Document Summary
One disease eradicated > smallpox (through vaccines) More than 4 million people diagnosed with measles. In 2000 measles were all but eradicated. Introduced by erik jenner > cowpox and smallpox (1796) Vaccine as a suspension of live (usually attenuated) or inactivated microorganisms (e. g. bacteria of viruses) or fractions thereof administered to induce immunity and prevent infectious disease or its sequelae . A vaccine contains a weakened or killed microorganism. Causes your body to boost its immunity to a certain disease. A vaccine tricks your body into thinking it"s being invaded by a disease-causing agent so that your body will build up its defenses. As a result, your immune system will remember the disease-causing agent and promptly attack and neutralize it if it reappears. 1905 example, the u. s. supreme court ruled in jacobson v. massachusetts that the need to protect the public health through compulsory smallpox vaccination outweighed the individual"s right to privacy.
