BEIJING, Sept. 19 (Xinhua) — A spokesman for the U.S. Centers for Disease Control and Prevention (CDC) said Monday that it plans to conduct a study in the U.S. involving up to 325,000 people to track how the new coronavirus will spread next year and beyond.
The study, which is expected to be launched in June or July, will test antibodies produced by the immune system against the new coronavirus in blood donors in 25 major U.S. cities. The researchers plan to publish the results on a rolling basis.
Antibody studies, also known as serum-positive studies, are thought to be critical to understanding where the virus is spreading and can help guide decisions about the restrictive measures needed to control the spread of the virus.
The CDC study may also help scientists better understand whether the immune response to the new coronavirus weakens over time.
