Actually, these were pretty massive clinical trials - far larger than the "normal" trials by more than a tenfold. mRNA trials have been going on for many years, so that, combined with the huge amount of people in these trials, is certainly equivalent to a "normal" trial.
Think of this as being the same as the seasonal flu vaccine - the basic technology has been around for years and it is just an annual update.
