LOS ANGELES, Nov. 24 (Xinhua) -- COVID-19 vaccine uptake in the United States is lower than expected, with only 14 percent of U.S. adults had gotten an updated COVID-19 vaccine through Nov. 4, according to the latest information of the U.S. Centers for Disease Control and Prevention (CDC).
COVID-19 is still an important cause of hospitalization and death, especially for older adults and people with certain underlying medical conditions, said CDC.
