It's not just antibiotics, but some types of vaccines are creating evolutionary pressure and new strains of the pathogen. E.g. for pertussis
> it is thought that B. pertussis is adapting under acellular vaccine mediated immune selection pressure, towards vaccine escape [1]
> an increase in asymptomatic infection with concomitant increases in transmission and increased selection pressure for Bordetellapertussis variants that are better able to evade vaccine-mediated immunity than older isolates [2]
