Immunization is the process of introducing a person to a weakened or inactive form of a germ (virus or bacteria) that causes a disease. This helps the body develop immunity to the disease, so that if the person is exposed to the real germ in the future, they will be less likely to get sick.
Vaccines are a safe and effective way to prevent infectious diseases. They work by exposing the body to a weakened or inactive form of a virus or bacteria. This triggers the body’s immune system to develop antibodies that can fight off the infection. When a person is later exposed to the real virus or bacteria, their immune system is already primed to fight it off.
Immunization is one of the most effective ways to prevent infectious diseases. It has helped to dramatically reduce the number of deaths and illnesses from diseases such as measles, polio, and diphtheria. Vaccines are also essential for preventing the spread of infectious diseases. When a large percentage of the population is immunized, it helps to create herd immunity, which protects those who are not able to be vaccinated, such as infants and people with weakened immune systems.
