His experiments supported the germ theory of disease, also reducing mortality from puerperal fever (childbed), and he created the first vaccine for rabies.
We can not eradicate all the mosquitoes that carry it. If we wipe out an entire species in an ecosystem, we may cause more problems. The best we can do is to produce a vaccine or a very good treatment.

Vaccines are weakened/disabled forms of the virus. You need to train your body to take care of the pathogen naturally. Sometimes this works best if exposed to small doses over a long period of time.A booster shot is simply another dose of the vaccine.
Vaccines have a minuscule amount of the disease, so your immune system can easily destroy it and then retain in the immune systems memory the best way to destroy it. That is how vaccines work. However if you have an immune deficiency disorder, or a weak immune system, the disease inside the vaccine has a tiny chance of surviving and reproducing causing the disease to infect you.
