You're misunderstanding though, it only works on certain strains of HPV, for the unaffected strains we wouldn't expect a reduction in incidence. You are thinking of Herd Immunity, which is what allows for a disease to be wiped out and protects unvaccinated/immunocompromised individuals in a population.
- sjwright 9y agoThe article indicates that the vaccine provides a minimum of 50% reduction in all variants of HPV.
- masonic 9y agoNo, it projects a 50% reduction in disease caused by HPV without giving supporting science. The bivalent vaccine does not prevent infection with other strains (it can't; it doesn't work via recruiting the immune system like most vaccines do).
