You may believe it or not- I would be lying if I said I was totally confident one way or the other. You’re more likely to find this assumption in the Orthodox and I imagine Eastern Catholic Churches (that is that the Holy Mysteries absolutely may not cause deleterious effects.
An example from the life of St John Maximovitch:
“He served the Holy Mysteries to a woman dying of rabies, and immediately after doing so, she had a fit, foaming at the mouth, and spitting up the Holy Gifts. Knowing that the Holy Gifts cannot be thrown away, St. John immediately picked them up and swallowed them, himself, even though rabies is extremely contagious and routinely fatal. He said, “Nothing with happen; these are the Holy Gifts!” and he spoke the truth.”
