Just a small akshually :
Viruses cant be dead or alive because the have no metabolism anyway so most
(modern) vaccines work by extracting their mrna or the lipids on their surface and injecting that. Injecting a small portion of whole viruses my still infect you. Fyi
Edit: ok I talked some garbage here: while viruses do not have a metabolism and thereby are, by the definition of some, not alive, there is apparently a way to make vaccines by destroying the genome of the virus via heat or chemicals and using the “shells” to make vaccines…

mRNA vaccines are, of course, just the absolute tits - but they’re a tiny proportion of modern vaccines and the very first ones are one a few years old, created to treat COVID. But yeah, 100%, we don’t use the virus in the vaccine! Even the first ever vaccine was (as you will know) not created from the disease it was meant to treat, but from one similar enough that it gave protection to the other. And smallpox doesn’t exist any more so, well, that worked out pretty well didn’t it. You don’t give someone the virus to stop them getting that virus, but you might well give them a virus, in an attenuated form of the target
