New study finds properly analyzing vaccination efficacy against variants may require new clinical studies
April 3, 2021 - 11:00 am

Researchers at the Lindsley F. Kimball Research Institute find that as variant strains emerge, we will need to reevaluate vaccine efficacy by testing the inhibition of viral infection in vivo rather than by quantifying the antibodies produced after in vitro exposure.

Reliable proof of immunity through vaccination may only come through reinfection challenge experiments or through longitudinal studies of postvaccination subjects.
