All 11 had obtained the Covid preventive 10-22 days earlier.
In Guillain-Barre syndrome (GBS), the physique’s immune system mistakenly assaults a part of its peripheral nervous system –the community of nerves positioned exterior of the mind and spinal wire.
The 2 research, printed within the journal Annals of Neurology on June 10, describe an uncommon variant of GBR characterised by outstanding facial weak spot.
The frequency of GBS from the areas the place the circumstances have been reported was estimated to be as much as 10 occasions higher than anticipated, the authors of the 2 research mentioned.
