EMA takes Pfizer and Valneva Lyme disease vaccine into review

14 August 2026

The European Medicines Agency (EMA) has validated the marketing authorization application for PF-07307405, the six-valent Lyme disease vaccine candidate from US pharma major Pfizer (NYSE: PFE) and French vaccine specialist Valneva (Nasdaq: VALN), and has begun its assessment.
