via Pfizer is taking its Valneva-partnered Lyme disease vaccine into phase 3. With midphase data supporting a three-dose series, the allies plan to kick off a phase 3 clinical trial of the regimen in the third quarter.

At that time, Valneva had already started two phase 2 clinical trials of the vaccine candidate. Pfizer and Valneva initiated a third midphase trial to compare two- and three-dose VLA15 regimens last year, leading to the generation of the data that has now persuaded the partners to move into phase 3.
