In two separate articles in Annals of Neurology, doctors in India and England report cases of a rare neurological disorder called Guillain-Barré syndrome after people were vaccinated against COVID-19.
Both reports describe an unusual variant of Guillain-Barré syndrome characterized by significant facial weakness. Seven cases were reported from a regional medical center in Kerala, India, where approximately 1.2 million people were vaccinated with the AstraZeneca COVID-19 vaccine. Four cases were reported from Nottingham, England, in an area where approximately 700,000 people received the same vaccine. The eleven cases were of people who had received this vaccine between 10 and 22 days earlier.
It was estimated that the frequency of Guillain-Barré syndrome in these areas was up to 10 times higher than expected.
“If the link is causal, it could be due to a cross-reaction immune response to the SARS-CoV-2 tip protein and components of the peripheral immune system,” the authors of the England report wrote.
The authors of both articles emphasize this clinicians should be on the lookout for this rare neurological syndrome after COVID-19 vaccine administration.
