Sanofi confident for 2019 despite third-quarter sales slip

PARIS (Reuters) - Sanofi expressed confidence for the fourth quarter and confirmed its full-year objectives on Thursday after posting lower third-quarter sales, hit by a fall in revenue at its primary care business and a drop in vaccines.Sales at the French drugmaker's vaccines unit were down 9.8% at constant exchange rates as a result of a decision by the World Health Organisation this year to delay its choice of recommended compositions of influenza virus vaccines.Chief Financial Officer..
