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…
