NEW definition of vaccine from the CDC
Vaccine: A preparation that is used to stimulate the body's immune response against diseases. Vaccines are usually administered through needle injections, but some can be administered by mouth or sprayed into the nose.
whelp… i'm no lawyer, but i do believe that according to the CDC's new definition of a vaccine, the half-dozen or so natural supplements wifeanon and i take, which are proven to boost the immune system, qualify as vaccines. therefore, by taking them, we are vaccinated, according to the CDC.
