@cryptoinsider9305 I as well do not know what you mean.
The virus has only one single purpose: To multiply itself! It does not go to work, it does not go clubbing, it only wants to find other cells, rape them and multiply.
For achieving that goal most effectively, it will try rolling through different mutations. It can develop into something more aggressive, trying if it can overcome the immune system even better ... including a vaccinated immune system. On the other hand, if it is too aggressive and all hosts are getting killed, that can neither be in the interest of the virus.
And therefore, if an aggressive variant is not successful, it may mutate to something that is acceptable for the host. Just like what the flu virus is. That is why we need vaccines. At one point of time all of us will get infected, yep, everybody will get infected. Better your immune system can fight the infection then.
