A History of Vaccinations

There has been a lot of talk surrounding vaccinations in the past few years, especially during the COVID-19 pandemic. With many boasting selfies with their filled-out vaccination cards and proudly bearing side-effects, and new medications being developed in record time, it is easy to forget that inoculation has been a prominent discussion for thousands of years. The vaccination process has obviously come a long way, so let’s take a moment to stroll back in time, through the history of vaccinations.

Early Inoculation

Though the exact date is unknown due to varying reports, some sources claim that inoculation started as early as 200 BCE in China. Most reports of these early inoculations, however, come from 14th and 15th century China, in which smallpox scabs would either be ground to a powder and snorted up the nose or matter from within smallpox sores would be rubbed into deep scratches made in the skin.

Moving Forward

By 1796, Edward Jenner had begun testing a similar process in Europe. Jenner studied arm-to-arm inoculation, which consisted of taking one blister from one individual infected with cowpox and implanting it in the skin of another. Those undergoing early forms of arm-to-arm inoculation could expect three weeks of devastating side-effects. However trying, though, these weeks of fever, chills, and expelling bodily fluids of all sorts were, they were seen as a welcome alternative to death by smallpox.

This process largely remained the height of vaccination progress until the late 1840s, when general scientific knowledge had advanced enough to accommodate large-scale vaccine production. After the founding of the smallpox vaccine, scientists around the globe rapidly began finding new solutions to long-standing illnesses.

Modern-day Vaccines

Most traditional vaccines still mimic this arm-to-arm inoculation process, on a less grotesque level. By injecting the body with either a weakened form of a disease or an imitation disease, the body’s immune system and natural defenses kick in and learn how to effectively attack these foreign particles. Then, when the real deal enters the body, the immune system already knows how to identify and attack the disease and can better fight it off.

The newest vaccine, which helps fight against COVID-19, is the first of its kind: an mRNA vaccine. While the Johnson & Johnson vaccine follows traditional methods, both the Moderna and Pfizer vaccinations teach the body’s defenses to create, recognize, and destroy a replica of the protein found on COVID-19 molecules’ spikes. Many scientists believe that we will begin to see more of these revolutionary mRNA vaccines in the future.
