This sounds like a terrible way to test the vaccine’s efficacy.
A better test would be to have all the participants walk through a minefield of people with the virus. Breath in all that infected air.

This is normally considered ethical only when an effective cure (e.g. antibiotics) is available. Even so, there are plans to conduct such a trial in the UK, and there's no shortage of volunteers. We'll see if they get approval.
