Xiamen Innovax’s bivalent HPV vaccine has won WHO prequalification, PATH announced Tuesday.
The quality mark allows UNICEF and other international agencies to buy the shot—and breaks Merck’s and GSK’s hold over Gavi supply.
PATH—which provided technical assistance to China-based Innovax during the WHO review process—is also sponsoring a Phase 3 trial (underway in Bangladesh and Ghana) to evaluate regimens of the shot with fewer doses.
