Real science is never settled, and anyone who has certainty on such things is not qualified to discuss it.
Vaccines are not and were NEVER tested in combination? Yet they are routinely given that way, based only on the assumption that it’s fine.
IMO, it is risky and therefore foolish to get more than one vaccination every two weeks.

Side effects of the vaccines include heart inflammation, severe allergic shock, and nausea
A top official at the U.S. Food and Drug Administration is suggesting people space out vaccines for COVID-19, influenza, and respiratory syncytial (RSV).
"I have to be an honest person and say that some people are saying, 'well, could I get RSV, COVID, and the flu vaccine on the same day?' Yes, indeed, you could," Dr. Peter Marks, the official, said. "But honestly, I might not just because each of them can potentially make one a little fatigued or have a little bit of a fever. And I might just want to space them out a little bit."
He added later, "Oftentimes, we suggest if you want to minimize the chance of interactions and minimize confusing side effects from one with another, you wait about two weeks between the vaccines."
WIND: curious phrasing (“honest person”).
As for the COVID vaccine, getting it has no rational justification, excepting those at high risk for some reason and even then it’s not clear it has value given irresponsible non-testing and the current weak state of the COVID virus and its rapidly evolving nature.
