Immunization is one of the best ways you can protect yourself, your children and future generations from infectious diseases. In other words, if you vaccinate, you help wipe out diseases that could spread now and into the future. Immunization saves lives.
The vaccination uses your body’s immune system to increase protection to an infection before you come into contact with that infection. In other words, it is like being infected with the disease without suffering the actual symptoms.
If you come into contact with an infection after you’ve been vaccinated, your body works to stop you from getting the disease, or you may get just a mild case.
