This paper offers projections of future transmission dynamics for SARS-CoV-2 in an SEIRS model with demographics and waning immunity. In a stylized optimal control setting calibrated to the United States, we show that disease is endemic steady state its are characterized by damped oscillations. The magnitude oscillations depends on how fast immunity wanes. social distancing policy both curbs pe...

Whereas the usual notions of immunity -- e.g., immunity, hyperimmunity, etc. are associated with Cohen genericity, canonical as introduced by Beros, Khan and Kjos-Hanssen, is instead Mathias genericity. Specifically, every generic canonically immune no 2-generic computes a set.

Plant proteins with domains rich in leucine repeats play important roles detecting pathogens and triggering defense reactions, both at the cellular surface for pattern-triggered immunity cell to ensure effector-triggered immunity. As intracellular parasites, viruses are mostly detected intracellularly by a nucleotide binding site leucine-rich but receptor-like kinases repeats, known localize su...

BACKGROUND This study was undertaken to determine whether rubella immunity infers measles immunity in pregnant women. METHODS Stored serum samples were obtained from the Iowa State Hygienic Laboratory for evaluation of rubella and measles immunities with IgG enzyme-linked immunosorbent assay. RESULTS Nine hundred serum samples were obtained for testing. The average age of the women at the t...

Adaptive immunity towards tuberculosis (TB) has been extensively studied for many years. In addition, in recent years the profound contribution of innate immunity to host defence against this disease has become evident. The discovery of pattern recognition receptors, which allow innate immunity to tailor its response to different infectious agents, has challenged the view that this arm of immun...
