An article in the National File reports a change by the CDC in another basic definition on their website as COVID-19 continues to infect the vaccinated.
The CDC definition as of May 16, 2018:
Vaccine: A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease. Vaccines are usually administered through needle injections, but can also be administered by mouth or sprayed into the nose.
On September 1, 2021 the CDC definition was changed:
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.
