Anti-vaxx: Are these diseases making a comeback?

Vaccines have saved millions of lives by eradicating or slowing the propagation of numerous illnesses. Without scientists like Edward Jenner (1749-1823), the father of immunology, and Louis Pasteur (1822-1895), the father of vaccination, diseases such as smallpox and tetanus would still cause thousands of deaths each year. The World Health Organization (WHO) estimates that vaccines saved the lives of at least 10 million people between 2010 and 2015. While several illnesses have apparently disappeared from the face of the earth, some diseases have seen a comeback in recent years. Authorities lay most of the blame on the anti-vaccination movement. Which diseases have vaccines eradicated? Which ones are experiencing a resurgence? Read on to find out.
