The vaccine strain was identified in cerebrospinal fluid by reverse transcription-PCR and sequencing. This case may illustrate potential blind spots in current vaccine safety surveillance, which often rely on short monitoring windows and passive reporting. It suggests that consideration of longer surveillance periods, improved clinician awareness of delayed neurological complications and greater diagnostic vigilance may be warranted. The patient recovered fully without sequelae.<\/jats:p>","DOI":"10.1136\/bcr-2025-271248","type":"journal-article","created":{"date-parts":[[2026,2,15]],"date-time":"2026-02-15T19:15:23Z","timestamp":1771182923000},"page":"e271248","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Delayed neurological events after mumps vaccination: implications for surveillance and clinical recognition"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4855-1787","authenticated-orcid":false,"given":"Masazumi","family":"Miyahara","sequence":"first","affiliation":[{"name":"Pediatrics, Okanami General Hospital, Iga, Mie, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyoko","family":"Osaki","sequence":"additional","affiliation":[{"name":"Pediatrics, Okanami General Hospital, Iga, Mie, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manami","family":"Negoro","sequence":"additional","affiliation":[{"name":"Pediatrics, National Hospital Organization Mie Hospital, Tsu, Mie, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeru","family":"Suga","sequence":"additional","affiliation":[{"name":"Pediatrics, National Hospital Organization Mie Hospital, Tsu, Mie, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,2,15]]},"reference":[{"key":"2026021511151362000_19.2.e271248.1","unstructured":"World Health Organization .
