Researchers have found that COVID-19 vaccination is linked to an elevated risk of facial palsy, with the risk particularly high within 28 days of taking the shot.
Facial palsy, also known as Bell's palsy, leads to temporary weakness or paralysis of the facial muscles, resulting in drooping on one side of the face and difficulty making facial expressions. Although the exact cause of the condition is not known, experts believe that certain viral infections, autoimmune mechanisms, or vaccination can be potential triggers.
