Yep you heard that right, vaccines are not just for children. New vaccines keep developing as new diseases are introduced in human population. Few to name are: Tetanus, Pneumonia, Meningitis, HPV, Flu shot and COVID-19 vaccine. "Immunizations are the greatest medical advance of the last one hundred years," says Richard L. Wasserman, MD, PhD. Thanks to numerous immunization programs we've successfully wiped out diseases that were once life threatening. How does it work? Many vaccines work by introducing a dead or weakened version of a germ into your body, allowing your body to become familiar with it. Your immune system then reacts by creating antibody proteins custom-designed to fight that particular microbe. Then, if you ever come into contact with the real germ, the antibodies attack it. This is how vaccines grant you immunity. Once you're in your 30's or 40's its potency wears off and so you need a booster shot. Its always a good idea to keep your immunization schedule up to date in order to protect yourself and your loved ones. Happy Vaccinating!
