The U.S. Centers for Disease Control and Prevention (CDC) plans a nationwide study of up to 325,000 people to track how the new coronavirus is spreading across the country into next year and beyond.

To gain insights into how antibodies evolve over time, this study will remain in the field for over 18 months said CDC spokeswoman Kristen Nordlund. Learn More
