diseases that have been eliminated due to vaccinations
Once high levels of routine immunization have been achieved, national immunization days, followed by close monitoring and 'blitzing' of any outbreaks, can eliminate the disease. In all, vaccines have brought seven major human diseases under some degree of control - smallpox, diphtheria, tetanus, yellow fever, whooping cough, polio, and measles.
