A UK study by University College London has confirmed “small but significant” cases of the serious Guillain-Barre syndrome (GBS), a rare neurological disorder associated with the AstraZeneca vaccine for COVID-19.
The researchers speculate that “the majority or all” of the 121 UK cases of GBS (pdf) in March to April 2021 were associated with first doses of the AstraZeneca vaccine administered in January.
