The injections may sting a little … But the diseases they can prevent can hurt more! Immunizations or vaccinations are essential. Protect against diseases like measles, mumps, rubella, hepatitis B, polio, diphtheria, tetanus and pertussis (whooping cough). Vaccines are important both for adults as for children.
The immune system helps your body fight germs by producing chemicals to combat them. Once you do, the immune system “remembers” the germ and can fight him again. Vaccines contain dead or weakened germs. When given a healthy person, the vaccine triggers an immune response to respond, creating immunity.
Before vaccines exist, people could only be truly immune when contracted the disease and survived it. Immunizations are an easier and less risky to be immune.
