Training the Body to Fight Germs
Vaccines protect us by teaching our immune system how to fight harmful germs without making us sick. A vaccine contains a tiny, safe part of a germ or something that acts like it. When it enters the body, our immune system learns to recognize it as an invader. This way, if the real germ shows up later, the body knows exactly how to fight it quickly.
Long-Lasting Protection
Some vaccines protect us for many years, while others require booster shots to maintain the immune system’s readiness. Vaccines not only help the person who gets them but also protect the community by stopping germs from spreading. This is called herd immunity, and it helps protect people who can’t get vaccinated, like newborn babies or those with certain illnesses.
