Should someone not take the COVID vaccine because of remedy concerns?

I know someone who was told by her homeopathist not to take the COVID vaccine because it would interfere with her remedy.

I'm concerned about this because given this person's advanced age, they have a sizable chance of dying from COVID. It seems unwise to risk one's life because of this concern with a remedy.

In addition, it seems to me that any interference with the remedy can be solved by, well, another remedy. After all, we all take vaccines from the time we're kids (and booster shots every few years) and homeopathists don't seem to be opposed to that.

Are there homeopathists out there (or others) who think this is not a concern that should prevent an elderly homeopathy patient from getting a COVID vaccine? Thanks in advance!
