The measles vaccine is one of the most important medical advances of the last century. It has been responsible for saving millions of lives by preventing the spread of a potentially deadly disease. The World Health Organization estimates that since 2000, over 20 million deaths have been prevented due to the introduction and use of measles vaccines. In addition to this, it has also helped reduce the rate of hospitalization and disability associated with measles infections. Vaccination remains the most effective way to protect yourself and your family against this highly contagious virus.
