Vaccination
Vaccination is a medical process that helps protect people from infectious diseases. It involves introducing a small, safe amount of a virus or bacteria, or a piece of it, into the body. This stimulates the immune system to recognize and fight the disease. If a vaccinated person is later exposed to the actual disease, their immune system is prepared to respond quickly and effectively, preventing illness. Vaccinations have played a crucial role in reducing, and in some cases eradicating, serious diseases like smallpox and polio, contributing to public health and safety worldwide.

Vaccination is a medical process that introduces a harmless part of a disease-causing germ, like a virus or bacterium, into the body. This stimulates the immune system to recognize and fight the germ without actually causing the disease. If a vaccinated person later encounters the real germ, their immune system can respond quickly and effectively, reducing the risk of illness. Vaccines are a crucial tool in preventing infectious diseases, protecting both individuals and communities by limiting the spread of infections and helping achieve herd immunity.
