Immunizations and vaccinations protect against disease by:

disinfecting contaminated surfaces

preventing the transmission of disease from one person to another

are present beneath the fingernails where they cannot be reached by alcohol- based hand sanitizers

have already been passed from the health care worker to a patient

are present only on the surface layers of the skin and can be easily washed off

have penetrated to deeper layers of the skin and are much harder to remove or kill
