That's not what they do when they test vaccines.
What they do is, they give one group the vaccine and one a placebo. Then they let them go about their daily lives and check to see if the 2 groups have different numbers of cases. You don't need to give them the virus, you just have to monitor to see if there is a difference in the amount of cases in each group.
