There are at least two vaccines in trials. One in Washington state started a week or so ago. It’s being tried for both safety and effectiveness. Hopefully one or more will work. However it won’t be soon no matter what. There’s a lot to learn yet.
How do you test a vaccine? If it's a cure give it to people and see if it cures them. If it's a vaccine and you give it to healthy people you can't very well deliberately expose them to the virus. At least not in this country.
