Valneva Reports 95% Seroresponse Four Years After Single Shot of Chikungunya Vaccine IXCHIQ®
Long-lasting antibody persistence was comparable in older (65+) and younger adultsLong-term antibody persistence is a key competitive advantage for a vaccine targeting unpredictable outbreak diseases like chikungunya Saint-Herblain (France), September 30, 2025 – Valneva SE (Nasdaq: VALN; Euronext Paris: VLA), a specialty vaccine company, today reported positive antibody persistence data four years after vaccination with a single dose of its chikungunya vaccine IXCHIQ®.
