Answer:
Although vaccinations for certain preventable diseases are now widespread in the United States, this doesn't warrant relaxing their use. Disease outbreaks continue to happen around the world. And even in the U.S., some communities have experienced a resurgence of some preventable diseases when vaccination rates are low.

The more people who get vaccinated, the safer communities will be overall. Easily transmitted diseases are still capable of growing fast, so other people's health is often dependent on our own self-care. This shows the importance of vaccination, because you have the power to protect yourself and others against the flu, measles, mumps, and many other vaccine-preventable diseases.
