Both adjuvants induced similar antibody titers using a sub-microgram dose of rH5, and both conferred complete protection against a highly pathogenic H5N1 challenge. The recent outbreak of H7N9 in early infected people within 2 months, 36 of whom died, and evidence indicated that this virus could be transmitted between ferrets and possibly humans [2] — [5].

GLA-AF stimulated a broader antibody response than SE after both the prime and boost immunization with rH5, and ferrets were better protected against homologous and heterologous strains of H5N1 virus. Another type of adjuvant targets Toll-like receptors TLRs on antigen presenting cells and the induction of Th1-mediated immune responses It was determined that a single submicrogram dose of adjuvanted vaccine protected mice and ferrets against a high titer challenge with a H5N1 virus, and that GLA-SE, relative to emulsion alone, broadened protective immunity against heterosubtypic viruses [16].

Notwithstanding these results, we have continued to test simpler GLA adjuvant formulations that lack animal products and are easier to produce. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.

Experiments using the highly pathogenic H5N1 influenza virus were performed under the guidance of the U. GLAAD is a non-profit LGBTQ advocacy organization focused on cultural change to ensure fair, accurate, and inclusive representation to advance LGBTQ acceptance.

These adjuvants contain shark-derived squalene that is microfluidized in buffer and surfactants to generate oil particles, averaging — nm in diameter, suspended in water [6] — [8]. While disease symptoms can often be mild, infection by H5N1 and H7N9 can be life-threatening.

Collectively, these emulsions induce seroprotective antibody responses to inactivated H5N1 vaccines that exceed approvable endpoint criteria in humans and provide a significant dose sparing effect [6] — [11]. Animal welfare and health was monitored daily and in instances where medical intervention was not effective, animals were humanely euthanized and every effort glaaf made to minimize suffering.

Virus stocks were prepared by inoculation of day old embryonated chicken eggs Sunrise Farms, Catskill, NY and titrated by plaque assay on MDCK cells using standard methods. These adjuvants enhance seroprotective antibody titers to homologous and heterologous strains of virus, and augment a significant dose sparing activity that could improve vaccine manufacturing capacity.

As an alternative to an emulsion, we tested a simple lipid-based aqueous formulation containing a synthetic TLR4 ligand GLA-AF for its ability to enhance protection against H5N1 infection. The ongoing threat from Influenza necessitates the development of new vaccine and adjuvant technologies that can maximize vaccine immunogenicity, shorten production cycles, and increase global vaccine supply.

Here we show that an aqueous GLA formulation GLA-AF containing nM particles and the synthetic surfactant DPPC dipalmitoylphosphatidylcholine [17]is a very potent adjuvant for rH5 vaccines in mice and ferrets and represents an important alternative to oil-in-water emulsions for pandemic Influenza vaccines.

Thus, GLA-AF is a potent emulsion-free adjuvant that warrants consideration for pandemic influenza vaccine development. Hormis l’assemblée générale de notre association, le 8 juillet à Mirecourt, le Glaaf, tout comme l’Aladfi, ainsi que toutes celles et ceux, archetiers, luthiers, musiciens [ ].

To achieve these goals, new recombinant technologies and adjuvants are needed that will shorten production cycles, maximize vaccine immunogenicity, and increase global vaccine supply. Glaaf meet this threat, pandemic preparedness goals in the US include improving manufacturing capability to supply the necessary quantities of vaccine within six months of the declaration of a pandemic, and stockpiling pre-pandemic vaccines that might provide complete or partial coverage against a new virus.

Effective adjuvants can augment protective immune responses using minimal antigen, thus providing a dose-sparing benefit that increases vaccine coverage. In addition, they mediate the priming and production of cross-reactive H5N1 antibody responses that recognize drifted strains of virus.

The discovery that the H7N7 subtype virus can also infect mammals reinforces the belief that pandemic threats extend beyond H5N1 and H7N9 subtypes [2]. Originally founded as a protest against defamatory coverage of gay and lesbian demographics and their portrayals in the media and entertainment industries, it has since expanded to queer, bisexual, and transgender people.

Currently, the most successful adjuvants for Influenza vaccines are squalene-based oil-in-water emulsions. Despite the fact these emulsions are approved for human use in the European Union, there has not been a product registration that includes emulsion-based adjuvants in the US [12][13].
