Why didn't the FDA under the Biden administration demand & require any COVID mRNA technology based boosters e.g. bivalent booster (Wuhan strain plus BA.4 &.5 clades) to undergo HUMAN clinical trials?

Why? Why was the decision to grant EUA based on 8 mice (a rodent model) that I may add resulted in the mice actually getting sick from COVID; we used a rodent model where rodents got sick to get EUA?
