摘要:
The present invention relates to a novel effective dry powder vaccine formulation that increases the immune response in the host. The formulation comprises of an antigen entrapped into a polymer particle, coated with alum, finally spray dried into a dry powder. This formulation is used to elicit long lasting higher antibody titers than alum adsorbed antigen or admixture of polymer entrapped antigen and alum.

Multilayer films comprise polypeptide epitopes from RSV. The multilayer films are capable of eliciting an immune response in a host upon administration to the host. The multilayer films include at least one designed peptide that includes one or more polypeptide epitopes from RSV. Specifically, the multilayer films include two polypeptide epitopes from RSV, such as an epitope that elicits a specific T-cell response such as a cytotoxic T-cell response, and an epitope that elicits a specific antibody response.
摘要:
RNA encoding an immunogen is delivered in a liposome for the purposes of immunisation. The liposome includes lipids which have a pKa in the range of 5.0 to 7.6 and, preferably, a tertiary amine. These liposomes can have essentially neutral surface charge at physiological pH and are effective for immunisation.
摘要:
The present disclosure provides compositions and methods useful for treating influenza. As described herein, provided compositions and methods are based on the development of certain compositions that include an influenza virus hemagglutinin antigen in combination with lipid vesicles that include a non-ionic surfactant (NISVs) and/or in combination with a TLR-3 agonist adjuvant. In certain embodiments, provided compositions remain potent even when they are not stored in a standard cold-chain system (i.e., they are thermostable).
摘要:
La presente invención se relaciona con el campo de las composiciones vacunales para el tratamiento efectivo o preventivo de infecciones de transmisión vertical, particularmente la malaria y preferiblemente la humana causada por Plasmodium falciparum. El objetivo técnico que se persigue es usar los tolerógenos trasferidos tempranamente de la madre al feto/recién nacido y formularlos con potentes adyuvantes inductores de respuestas Th1 y T citotóxica para su uso en vacunas profilácticas o terápeuticas contra las infecciones de transmisión vertical y particularmente la malaria. El empleo de estas formulaciones por vía parenteral o mucosal o ambas a la vez en edades tempranas revierte la tolerancia inducida por la transferencia de tolerógenos y con ello inducir respuestas protectivas.
摘要:
The present invention relates to immunogenic compositions comprising HIV-1 antigens and uses thereof in the prevention and/or treatment of HIV-1. In particular, the invention relates to the use of HIV-1 antigens from one clade in the prevention and/or treatment of disease associated with HIV-1 infection from a heterologous HIV-1 clade.
