Valneva SE has struggled to get its COVID-19 vaccine on the market, but efforts to get the first Lyme disease vaccine approved in years now appear firmly on track after partner Pfizer Inc. invested €90.5 million (US$94.9 million) in the project. New York-based Pfizer has been working with Saint-Herblain, France based Valneva on the Lyme disease vaccine since April 2020, when the big pharma bought into the development program for the vaccine candidate codenamed VLA-15 for $130 million.
