Table 4 Modifiers of the paediatric virome

Modifier	Key impact on virome	Long-term consequence
Antibiotics	SOS response and prophage induction	Bacterial instability; expansion of ARGs
Breast milk	Transfer of sIgA and maternal phages	Enhanced barrier protection; regulated assembly
Oral vaccines	Competition with resident viruses	Potential for altered vaccine “take” and immune priming
NICU Stay	Reduced diversity; hospital signatures	Increased risk of NEC and delayed immune maturation

NICU: Neonatal intensive care unit; ARGs: Antibiotic-resistance genes; NEC: Necrotizing enterocolitis; SIgA: Secretory IgA.
