Placebo trials are the gold standard for conditions that do not have an existing treatment.
The gold standard for evaluating new treatments is a double blind study with both the old and new treatment.
When there is an existing treatment, a placebo based double blind study is simply impossible. There is no way to get it past the ethics review board, because the study would leave half the participants completely unprotected.
Even if for some reason a placebo trial was approved, guess what? If it successful, the next step is, you guessed it, test the new treatment against the old treatment to see if it is even worthwhile, i.e., a double blind study with both the old and new treatments.
A placebo trial tell you if the treatment is better than nothing, but the only question worth asking is, is it better than what we have now?
In short, the entire "Must be a placebo trial" is just a thinly veiled anti-vaxxer effort to make new vaccines impossible to approve in the USA. Not only do the anti-vaxxers want to skip the vaccines, they want to make it impossible for anyone else to get them either.
