Meaning of inmunidad de rebaño by furoya

Also called "group immunity" or "collective immunity" is a term proposed by microbiologists Graham Selby Wilson and William Whiteman Carlton Topley in 1923, suggesting that in an epidemic case the study of individual immunity should be separated from that of the collective immunity, since when a sufficient amount of resistant population appears these form a barrier to the virus that does not reach those who are not vaccinated or lack defenses. The number is a statistical calculation (usually obtained past the epidemic and serves for the next) that takes into account too many variables to anticipate the sufficient percentage that can serve as indirect protection, especially in new diseases. The original English name is herd immunity. See R 8320; r0 , R 8337; re, pandemic, covid-19.
