Rare Neurological Disorder Linked to COVID-19 Vaccination, Research Suggests

Rare Neurological Disorder Linked to COVID-19 Vaccination, Research Suggests

A recently published review in Vaccines shows COVID-19 vaccines may trigger Parsonage–Turner syndrome—a condition that causes intense pain and muscle atrophy.

A new systematic review suggests COVID-19 vaccination could trigger a rare neurological disorder that primarily affects the nerves outside the central nervous system, causing pain, muscle atrophy, and, in some cases, paralysis.

In a March 14 paper published in Vaccines, researchers found Parsonage–Turner syndrome (PTS) may occur after all COVID-19 vaccine types and can recur with additional doses of similar or unrelated vaccines.

To determine whether a relationship exists between COVID-19 vaccines and the development of PTS, researchers searched LitCOVID and the World Health Organization’s COVID-19 databases through Jan. 25. They found 59 cases of PTS reported in the literature following COVID-19 vaccination. Of those 59 cases, 36 patients (61 percent) received an mRNA vaccine, and 18 patients (30 percent) received a viral vector vaccine.
