@oralloy,
Quote:What is wrong with the term "vaccine"?
Nothing. I was just pointing out that the previous definition (prior to my last post) was not applicable to any of the mRNA 'jabs' developed for COVID-19.
The CDC changed the definition of the word 'vaccine' to include them on or about the date of my post.
One of the key changes was that previously, a vaccine was to provide immunity to a single strain of virus. The Covid-19 shot does not provide immunity, but it does boost the body's own immune response to multiple virus strains. That’s why it works on delta, mu, etc, as well as the original.
And of course previously, a vaccine provided virtually permanent immunity, the Covid-19 shot is apparently only short term (< 1 year) help.
How many polio vaccine shots did you get?
