Viruses don't die!... they are not even considered as 'living beings'! technically speaking.. Yep!.. that's right.

Viruses are just tiny bits of DNA OR RNA packed in a proteic Capside. This is why they need living cells (of whatever host they can infect) to spread/propagate....

The only way out is immunization, and that takes time to develop after first contact, and yes many die in that process; this is what we refer to in BioSciences as the 'Natural Selection' acting on populations(/doing its thing in the wild.)

Vaccines are Man's ingenuity at speeding up that process(/acquired immunity) without being in prior contact with the fully functional virus, thus saving lives.

Two ways a virus can be neutralized:

• when the host is fully immunized; that makes the virus an easy target for human's anti-viral defences (which is a specialized case of human cellular immunity, with lymphocyte T4/T8 at its heart.)
  
• when the virus loses that critical key that allows it to infect that particular kind of cells in that particular kind of hosts; the same key that since it has acquired it (following a mutation event) put it into our spotlight as a life-threatening agent.
  

This drama is really just the ages-long process of 'Life' in action, but this time under the Megaphones of a 'globalized World Order'. I know this expression is cliché, but describes best the situation as I witness it.

Anyway, I thought a bit of trivial biology bullet-points won't hurt anyone here :-)

thanks for the correction . i really appreciate it . also your explanation is great
so i change it now to hopefully more people get immunized to the virus so the effect can be much lowered
