5. Vaccines Are Part of Amazing Medical Breakthroughs
The history of modern vaccines began in the late 18th century with the discovery of immunization against smallpox. It started with Doctor Edward Jenner when he took cowpox and inoculated a young boy; as a result, the boy became immune to smallpox. It started the discovery of using weaker versions of viruses in order to help people develop an immunity against the more potent virus. Then in the 20th century, vaccines for polio were developed and helped to change the world’s fight against this horrible infection. Contracting polio could lead to spinal paralysis and muscle weakness.
Since then, researchers have made strides in developments with other vaccines. Some include tetanus, the flu, diptheria, measles, mumps, and rubella, just to name a few. The creation of these vaccines has helped children from young ages develop immunity to these diseases. That way, they have a chance to live well into adulthood. Clinics offer flu shots every year at the beginning of the flu season. They help decrease the risk of infections and help people fight off the symptoms. Thanks to vaccines, it has become more difficult for viruses to spread. Not only that, but vaccines have allowed people worldwide not to contract these deadly diseases.
