In summary, in this study of more than 40,000 LAIV recipients 5–17 years of age, rates of MAEs and SAEs were compared between LAIV-vaccinated individuals and multiple nonrandomized controls. SAEs and hospitalizations after vaccination with LAIV were uncommon, and no pattern of MAEs was found to occur at higher rates than control groups. The results of this study are consistent with preapproval click here studies [3], [13] and [14] and with reports to the Vaccine Adverse Events Reporting System in the years after the initial approval of
LAIV [12], which demonstrated no significant adverse outcomes after receipt of LAIV by eligible individuals 5–17 years of age. A similar study is currently underway in children 2–4 years of age.

“T cells are important mediators of the adaptive immune response against infections caused by intracellular microorganisms, including the digenetic intracellular protozoan parasite Trypanosoma cruzi, the causative agent of Chagas disease (American trypanosomiasis). Genetic deficiency or specific treatments leading to the depletion of CD4+ or CD8+ T cells critically impairs the acquired immunity observed during experimental mouse infection [1], [2], [3] and [4]. Although, the anti-parasitic effect exerted by the T cells is largely mediated by IFN-γ, other mediators may also participate in the efficient elimination of parasites from the host [1], [2], [3] and [4]. In inbred mouse strains or humans, MHC class II-restricted CD4+ T cells recognize multiple antigens from T. cruzi [5], [6], [7], [8] and [9], whereas MHC class Ia-restricted CD8+ T cells are primarily specific for immunodominant epitopes that are expressed by surface antigens members of a large family of T.
