#Vaccinology can trace its origins back to Berkeley, England. More than two centuries ago an English doctor, #Edward Jenner, immunized a young boy against smallpox by injecting him with pus from cowpox blisters on a milkmaid’s hands. Thanks to vaccines and the advancement of medical science many diseases have been brought under control. Let’s take a closer look at the contributions of some specific vaccines. 

Polio

This potential deadly and crippling disease is caused by the #poliovirus and can invade the brain and spinal cord, causing paralysis. The first polio vaccine (Salk vaccine) was developed in the early 1950’s by American physician Jonas #Salk, but the development of the vaccine did not come without incident. 

April 1955 saw more than 200 000 children in the US receive a vaccine in which the process of inactivating the polio virus was defective. The #Cutter Incident caused 40 000 cases of polio, paralyzing 200 children and killing 10. The Cutter Incident led to effective federal regulation of vaccines. 

Polio has been eliminated in the US with vaccination, according to the CDC, but it still poses a threat to children in some other countries. 

Hepatitis B

Known as the first “anti-cancer” vaccine, the #hepatitis B vaccine helps to prevent the leading cause of liver cancer. Dr. Baruch #Blumberg discovered the hepatitis B virus in 1965 and has since won a #Nobel Prize for his discovery. Irving Millman worked with Dr. Blumberg and helped to develop a blood test that can detect the hepatitis B virus. Four years after the discovery of the virus the first vaccine was developed. Globally, an estimated 884 000 people die from hepatitis B related complications according to the Hepatitis B Foundation. These figures would have been undoubtedly higher had it not been for the vaccine. 

Hib

The power of vaccines has virtually eliminated this disease which killed 20,000 children every year in the US. #Haemophilus influenzae type b mostly affects children under 5 years of age and can cause childhood #meningitis, blindness, paralysis, deafness, mental retardation and death. The vaccine was created by former medical chief David Smith and Porter Anderson and managed to nearly eradicate childhood bacterial #meningitis in America, Australia and several European countries. According to federal statistics Hib cases plummeted from 20,000 in 1987 to 81 in 1997. 

Anthrax and Rabies 

Louis #Pasteur first proposed the germ theory of disease back in the 1860’s. During the 1870’s an anthrax epidemic was present in France and other parts of Europe. Pasteur wanted to apply the principle of vaccination to #anthrax and in the spring of 1881 he obtained financial support to conduct a large-scale public experiment of anthrax #immunization. Pouilly-le-Fort, on the outskirts of Paris, played host to the successful immunization of 70 farm animals. 

During 1882 Louis Pasteur decided to tackle the problem of #rabies. Rabies was a dreaded and little understood disease. Suspecting that the disease was caused by a microbe, Pasteur would successfully vaccinate Joseph Mesiter on July 6, 1885, who had been bitten by a rabid dog. Hundreds of bite victims were saved by the vaccine and this is considered as the start to the era of preventative medicine. The vaccine was so successful that it brought fame to Louis and helped solidify his place in history. 

Rubella

This disease was declared eliminated as of 2004 in the US and transmission of the #rubella virus in the World Health Organization’s Region of the Americas was halted in 2009. Globally about 100,000 cases were reported for 2012 in WHO member states. As of 2010 a total of 131 countries representing about 42% of the global birth cohort use rubella-containing vaccines in their national immunization programs. Rubella-containing vaccine (RCV) is part of the national immunization program in Russia, most of Europe, China, Australia, the Americas and a few African countries. 

The chief danger from this disease comes in the form of Rubella Congenital Syndrome, which occurs when the rubella virus affects the developing baby, usually in the first three months of pregnancy. Babies can be born with birth defects if the mother is infected with the rubella virus, whilst mother are at risk of miscarriage and stillbirths. Since the introduction of rubella vaccine cases have decreased dramatically.

From the establishment of federal regulation of vaccines to the elimination of dangerous diseases, vaccines and their inventors have had a profound impact on the world of medicine, medical supplies and science. The spirit of constant advancement in science is perhaps best described by Louis Pastuer himself: “There are no such things as pure and applied science, there are only science and the application of science.”
