På WHO:s hemsida bland “frågor och svar”, kunde man i juni 2020 läsa att:
“Herd immunity is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection.”
Idag kan man dock se att WHO:s definition har ändrats och i stället står det:
Herd immunity against COVID-19 should be achieved by protecting people through vaccination, not by exposing them to the pathogen that causes the disease
