You probably have memories of getting vaccinations when you were younger, and some of you remember when they were a new thing. When vaccinations became widely used to prevent people from getting sick, it was an exciting step forward in medical science. We no longer had to worry about terrible, contagious diseases like small pox, mumps, polio, and many others that people were afraid of getting.
Today, some people have begun questioning whether or not they might be causing more harm than good, especially in children. However, the medical community still completely backs the administration of vaccines, saying that their benefits far outweigh any risks.
