Trump advises parents on hepatitis B vaccine. Here's why doctors say he's wrong

Hepatitis B is a virus that attacks the liver and the disease has no cure. Since the U.S. started universally vaccinating newborns case rates have plummeted by 99%.

It's unusual for Presidents to give medical advise. But this week President Trump told parents to delay giving their kids a hep b shot until they turn 12. Doctors say this is bad and dangerous advice.
