FDA Warns of Possible Rare Association Between Johnson & Johnson Vaccine and Guillain-Barre Syndrome – WMUR

Read article - Michael Calderwood, associate professor of medicine, is quoted in a report linking a rare autoimmune disorder, Guillain-Barre Syndrome, with Johnson & Johnson’s COVID-19 vaccine. “Similar to what we were seeing back in April with the warnings on the Johnson & Johnson vaccine related to thrombosis and thrombocytopenia, the numbers are very small,” Calderwood said. “So, not to dismiss them, but we have to find the balance between what is a very rare side effect and what is the benefit from the vaccine itself.”
