EU Approval for Infant Indication
MenQuadfi is now approved for infants from six weeks of age against invasive meningococcal disease serogroups A, C, W, and Y, expanding the previous indication from 12 months and older.
-
Addresses High-Risk Population
Infants rank among the highest-risk groups for invasive meningococcal disease, which carries a case fatality rate of 10–15% and leaves up to 20% of survivors with permanent complications.
-
Supported by Robust Clinical Data
The approval rests on the pivotal MET58 study, which assessed immunogenicity, safety, and tolerability in over 6,000 infants across 11 countries.
-
Aligned with Routine Immunization Schedules
The approved 2+1 dosing schedule fits standard EU pediatric vaccination timelines, potentially easing adoption and boosting coverage.
Analysis · SNY · Life Sciences
The European Commission has cleared MenQuadfi for infants as young as six weeks, a label expansion that unlocks a highly vulnerable patient group. While the financial upside remains unquantified, the approval bolsters Sanofi's vaccines franchise and could generate incremental revenue. It follows a positive CHMP opinion in June and rests on strong immunogenicity data from the MET58 study.
