"The complaint referred to his treatment of a child known as J.G., treated by Dr. Sears from the age of two on, during 2014-2015. The allegations included negligent treatment of the child and poor record keeping."

"What appears to have happened is that J.G.’s mother claimed that her son experienced reactions after his vaccines, and without obtaining the child’s prior records, Dr. Sears translated them into more severe reactions than described and gave an exemption based on that."...
"In other words, Dr. Sears appeared to have written a letter exempting the child from all future vaccines, a letter that at best was not well-founded, without any real investigation into the fact."

Sears was also disciplined for failing to give a young child a neurological exam after he complained of a headache (his father reportedly had hit the child with a hammer), and for failing to keep proper medical records.

The medical board has required Sears to take a 40-hour medical course for every year of his three-year probation to repair any deficiencies in his practice, to take a medical ethics course and to have a monitor supervise his practice. These were serious charges and penalties that went beyond Sears' well-known advocacy for a non-evidence based "alternative" vaccine schedule.'

He is considered an anti vaxxer, and does not think herd immunity is a thing.
