Key Takeaways<\/h2>\n

Hailed as one of the greatest discoveries in the history of mankind, vaccines help our immune system protect us from diseases. They are especially effective against\u00a0communicable or infectious diseases,\u00a0<\/a>which are easily spread among populations.<\/p>\n\n <\/div>\n <\/div>\n<\/div>\n\n\n

Mandatory vaccination laws help halt the spread of communicable diseases by ensuring that a critical mass of persons enjoys immunity from vaccine-preventable diseases. Before the invention of vaccines,\u00a0infectious diseases claimed countless lives.<\/p>\n

Mandatory vaccine laws aim to ensure everyone has a similar level of immunity from vaccine-preventable diseases. The\u00a0COVID-19 pandemic, along with\u00a0subsequent vaccines,\u00a0offer\u00a0proof of their effectiveness. Enforced by public health officials, mandatory vaccinations\u00a0helped this\u00a0vaccine to achieve a critical mass.<\/p>\n

The following article explores U.S. vaccination laws, including exemptions to such mandates and key court cases.<\/p>\n

Understanding Vaccines<\/strong><\/h2>\n

Your immune system consists of\u00a0white blood cells<\/a>\u00a0and organs that protect you from external germs and diseases. If you fall and scrape your knee,\u00a0the resulting\u00a0open wound\u00a0leaves\u00a0you vulnerable to a host of germs. Your white blood cells will rush to the wound to protect you from a possible infection.<\/p>\n

Although your immune system is quite powerful, it often needs help to protect you. Vaccines help your immune system fight\u00a0dangerous diseases like measles and\u00a0smallpox. Dr. Edward Jenner, a British physician, created the first successful smallpox vaccine in 1796. Scientists have built on Jenner’s\u00a0success and developed\u00a0vaccines to combat\u00a0communicable diseases like measles and polio.<\/p>\n
