Antibiotic resistance

.... Nevertheless, new strains may evolve that escape immunity induced by vaccines. While theoretically promising, anti-staphylococcal vaccines have shown limited efficacy, because of immunological variation between Staphylococcus species, and the limited duration of effectiveness of the antibodies produced. ...
