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.

What we can learn from the 1918 Flu Pandemic as the Omicron variant spreads

Historically, most pandemics end within 2 to 3 years as the virus mutates into a less virulent pathogen and the population builds up immunity. This is what happened to the influenza strain behind the 1918 flu pandemic.
