If your "normal times" scientific standards need to change for an emergency, then they were never appropriate to begin with. But here, I do think the scientific standards are OK. What should be changed in an emergency is not scientific rigor, but the amount of resource that we are willing to spend on the problem with an expectation of waste. With that mindset, throwing money at the problem to fund trials that address a wide range of questions (e.g., 1 vs 2 doses of Pfizer/Moderna, 2 vs 4 vs 6 weeks for booster timing, etc) would have been the way to go.
