Sanofi avoids EU fine as Commission accepts flu vaccine commitments
Sanofi avoided an EU fine by agreeing to stop disparaging rival flu vaccine Fluad (CSL Seqirus) in promotional materials. The EU investigated claims that Sanofi's Efluelda was safer, contradicting health recommendations. Sanofi committed to neutral messaging until 2030, with oversight. The case highlights EU scrutiny of promotional claims about competitors.
