They take the virus, add a blocking gene and hope that by giving you the virus you build immunity.
That is how they solved the flu.. trillions of dollars later a hundred years later. We are no smarter than we were during the 1918 pandemic.

Covid-19 vaccines may have potentially unpleasant side effects
Early data suggest several of the coronavirus vaccines may cause people to feel crummy for a few days. And then they'll need a second dose.The vaccine, and likely most others, will require two doses to work, injections that must be given weeks apart, company protocols show.
Scientists anticipate that the shots will cause enervating flu-like side effects — including sore arms, muscle aches and fever — that could last days and temporarily sideline some people from work or school.
And even if a vaccine proves 90 percent effective, the rate Pfizer touted for its product, 1 in 10 recipients would still be vulnerable.
That means, at least in the short term, as population-level immunity grows, people can't stop social distancing and throw away their masks.
