I agree that there have been some indications that antibodies may not be long-lasting. But other indications have been better... and antibodies are not the only form of immunity. The so-called T-cell mediated immunity possibility looks stronger. And even some hint that a significant number of people may benefit from a T-cell response from a prior coronavirus (cold) infection.

I'm unwilling to get too pessimistic on the topic. With 13 million confirmed infections worldwide... I would expect to have heard of tens of thousands of such stories if reinfection were a significant thread (rather than a comparatively rare possibility).
