Public Health Experts Urge Caution on China's COVID-19 Vaccines Forest Cong WASHINGTON - China said on Friday that it had joined a global COVID-19 vaccine distribution plan backed by the World Health Organization, becoming the biggest economy to date to pledge support to distribute the shots fairly. Meanwhile, the country is holding separate talks with the WHO to have its COVID-19 vaccines assessed, a step toward making them available for international use. Public health experts welcome the Chinese move, yet caution potential safety concerns. They are calling on China to publish all its clinical trial data to ensure transparency and gain public trust, saying rushing out a vaccine without adequate efficacy and safety testing is a recipe for disaster. .
