There are quite a few ways to become immune to smallpox. One way is that you can be infected with the disease Cowpox. Which is not deadly in anyway but is a disease nobody wants to have. Another way is, you can infect your self with smallpox and give yourself a mild case of it. It is proven that once you had smallpox and you survived you never get it again, by infecting yourself mildly you can become immune to it.
Correction mild case of smallpox is cowpox if u become infected with cowpox u become immune to smallpox and cowpox for the rest of your life it is like a vaccination but instead of being shot with it u actually become sick but once you get over it your completely immune to it or any other more serious case of the illness.
No. After you get a disease like smallpox, your body is able to develop permanent defenses against it. This makes you "Immune" to the disease. This is the principle on which vaccines work.
Edward Jenner discovered that farmers who had caught cowpox did not suffer from smallpox. He then started injecting people with small doses of cowpox and he observed that they did not catch smallpox. He had created a vaccination for smallpox. :D

The natives did not have advanced technology and the Spanish carried diseases such as smallpox that they had grown immune to but these diseases were new to the natives and killed many of them before they even went out to battle
Smallpox is caused by the variola major virus
no
One can be infected by smallpox if a victum of smallpox has coughed in the air. They can be infected by smallpox by exposing an opened wound. You can become infected if you breath the air that is shared by someone that has smallpox. Its passed many different ways.

It helps it gain immunity
he put some of the smallpox virus into the other soldiers to make them become immune to the virus.:)
African Slaves were immune to it and the origin is unknown?
Anyone not immune to the virus (not a common virus anymore though)

Because immune system is weak in children than elders.
Yes. He noticed how milkmaids caught cowpox, but didn't get smallpox. Cowpox was similar to smallpox but much milder so didn't kill people who caught it. The milkmaids who had caught cowpox didn't catch smallpox because their body had become immune to it after having cowpox. To test this theory, Jenner took some of the pus from a cowpox spot from a milkmaid and injected it into a boy named James Phipps. He fell ill, but didn't die. He then recovered and Jenner took the pus of a smallpox spot, in a high dose, and then injected this into James phipps. This was very risky because smallpox at the time was very deadly. James Phipps did not fall ill. The cowpox had made him immune to smallpox. This vaccination was done on more and more people to make more people immune to smallpox.
Because James Phipps had never had Smallpox and Jenner needed somebody who was not immune to smallpox or else this experiment would not work.
John Doe was not immune to irrational thinking but liked to think of himself as a throughgoing rationalist. Vaccination will make you immune to smallpox, but you will need a booster shot after a few years.
It's NOT for people with skin disorders, like eczema, and other immune disorders.
