CDC: Guillain-Barre Syndrome more common with RSV vaccine in older adults

  • / Updated:
  • Staff Report 

The CDC reported Thursday that cases of Guillain-Barre syndrome are “more common than expected” in older adults who received the new RSV vaccines. Despite this, officials say the benefits of the shots still outweigh the risks.


The CDC and FDA are evaluating the risks but have not changed their recommendation. They advise people 60 and older to discuss the vaccine with their doctor before deciding. Over 10 million older adults have received Pfizer or GSK’s single-dose RSV shots since August to protect against the respiratory virus, which can be dangerous for infants and seniors.

Health officials found about two cases of Guillain-Barre syndrome per million vaccine recipients within three weeks of vaccination. The new report detailed 28 cases, translating to 1.5 cases per million for GSK’s vaccine and five cases per million for Pfizer’s. Most people recover from Guillain-Barre, though some may have lasting nerve damage.
