I didn't make an assumption based on the headline, I made the assumption based on the statement at the end of the article, which I quoted in another comment.
Erin Clary, a health department spokesperson, said Thursday that while parents and legal guardians had sought out and paid Breen for her services, they weren’t the focus of the agency’s investigation.
It's still maybe an assumption - perhaps there were people who thought they were getting real vaccines, not a homeopathic alternative - but it's what the health department said.
I'm guessing you read that other comment after making this one, as you've since replied to that comment thread. So no worries.
I think the kind of people who would take homeopathic "vaccines" aren't the kind of people who would have taken precautions anyway, not unless forced to. You could maybe argue that they were endangering children by sending them to school, but really the danger would have been with the non-vaccinated child.
The only really significant new risk would be if a non-vaccinated homeopathic child was around a child who legitimately could not be vaccinated, but that's dependent on specific circumstances.
