Second Wave of CalSCOPE Antibody Survey Begins in Monterey County butterfly

Published: Oct 21, 2021

Monterey County residents could soon be receiving an invitation to participate in the second wave of CalScope, a study that will help public health professionals better understand how many people in California have antibodies to SARS-CoV-2, the virus that causes COVID-19.

The CalScope study invites randomly selected households in participating counties (including Alameda, El Dorado, Kern, Los Angeles, Monterey, San Diego, and Shasta) to complete an anonymous survey and a free, at-home COVID-19 antibody test using a finger-prick blood sample. The study will not ask for identifying information, such as name or date of birth. Mailed invitations were sent to 200,000 households in select counties beginning October 15, 2021. Participants receive incentives for completing different parts of the study.

Monterey County Health Department is working in collaboration with the California Department of Public Health, Stanford University School of Medicine, Enable Biosciences, Exa Health, and other county public health departments to conduct the CalScope study in three separate waves during 2021-2022.
