You made up a definition of what ‘vaccine’ means then decided that covid vaccines don’t meet it.
The vaccines do a pretty good job at preventing morbidity and mortality. Feel free to sue someone if you disagree and if American tort law allows it.
That is what the word vaccine means to ordinary people. Stop accusing me of changing a definition that your side is changing. [1] That kind of behavior belongs on Reddit.
Merriam Webster's old definition excluded many vaccines ordinary people called vaccines. Diphtheria and tetanus most clearly. And other dictionaries had definitions compatible with mRNA vaccines.[1]
