It was Edward Jenner.
One potential biological warfare agent that is a virus is smallpox. It is highly contagious and has the ability to cause severe illness and high mortality rates within populations. Its aerosolized form can potentially be used as a weapon to infect large numbers of people.
Smallpox had a far more devastating effect in the New World, where it occurred as epidemics. The first recorded smallpox outbreak in Latin America occurred in 1507, when Spanish explorers brought the disease to Hispaniola. The natives lacked immunity to smallpox and entire tribes were extinguished. The population of Hispaniola, estimated to be 300,000 in 1492, had reportedly decreased to less than a 1,000 by 1541. 4 During the following decades Spaniards were able to conquer the Aztecs and the Incas, who, despite their large armies, sooner or later succumbed to smallpox. Historians cite from 2 to 15 million Aztec deaths due to smallpox.5Smallpox moved northward from Mexico and westward from the eastern populations of the United States and Canada.4 By the mid-1800s, smallpox had decimated many Native American tribes from United States, Canada, and Alaska.
Smallpox killed millions and a large number of children died from it. The vaccine saved a lot of lives and many who lived because of the vaccine were able to contribute to society as adults.
There are large number of viruses causing common cold. So to have protection from common cold you have to immunize the person for all the viruses responsible for it. Which is not practical and it is not desirable also. As common cold is relatively trivial condition.
Beriberi is primarily caused by a deficiency of thiamine (vitamin B1) and can be treated with thiamine supplements. However, there is no vaccination specifically for beriberi. Proper nutrition and thiamine-rich foods can help prevent beriberi.
These days, smallpox exists only in a few dedicated research laboratories in the United States and Russia, and a couple of other places. "In the wild", smallpox is extinct, the first major worldwide disease to be eliminated. Before about 1900, smallpox could be easily transmitted by casual contact; breathing the same air, sharing the same blankets, or by touch. It was wildly virulent and quite deadly to its victims. In pre-1400s Europe, smallpox was a serious disease, but most people had developed at least a little resistance because of repeated contact. When Europeans began to travel the world, smallpox traveled with them. Smallpox had never existed in the Americas or in much of Asia, and the arrival of smallpox was deadly to large numbers of people, who had no resistance to it.
Rabies has not been found to be contagious from person to person. In theory, if a person infected with rabies were to bite someone else, the virus might spread, but no such cases have been recorded.
In 1967 the World Health Organization (WHO) started a worldwide campaign to eradicate smallpox. This goal was accomplished in 10 years due in a large part to massive vaccination efforts. The last endemic case of smallpox occurred in Somalia in 1977. On May 8, 1980, the World Health Assembly declared the world free of smallpox.
The Greek word for "Large Person" is "μεγάλο πρόσωπο".

In young children they are usually given in the large muscle of the lateral thigh. If the child is developed well enough to have good muscle tissue available in the arm, they can get the vaccination in that muscle. The clinician who is giving the flu vaccination will make the decision for the patient at hand on the best site of the injection.
