FDA Adds Guillain-Barré Syndrome Warning to GSK’s Shingles Vaccine
March 29, 2021
The FDA has issued a warning regarding GlaxoSmithKline’s (GSK) shingles vaccines, Shingrix, and said it must include a label warning about the risk of Guillain-Barré syndrome (GBS), a rare disorder.
“In a postmarketing observational study, an increased risk of GBS was observed during the 42 days following vaccination with Shingrix,” the FDA said.
The FDA approved Shingrix in October 2017 as a two-dose regimen for preventing shingles in adults age 50 years and older.
GBS affects the body’s immune system and damages nerve cells, causing muscle weakness and in some cases paralysis.
