Flu Vax Giant Sanofi Defends Corner With $650m Protein Sciences Buy

In agreeing a $650m+ deal to acquire privately owned Protein Sciences, Sanofi is defending its market dominance in influenza vaccinations by adding an approved non-egg based product. The purchase may also help it defend its position in the section of the market targeting elderly patients, since its current trivalent offering is threatened by a rival quadrivalent product from Seqirus.
