Vaccines

Vaccines. The ruthless plot to pacify the population...

Not really. Vaccines are designed to make your immune system find the most efficient ways to kill viruses. Vaccines prevent viruses, while antibiotics treat bacteria. Antibiotics not do work on viruses, increasing the need for vaccines. Vaccines are either:

1. A non-harmful version of the virus strain injected into the body
2. An artificial version of the virus that acts and behaves like the virus, but is not harmful

If your immune system has knowledge of the most efficient ways to kill a virus, it is very unlikely that the virus will cause an infection.
