The star, who recently launched a vegan shoe line Von D Shoes, received backlash online when she announced she wasn't planning to vaccinate her unborn child.
She said she was 'bombarded' with unsolicited advice - adding that there was 'some good and some questionable - unsolicited none the less'.
'A thoughtless post'
However, in a recent interview with the Los Angeles Times, Von D said: "When it comes to the vaccine issue, I was six months pregnant at the time, and I was still trying to figure out my birthing plan to have my son.
"And, at the time, I made a completely thoughtless post on my Instagram on whether or not I would vaccinate my son. And, because of it, people think I'm something that I'm not.
"But the truth is, I'm not an anti-vaxxer at all. I just made a mistake, and I was completely uninformed. It was stupid, and I really shouldn't have opened my big mouth on the subject."
The entrepreneur also spoke about veganism and how she pushed for her entire makeup line to be reformulated without using animal products.
"I'd been a vegetarian for a long time, but in 2011, when I became vegan, I felt I needed to be able to walk the walk and not just talk the talk," she said.
"We had to replace ingredients like beeswax and carmine [a red pigment made from crushed beetles]. I had no idea about any of that when we started."
