Louis Pasteur, a french doctor, was the first to explain the principles of vacccination.
His first human vaccination was on a child against rabies in 1885.
But a century before, Peter Plett, a German teacher and Edward Jenner, a English doctor practised the first vaccination separetly at the same time.
They inoculated the vaccine (the cow version of variola) to people who will be acknowledeged as immuned against variola.
Some historians also say that inoculation of variola had already been made in ancient China.
Vaccination was not technically discovered. It was observed and then expanded by Edward Jenner. Edward Jenner noticed that milkmaids who got cowpox never caught smallpox. He injedted a boy with a small dose of cowpox, and when the boy recovered, Jenner gave him smallpox. The boy did not get ill. Jenner tried his experiment on approximately another 20 people before submitting his findings.

Whether or not it is safe to have a vaccine or not should be discussed with a physician. The answer depends on the specifics of your medical condition.

because there are different number of species with different effects that they can cause, therefore it is harder to develop a vaccine for it
