JPR reviews the science, or lack thereof, behind the claims that the flu shot reduces severity of disease, hospitalization, and mortality, and shows you how to quickly prove such science doesn't exist to those around do. He also reviews what flu shot claims ARE valid, from a scientific viewpoint. And given there's no evidence the vaccine reduces person to person transmission (and yes, he shows you how to prove that too), mandating this vaccine for school or employment isn't justified.
