you start fighting off the germ, which makes you immune from the disease for some time. You might have these antibodies for a few years or the rest of your life.
