evidence: New RSV shots tied to rare nervous system disorder — should you worry? [...] The new RSV vaccines approved for older adults may be linked to a slightly increased risk of a rare neurological condition, a recent analysis finds. [...] Health officials still recommend getting the RSV vaccines because the risk of developing Guillain-Barré is so low compared with the risk posed by an RSV infection, said Dr. Simon Drysdale, a pediatric infectious disease specialist in the Oxford Vaccine Group. For adults over 60 living in high-income countries, their risk of dying from RSV if they're hospitalized with the infection is 7%, Drysdale said, citing 2023 research published in the journal Influenza and Other Respiratory Viruses.
