Steven Brandenburg, 46, was sentenced Tuesday after pleading guilty back in February to two felony counts of attempting to tamper with a consumer product. He had faced up to 20 years in prison, according to a statement from the Department of Justice. Brandenburg was arrested on Dec. 31, 2020, after losing his job at Aurora Medical Center in Grafton. He was fired after leaving 57 vials of the Moderna COVID-19 vaccine out over two nights. Wisconsin Hospital Worker Fired After 'Intentionally' Spoiling 500 Doses of Coronavirus Vaccine All of the available COVID-19 vaccines require refrigeration. Brandenburg believed the inoculations were unsafe, according to a probable cause statement. Brandenburg told investigators told he thought the vaccine was capable of altering recipients' DNA. There is no scientific basis for such a belief, and multiple large-scale studies have shown that vaccines are safe. He also told detectives he purposely left the doses out, hoping to taint them. He returned the vials to the hospital's refrigerators in the mornings. Wisc.
