Importance of vaccine essay
Answers
Answer:
There has been confusion and misunderstandings about vaccines. But vaccinations are an important part of family and public health. Vaccines prevent the spread of contagious, dangerous, and deadly diseases. These include measles, polio, mumps, chicken pox, whooping cough, diphtheria, and HPV.
The first vaccine discovered was the smallpox vaccine. Smallpox was a deadly illness. It killed 300 million to 500 million people around the world in the last century. After the vaccine was given to people, the disease was eventually erased. It’s the only disease to be completely destroyed. There are now others close to that point, including polio.

What are vaccines?
A vaccine (or immunization) is a way to build your body’s natural immunity to a disease before you get sick. This keeps you from getting and spreading the disease.
For most vaccines, a weakened form of the disease germ is injected into your body. This is usually done with a shot in the leg or arm. Your body detects the invading germs (antigens) and produces antibodies to fight them. Those antibodies then stay in your body for a long time. In many cases, they stay for the rest of your life. If you’re ever exposed to the disease again, your body will fight it off without you ever getting the disease.
Some illnesses, like strains of cold viruses, are fairly mild. But some, like smallpox or polio, can cause life-altering changes. They can even result in death
