The patient's medical history, past medications, and concomitant medications were not reported. On 27-Oct-2025, the patient was vaccinated with Rotavirus Vaccine, Live, Oral, Pentavalent (ROTATEQ) oral solution at a dose of 2 mL (valid Lot Number: 2117047, Expiration date: 18-May-2026) for prophylaxis and with DTap-IPV-Hib-HepB (Vaxelis) Suspension for injection at a dose of 0.5 mL (valid Lot Number: U8335AA; Expiration date: 31-Oct-2027) for prophylaxis (routes of administration were not reported). It was reported that the vaccines were improperly stored before administration (Product storage error). No additional adverse event.
