We've had vaccines since 1796 [0] when Edward Jenner developed a vaccine for smallpox, a terrible disease that we fully eradicated thanks to vaccination. A disease that you and me don't have to worry about because of vaccines.
(Likewise for Cholera, Tetanus, Polio, Tuberculosis, Meningitis, etc)
Also, trains, cars, planes, cameras, lightbulbs and every invention of Edison are newer technologies than vaccines.
