the baby was diagnosed with RSV when she was 9 months old; the baby was diagnosed with RSV when she was 9 months old; This is a spontaneous report received from a Pharmacist. A 9-month-old female patient received rsv vaccine prot.subunit pref 2v (ABRYSVO), in 2023 as dose number unknown, single (Batch/Lot number: unknown) other for maternal immunisation. The patient's relevant medical history and concomitant medications were not reported. The following information was reported: RESPIRATORY SYNCYTIAL VIRUS INFECTION (medically significant), DRUG INEFFECTIVE (medically significant), outcome "recovered" and all described as "the baby was diagnosed with RSV when she was 9 months old". It was unknown if therapeutic measures were taken as a result of respiratory syncytial virus infection, drug ineffective. The information on the batch/lot number for rsv vaccine prot.subunit pref 2v will be requested and submitted if and when received.; Sender's Comments: The 9-month-old infant received one dose of ABRYSVO for maternal immunization then was diagnosed with RSV; a lack of efficacy with the vaccine ABRYSVO therefore cannot be completely excluded. The patient's predispositions such as young age and underlying conditions may also contribute to suboptimal response after vaccination.
