mRNA COVID-19 Vaccines Not Tied to Increases in Guillain-Barré Syndrome

MONDAY, Feb. 6, 2023 (HealthDay News) -- Ad26.COV2.S (Janssen) vaccination is associated with an increased risk for Guillain-Barré syndrome (GBS), but no similar increased risk was seen for mRNA COVID-19 vaccines, according to a study published online Feb. 1 in JAMA Network Open.

Winston E. Abara, M.D., from the Centers for Disease Control and Prevention in Atlanta, and colleagues evaluated GBS reports to the Vaccine Adverse Event Reporting System (VAERS) and compared reporting patterns within 21 and 42 days after vaccination with the Ad26.COV2.S, BNT162b2 (Pfizer-BioNTech), and mRNA-1273 (Moderna) COVID-19 vaccines.
