SAN FRANCISCO (KRON) — San Francisco’s city attorney is investigating a local pediatrician for allegedly providing fake medical exemptions to families so they could avoid vaccinating their kids. 

The office of San Francisco City Attorney Dennis Herrera issued a subpoena today for the doctor’s medical records as part of its investigation as to whether Dr. Kenneth Stoller provided vaccine exemptions to children who shouldn’t have qualified. 

A California law that took effect in 2016 requires that any student attending private or public school in the state has to be vaccinated unless they’re eligible for a medical exemption — something that’s normally provided by a child’s doctor.

In this case, the city attorney is alleging Stoller’s patients were able to forego vaccinations because of false exemptions he provided. 

The attorney’s office says the number of medical exemptions provided by doctors has significantly increased since the law went into effect in 2016, despite actual medical exemptions being pretty rare.

Stoller reportedly based his medical exemptions off of two 30-minute visits with his patients and DNA testing through the online genetic service 23andMe. 

The genetic testing company says on its website that the information it provides should not be used to make medical decisions. 

The city attorney’s office would not disclose how it became aware of the allegations, nor would it say how many medical exemptions the doctor may have provided. 

Stoller now has 15 days to respond to the city’s subpeona.
