Vaccines may well be considered as some of the most important discoveries and inventions ever achieved by man. It is sad that oftentimes these are not recognized as such. Instead, it is often that other technological advances are given this recognition. The truth, however, is that vaccine development has resulted in the saving of millions of lives. This alone should already be enough bases why vaccines should be treated as such.
Now, there are many vaccines but the very first was one that was meant to cure smallpox. This was the result of the study made by Edward Jenner when he was curious about the statement of a milkmaid who said that because she had contracted a milder disease, cowpox, she would not be affected by small pox. When Jenner inoculated someone with a pus from the milkmaid, who happened to be infected with cowpox, he confirmed the truth of the milkmaid's statement. This discovery brought about the creation of the world's first vaccine, one which ultimately helped millions worldwide and now smallpox is virtually irradicated.
Vaccines can be differentiated into different types. The differentiation may be based on how these work in order to protect people from a number of diseases while triggering the immune system to work its best against harmful microorganisms. Killed, toxoid, attenuated, conjugate, valence, subunit, and experimental are the different types. The difference between killed vaccines and attenuated ones is that the former is made up of microorganisms that is already not capable of doing harm while the latter is made of live microorganisms that do not have the bad qualities any more.
A toxoid vaccine originates from a toxic compound, which makes it different from other vaccines that have micro-organisms instead. Subunit vaccines, on the other hand, are those made of fragments of positive micro-organisms. Conjugates contain bacteria that have barely immunogenic polysaccharide outer coats. Just by the term, it is clear that experimental vaccines are those that are still not in the vaccine production stage.
These vaccines may be different from each other but they do share one common purpose and that is to prevent harmful microorganisms from rendering damage to humans. The similarity is also stretched to the fact that all these are basically biological in nature. The toxoid vaccine also comes from plants or animals with toxic qualities.
These may have other basic differences but there is no doubt that these have helped people enjoy longer lives. It cannot be denied that these are signs of man's victorious struggle against various types of diseases, fatal or otherwise. The promise of further vaccine development though is bright since people would always strive to keep themselves free from any disease.
