I wonder what will happen after this first wave passes. Will people then need to get 2 shots each year, once for flu and once for corona and it's descendants?

I wonder what will happen after this first wave passes. Will people then need to get 2 shots each year, once for flu and once for corona and it's descendants? Can the two be handled with a single shot? I wonder also what will become of small population centers that manage to avoid the first wave. Will they suffer more greatly in the future, when the virus finally finds them?
