Great Expectations of COVID-19 Herd Immunity

mBio, 2022
There is a common preconception that reaching an estimated herd immunity threshold through vaccination will end the COVID-19 pandemic. However, the mathematical models underpinning this estimate make numerous assumptions that may not be met in the real ...

Elementi metodologici per una riflessione sui dati dell’epidemia di sars-cov-2

Giornale di Clinica Nefrologia e Dialisi, 2020
Findings of the seroprevalence survey conducted by Istat between May 25 and July 15 2020, on a sample of 64,660 people, show that only 2.5% of Italian people developed antibodies to SARS-CoV-2, a prevalence very far from the hypothesis of achieving herd ...

R0 of COVID-19 and its impact on vaccination coverage: compared with previous outbreaks

Human Vaccines & Immunotherapeutics, 2021
Background: Vaccination has been known to reduce morbidity and mortality of infectious diseases since the emergence of the 1st vaccine in the 18th century. That’s why global efforts are directed toward finding a vaccine for COVID-19 in order to eliminate

"Herd Immunity": A Rough Guide [PDF]

Clinical Infectious Diseases, 2011
The term "herd immunity" is widely used but carries a variety of meanings. Some authors use it to describe the proportion immune among individuals in a population. Others use it with reference to a particular threshold proportion of immune individuals that should lead to a decline in incidence of infection.

Digital Herd Immunity and COVID-19 [PDF]

Physical Biology, 2020
A population can be immune to epidemics even if not all of its individual members are immune to the disease, just as long as sufficiently many are immune—this is the traditional notion of herd immunity. In the smartphone era a population can be immune to epidemics even if not a single one of its members is immune to

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
