If the vaccine was randomly administered among the study population, I'd buy this as the simple explanation.

Not sure it follows so cleanly with the actual study setup

Love this, thanks for building it, way faster way to explore options than what I'm used to!

Could be worth adding some kind of 'only show available domains' option

(edit: realizing this may require a rework of how the underlying availability checking process works, but could be worthwhile)
