STAT+: European antitrust regulators probe Sanofi for allegedly disparaging a rival flu vaccine

The European Commission is investigating Sanofi for allegedly violating antitrust rules by running a misleading campaign that disparages CSL Seqirus's Fluad vaccine, portraying it as inferior to Sanofi's Efluelda vaccine. The campaign targeted healthcare professionals in Germany and France, where Sanofi holds a dominant market position, and contradicted national vaccine recommendations in several EU member states.
