Not all antibody tests identify the same antibodies. Through an innovative trial design, researchers were able to demonstrate the impact of REGEN-COV in high-risk household transmission settings (month 1, both pre- and post-exposure prophylaxis), as well as after the immediate risk of household infection had subsided (months 2-8, pre-exposure prophylaxis), when most infections were presumably acquired in the broader community.
