Training the Immune System

Vaccines work by teaching your immune system how to fight off specific viruses or bacteria without making you sick. They usually contain a harmless part of the germ, like a weakened version or just a small protein. When the vaccine enters your body, your immune system reacts by creating antibodies, which are like special soldiers designed to attack that germ. If you’re exposed to the real disease later, your immune system remembers how to respond quickly, preventing you from getting seriously ill.

Building Community Protection

Vaccines don't just protect individuals they help protect entire communities through something called herd immunity. When enough people are vaccinated, diseases have fewer chances to spread, which helps protect those who can’t get vaccinated, like babies or people with certain health conditions. Thanks to vaccines, diseases like smallpox have been wiped out, and others like polio and measles are now rare in many countries. Staying up to date on vaccinations is a simple but powerful way to keep yourself and others safe. Shutdown123
