Recently approved vaccines for respiratory syncytial virus (RSV) for older adults may be linked to a rare nervous system disorder that causes the body’s immune system to attack its own nerves.

In a Feb. 29 meeting of the Advisory Committee on Immunization Practices, health officials presented data that appear to show a slightly elevated rate of Guillain-Barré syndrome (GBS) among people who received RSV vaccines by Pfizer and GlaxoSmithKline (GSK).
