Chinese vaccine developers target delta variant

China Daily  

Doses of the Chinese Sinopharm vaccine against the coronavirus disease are seen. A handful of Chinese COVID-19 vaccine developers said recently that they have obtained the highly contagious delta variant and geared up to develop vaccines targeting the new strain, which has spread to more than 130 countries and regions. Last week, Yang Xiaoming, president of Sinopharm's China National Biotech Group, said the company had accelerated research into new vaccines designed to tackle variants, assessing their efficacy and safety in preclinical studies. "We are exploring new vaccines targeting the delta strain based on our established and mature technologies, procedures and standards that have been applied to the first-generation dose," she said. "It will take longer if the top drug regulator requires completion of all three phases of human trials," he said, adding that drug regulators will take into consideration the fact that some new vaccines only replace the old strain with a new one without altering their core production technologies.
