But--how long ago had these people been vaccinated? Isn't it commonly believed that vaccinations lose their potency after 20 years or so? I know there is conflicting information on this, as studies of at least one outbreak showed that vaccinations actually protect longer than the medical community has thought true. We need more information here.
