NEW: President Trump has been saying his immunity makes him feel like Superman. But the treatments he got may have prevented his body from making antibodies of his own, leaving him more susceptible in a few weeks than the average Covid-19 survivor. 1/x https://www.nytimes.com/2020/10/14/health/trump-may-be-immune-to-the-coronavirus-but-for-how-long.html

The Regeneron antibodies have a half life of 21 and 25 days. meaning that by Oct 23, their levels in his body will fall by half and then keep declining. 2/x

Mr. Trump did not have antibodies of his own when he got the Regeneron cocktail. The cocktail suppresses virus + dexamethasone tamps down immune system, so there's a good chance he didn't make any antibodies. 3/x

And that means, unless Mr. Trump keeps taking the cocktail, when those drugs break down, he will have no protection from the virus. 4/x

Ironically, taking all of these powerful drugs so early in his illness may in fact have left him unprotected long term.
