Despite the start of the corona vaccination campaigns in numerous countries, the World Health Organization (WHO) does not expect that this year, in individual countries, extensive protection against the virus will be achieved through so-called herd immunity. “We will not reach any levels of population or herd immunity in 2021,” said WHO chief scientist Soumya Swaminathan in a virtual press briefing on Monday.
Herd immunity is when so many people in a population are immunized against a pathogen that it can only spread a little and thus the non-vaccinated people are largely protected from it.
