Mr. Weidong Yin, Chairman, President and CEO of Sinovac, commented, “Now that SINOVAC has received WHO prequalification for our varicella vaccine, we can provide a new weapon for prevention and control of infectious diseases globally. In the future, we will continue to work on more clinical trials, registrations and approvals for vaccines worldwide, to offer the world high-quality vaccines and ensure the accessibility and affordability of these public goods.”
