Okay, I got to ask. What the heck is this vaccine?

There are SO many crazy things. Do vaccines for coronaviruses exist? Can a vaccine really come out in a year? Can Trump's vaccine be trusted? Bill Gates's? What would Gates's have that Trump's wouldn't? Can vaccines permanently hurt you?

I'm hearing so much conflicting stuff. My mother won't come visit until she's got this vaccine. But my paranoid bells are ringing. But there are multiple vaccines. The worst stories are Gates trying to inject us with microchips or things that change our DNA. Is that reality, or science-fiction?

Hell, if I heard one of these medical companies was just trying to make a mountain of money off of the vaccines, I would breathe a sigh of relief. I'm more worried about them trying to permanently damage our health.

What's realistic and what isn't?
