Development in History of vaccines
“The reward for work well done is the opportunity to do more.” — Jonas Salk”.There is an enormous difference in vaccines from time to time. These vaccines help in curing diseases and viruses. There are different vaccines for curing individual problems. But the question is how do they work and how did scientists make them? Edward Jenner is considered the founder of vaccines in the West in 1796. He invented a method that involved taking material from a blister of a person who was infected with cowpox and inoculating it to another person’s skin which was called arm-to-arm inoculation and demonstrated immunity to smallpox. His method underwent medical and technological changes over the next 200 years and eventually resulted in the eradication of smallpox. Later in the 1940s, the knowledge of science had grown enough that large-scale production was possible and the disease was put to an end. Louis Pasture’s 1885 rabies vaccine was the next to make an impact on human diseases. The middle of the 20th century was an active time for vaccine research and development. Methods for growing viruses in the laboratory led to rapid discoveries and innovations, including the creation of vaccines for polio. Researchers targeted other common childhood diseases such as measles, mumps, and rubella, and vaccines for these diseases reduced the burden greatly.
Another thing that is known as the common cold was something in the past that killed many people just because they did not have a vaccine, which tells us how important vaccines are in our lives. Nowadays the vaccines that we have been in the form of tablets. Different ingredients kill the cells of the disease in our bodies. Some tablets are only for adults so we also have medicines in the form of liquid for kids. As we can see the medicines these days are more advanced than those in the past. People in the past used nature as their medicines. The oldest written evidence of the medicinal plant used for the preparation of drugs has been found on a Sumerian clay slab from Nagpur, approximately 5000 years old. It comprised 12 recipes for drug preparation referring to over 250 various plants, some of them alkaloids such as poppy, henbane, and mandrake.
Innovative techniques now drive vaccine research, with recombinant DNA technology and new delivery techniques leading scientists in new directions. Diseases targets have expanded and some vaccine research is beginning to focus on non-infectious conditions such as addiction and allergies. An additional piece of information is that Hippocrates of Kos was a Greek physician commonly known as the father of medicines. He studied the human body and was a great physician in his time.
All in all the first vaccine ever made was by Edward Jenner to cure smallpox. After some time the science became more advanced and smallpox was put to an end. Vaccines are very important in our lives. Many shreds of evidence were found telling that people in the past used nature as medicines. From time to time our medicines became more and more advanced. This report holds development in the history of vaccines. Nearly all the information is in this report but the points left were to provide a broad view. “The information never ends.” — unknown
