Whilst no general system of immunity from criminal prosecution for public employees exists, immunity may be available under certain circumstances however.
Our finding of limited overall household transmission for a novel influenza virus against which little pre-existing immunity exists could be due to the fact that antiviral drugs were given to all household members upon detection of infection.
Innate immunity existed before adaptive immunity.
The animal models of poxvirus infection have been used to evaluate immunity, but no generally established laboratory surrogate exists for immunity to smallpox virus itself.
A known sex bias exists in immunity to T. muris infection [ 16, 17] whereby female mice are known to mount a stronger Th2 response to infection and are thus more resistant.
Observers of this outbreak reported that temporary immunity existed for 5 10 months after an episode of dengue; after several attacks, more lasting immunity existed.
If a natural recycling sequence ever existed, present population immunity precludes H1 as a pandemic candidate for years to come.
During this season, the pre-existed immunity in the general population was also limited due to a reassortment event in the A(H3N2) influenza virus [ 28, 29].
If functional breast mucosal immunity exists, then quantitative profiles of immune cells in breast tissue may be predictive of breast cancer risk.
It could be that, in any untreated cancer, because of positive immune selection, whatever immunity exists may usually be near the stimulatory maximum, around "c" on the IRC.
Different investigations defining HER-2/neu-specific immunity in patients with cancer indicate that high levels of both T cell and antibody immunity exists in some patients, even if it is low or lacking in the majority of them (Disis et al, 1994; Fisk et al, 1995; Peoples et al, 1995).
