Not everyone survives. That's life. You can't expect society to shut down to protect the tiny percentage of people who can't be vaccinated or are immunocompromised. That's never been an expectation of society before so why would it be one now?
It has been. The reason these people survive is because vaccines are required for everyone as a child (in the US). Without that they would catch mumps, measles, polio, etc.
And wearing a mask inside public spaces is not shutting down society.
