An Arizona cardiologist told CNN in an interview that went online Monday that he doesn’t care if his refusal to vaccinate his kids gives other children grave, preventable diseases.

“I’m not going to sacrifice the well-being of my child. My child is pure,” Dr. Jack Wolfson said in the interview. “It’s not my responsibility to be protecting their child.”

Wolfson was responding to a public appeal for all parents to vaccinate their children from Arizona pediatrician Dr. Tim Sacks, whose leukemia-stricken daughter was exposed to measles after an unvaccinated American family introduced the disease into the greater population during a trip to Disneyland.

Wolfson was interviewed last week by television station KPNX as a source on the debate over vaccinations, calling himself “the paleo-cardiologist,” according to the report.

The doctor said that children should not avoid getting infections such as measels and mumps. “These are the rights of our children to get it,” he told KPNX.

Back on CNN, Wolfson dismissed his fellow doctor’s appeal to anti-vaxxers.

“As far as I’m concerned, it’s very likely that her leukemia is from vaccinations in the first place,” Wolfson said.

The CNN interviewer asked Wolfson repeatedly if he could live with himself if his unvaccinated child got other children, like Sacks’ daughter, fatally sick.

“I could live with myself easily. It’s an unfortunate thing that people die, but people die. And I’m not going to put my child at risk to save another child,” he said.
