Smallpox
Cowpox
cowpox- humans can get it from cows, it doesn't kill you or give you any permanent illness. smallpox-it can kill humans and animals
cowpox is the antidote to smallpox-if you've had cowpox you can't get smallpox
1. With smallpox, the lesions begin centrally (on the trunk) and spread to the extremities
With chickenpox, the lesions begin on the face and then spread to the trunk
2. Smallpox: the lesions are all at the same stage (of development) at any given point in time
Chickenpox: the lesions are at various stages at any given time
3. Both smallpox and chickenpox: the lesions are widely distributed on the body
There are many differences from smallpox and chicken pox is that smallpox starts out severe with an illness, while chickenpox starts out with a rash. They both look the same but have different reactions, illnesses, and healing times.
Smallpox is a virus and syphilis is a bacteria.
cowpox gives immunity to smallpox. Jenner observed that people who worked with cattle and contracted cowpox from them.
The cure for smallpox is cowpox. Cowpox is a mild version of smallpox and is usually not fatal. The smallpox vaccine contains cowpox.
yes
Dr Edward Jenner injected small boy who had smallpox with cowpox, after hearing from a dairy maid that people who got cowpox would not get smallpox. This worked and that's how vaccination came about.
Well, I think it is the case that cowpox is just a lesser, bovine version of smallpox. Milk maids would get cowpox simply because they were exposed to cattle constantly, much more than the average person, who was more likely to get smallpox than cowcox. A scientist called Edward Jenner observed that milk maids, who often got cowpox, never seemed to get smallpox. This was because milk maids would develop immunity to cowpox (and therefore smallpox) once they had fallen ill and recovered from cowpox. He then tested this theory on a young boy. He did this by injecting cowpox into the boy's blood stream; the boy then fell ill with cowpox. After the boy recovered from cowpox, the scientist then injected him with the life-threatening disease smallpox. The result proved his theory right; the injection of smallpox into the boy's bloodstream had had no effect on him, because his body had developed immunity to the disease. If you wish to learn more about vaccination and immunities, then research antibodies, antigens and vaccination and the way in which they all work.
Cowpox. Edward Jenner inoculated a boy with cowpox in early discovery of smallpox vaccine, it is part of the Vaccinia virus family
Cowpox was a less harmful version of smallpox. So their bodies created antibodies for the cowpox which in turn could kill the smallpox cells.
Louis PasteurEdward Jenner found that people who contracted the cowpox virus didn't contract smallpox so he tested it out on a farmer's son who had contracted smallpox that week and he applied the liquid inside a cowpox sore to a cut and then after he healed from cowpox, he injected the liquid from a smallpox sore and the boy didn't contract smallpox.Which is how he found the vaccine...Note: Developed not invented
Cowpox is a virus that causes blisters, similar to smallpox. It was most commonly seen in 'milk maids' - young female workers that milked dairy cows for a living - so it was called cowpox. In the 1800s, a physician noted that milk maids who had recovered from cowpox did not contract smallpox, and the first vaccine was developed.
The smallpox vaccine was the first successful vaccine to be developed. Edward Jenner observed that milkmaids who caught the cowpox virus did not catch smallpox. He started testing by infecting people with actual Cowpox and after successfully finding this to be effective, "mass infecting" people with Cowpox took place. This reduced mortality by Smallpox drastically. Cowpox and Smallpox are closely related but Cowpox only gives the disease in a very mild form in humans. This most likely because it has developed towards cows and not humans. Diseases do not cross the species barrier easily. As a result of the similarities between the two, human bodies start building up an immune respons against both diseases even if only Cowpox is present. Read more at related link below.

An English doctor by the name of Edward Jenner. He noticed that milkmaids got cowpox which was similar to smallpox, but much milder, and after a milkmaid had had cowpox, she did not get smallpox. So Dr Jenner tried to scratch the skin of volunteers with a needle dipped in to cowpox germs. The volunteer got a transient mild illness and did not get smallpox after vaccination. When Dr Jenner's vaccine was shown to be so effective, vaccination against smallpox became compulsory. Smallpox is now almost entirely eradicated and most counties stopped making smallpox vaccination compulsory in the late 70s and early 80s.
