U.S. health officials say some diseases are almost gone from the U.S., but we need to continue to immunize our children and ourselves.
Some diseases, like polio and diphtheria, are becoming very rare because we have been vaccinating against them. But that does not mean we should stop vaccinating. There is still a chance for a disease to go back up unless is fully eliminated.
For example, our children now no longer need to be vaccinated against “smallpox” because we eradicated the disease. If we continue to do the same for other diseases hopefully their effects will come to an end too.
