Well … I think that’s a sense that has emerged. Say the word “vaccination” and most people think “inoculation” which does mean prevention. However (as Wikipedia points out) although people use vaccination and inoculation as if they are interchangeable, they are two different things. Medical experts believing that everyone is as educated in the different terminologies as they are have used “vaccination” in its precise and technical meaning while lay people (almost all of us) thought they meant inoculation. It’s the old “assume = make an ass of you and me” problem
The various COVID vaccines are just that - vaccines - not inoculations
