I think this is a slightly-too-bleak-for-the-evidence take, because it's not clear how long immune defense persists. COVID antibodies tend to go away kind of quickly, but there are (so I hear) other mechanisms of defense which may persist longer. Things could of course be much worse - it's possible that the COVID molecule is somehow unusually well situated for immune escape and length of immunity won't matter that much; those of us in countries that can afford it will get our semi-annual microchip infusion with the latest flavors.
