It seems like viruses always tread a spectrum between infectivity and lethality. Does or could a virus exist which:

- has a 100% fatality rate, like rabies

- can keep the host alive long enough to spread and

- cannot be defeated by any prospective vaccine or can evolve fast enough to evade them?

Basically, airborne and human-to-human rabies, with no vaccine. Or vaccine resistant ebola, but even more lethal, infectious, and a longer incubation period.

Put more concisely, could a virus exist with the potential to wipe us out.

African Swine Fever is like that

It is very stable, so it does not need to keep the host alive for long. A corpse is still infectious like weeks laters

We are lucky that it can only infect swines
