Vaccines are special medicines that help protect us from diseases. They work by teaching our immune system how to recognize and fight off harmful germs, like viruses and bacteria. When we get vaccinated, our body learns to defend itself, so if we encounter the real disease later, we are less likely to get sick.
There are many types of vaccines, including those for measles, flu, and COVID-19. Getting vaccinated not only helps keep us healthy but also protects others in our community, especially those who cannot be vaccinated, like infants or people with certain health conditions.
