Virus zero days analogy with biological viruses

Hi! Had a question. when we talk about bugs (known bugs and unknown bugs) can we have analogy with
viruses that human beings’ bodies face ? like Coronavirus . So, Coronavirus (no patch, zero days) because we don’t have a vaccine (patch) yet ? Is this true ?

Depends on who you are talking to, the nation state/s/APT that probably released this virus have so much power and influence on all aspects of society, the ‘patch’ they release will come with strings attached, or have some kind of ‘backdoor’ in terms of a health cost to yourself

There are plenty of anti-virals out there, I certainly wouldn’t be running towards a vaccine without being 100% certain it was safe, and knowing exactly whats in it
