I went in for a quick blood draw for the clinical trial and found they switched things up. Before, the real drug was the new formulation of Evusheld, and the placebo was the old-school Evusheld (the one useless against omicron), so they could show the increase in effectiveness.
Evidently the government got involved and changed up the rules. It's now a cage match between the new drug and salt water, at least for me.
It doesn't matter anyway, because I know that just the act of taking even a placebo is beneficial, so just knowing you got salt water skews the results somewhat.
I suppose this is the change in pace you get when you are battling a mutating virus.
