Dr. Jason Valentine, a physician at Diagnostic and Medical Clinic Infirmary Health in Mobile, recently posted a photo on his Facebook page showing him next to a sign that says, “Effective Oct. 1, 2021, Dr. Valentine will no longer see patients that are not vaccinated against COVID-19.”

NBC News has not verified the authenticity of the post, which is now private. Neither Valentine nor representatives at the medical clinic where he works could be reached for comment…

After sharing the picture on social media, Valentine wrote that three unvaccinated patients asked where they could get a vaccine, according to The Birmingham News.

“If they asked why, I told them COVID is a miserable way to die and I can’t watch them die like that,” Valentine wrote.
