In a finding that reinforces the safety of COVID vaccines, a new study shows that while the shots don’t raise the risk of rare neurological problems, COVID-19 infection might. The researchers focused on four immune-related neurological disorders: Bell’s palsy (facial weakness), encephalomyelitis (inflammation of the brain and spinal cord), Guillain-Barré syndrome (a nerve condition), and…  read on >  read on >
