As most people know, we wear seat belts while driving to protect us from injury in the case of a car accident. Unfortunately, sometimes people are harmed in an accident even when they have taken preventative measures, like using a seat belt. But we can all agree that seat belts are a crucial protection because they drastically reduce the chance of serious injury, even death, from a car accident.
The same principle applies with vaccines and immunizations. Think of a vaccine like a seat belt. While nothing is 100 percent effective and there’s no guarantee against exposure to disease, modern vaccination offers high levels of protection against disease.
