There were plenty of protein subunit vaccines and a few viral vector vaccines in use in humans prior to the COVID vaccines. Neither of these are dead pathogens.

it started as live pathogens (cowpox) so it must have gone through many iterations if that were the case

  Live poliovirus vaccine continues to be used, and continues to cause occasional active cases and transmission.

Merriam Webster's old definition did not exclude therapeutic vaccines. But it did exclude vaccines prepared from viruses.[1] Probably you heard about diphtheria and tetanus vaccines before 2020. They are prepared from toxins. Other definitions did not restrict what a vaccine must contain.[2] [1] http://web.archive.org/web/20190118214500/https://www.merriam-webster.com/dictionary/virus http://web.archive.org/web/20190118214500/https://www.merria...

The word “vaccine” comes from the recognition that people could gain immunity against smallpox via infection with the less-deadly (and live) virus cowpox. https://en.m.wikipedia.org/wiki/Vaccinia https://en.m.wikipedia.org/wiki/Vaccinia The definition has never been constrained to dead pathogens.

This means that after injection, the viruses cause a harmless infection in the vaccinated person with very few, if any, symptoms before they are eliminated from the body. The person’s immune system fights the infection caused by these weakened viruses, and immunity (the body’s protection from the virus) develops.
