Of course he'a endorsing the vaccine, that was the entire goal of operation warp speed. To get out the vaccine asap.

Then again, just because he's endorsing it doesn't mean you should take it. You need to weigh the risks and the benefits. Are you at risk from complications due to covid? Are you frequently in contact with people who might be at risk? Then maybe you could consider getting it. If you are healthy and aren't worried about "killing grandma" then don't bother.
