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.
Confirmed Omicron cases, deaths, and admissions
France, Israel, Denmark, and Ireland have the highest cases per capita of Omicron in the world. This shows what happens with massive surges of virus spread, even ones with 60-70% less severity.
