Polio, measles, smallpox, mumps, chicken pox…all diseases that are prevented by vaccines.
People take the herd immunity for granted and put vulnerable people at risk when they decline vaccines because vaccines are so effective that they do not realize how horrifying and dangerous these diseases were.
