Johnson & Johnson released a statement that rare cases of the neurological disorder, Guillain-Barré syndrome have been reported following vaccination with the Janssen COVID-19 vaccine. Most occurred within 42 days after vaccination.
The statement continued:
While the chance of having this occur is very low, Johnson & Johnson has updated its COVID-19 Vaccine Factsheet to include important information about these rare cases and on the signs and symptoms of Guillain-Barré syndrome. Updates with this new information will be implemented in other regions of the world according to local regulatory procedures.
Any adverse event report about individuals receiving Johnson & Johnson’s single-shot COVID-19 vaccine, as well as our own assessment of the report, is shared with the U.S. Food and Drug Administration, the European Medicines Agency, the World Health Organization and other health authorities around the world where our vaccine is authorized.
We strongly support raising awareness of the signs and symptoms of rare events to ensure they can be quickly identified and effectively treated. Evidence has demonstrated that Johnson & Johnson’s single-shot COVID-19 vaccine offers protection against COVID-19 disease and prevents hospitalization and death, including in countries where viral variants are highly prevalent.
