One of the greatest success stories in public health is how vaccines have reduced infectious diseases. Routine immunization has eradicated smallpox from the globe; led to the near elimination of wild poliovirus; reduced preventable infectious diseases to an all-time low; and minimized the number of people that experience the devastating effects of measles, pertussis and other illnesses. Vaccines are highly effective in preventing death and disability. They also save billions of dollars in health costs annually.
A decision to vaccinate is a decision to help protect individuals and entire communities from diseases spread by person-to-person transmission. When immunization programs achieve high levels of community immunity, the likelihood that an infected person will transmit the disease to a susceptible individual is greatly reduced
