Your Blood May Predict How Well a Vaccine Will Work

Scientists at Arizona State University analyzed 8,687 blood samples before and after COVID-19 vaccination from 4,089 participants and measured antibodies to 185 antigens. Using deep learning, they identified 'sentinel' antibodies that can predict a weak or strong response to vaccination before the shot.

• Studied 8,687 blood samples and antibodies to 185 antigens
• 4,089 participants, including immunocompromised individuals
• 5–6% of healthy participants had weak response to vaccine
• Method based on AI analysis of antibody 'fingerprint' in blood
