Disclosed herein are recombinant adenoviruses with one or more nucleotide sequences inserted between two viral transcription units, formulations comprising the recombinant adenoviruses, and methods of treatment using the recombinant adenoviruses. In some embodiments, the one or more nucleotide sequences are inserted in an IX-E2 insertion site and/or an L5-E4 insertion site.

Provided herein are immunogenic compositions comprising a recombinant modified vaccinia virus Ankara (MVA) comprising a nucleic acid sequence encoding a flagellin, and a nucleic acid sequence encoding a heterologous disease-associated antigen, wherein the immunogenic composition induces increased T-cell and antibody mediated immune responses specific for the heterologous disease-associated antigen when administered to a subject, e.g. a human subject, and related methods and uses.

The invention relates to a live-attenuated yellow fever virus strain adapted to grow on Vero cells from a parent yellow fever virus 17D substrain that is not adapted to grow on Vero cells, wherein said live-attenuated yellow fever virus strain is less neurovirulent than said parent yellow fever virus 17D substrain.

The invention relates to a live-attenuated yellow fever virus strain adapted to grow on Vero cells from a parent yellow fever virus 17D substrain that is not adapted to grow on Vero cells, wherein said live-attenuated yellow fever virus strain is less neurovirulent than said parent yellow fever virus 17D substrain.

The present invention relates to a beta-herpesvirus, preferably a recombinant beta-herpesvirus, wherein the beta-herpesvirus comprises at least one heterologous nucleic acid, wherein the at least one heterologous nucleic acid comprises a gene encoding a cellular ligand.

A system for the rapid development of vaccines or anti-bacterial drugs is required when working with pandemics. The easiest way to formulate these new vaccines is through computational reduction of existing organisms via statistical models. Once vaccine candidates are arrived at through this method, “Super Organisms” containing all of the computationally reducible fragments can then be taken through a Crispr reduction process wherein those computationally reducible fragments are removed. The result is a vaccine candidate which has possible problematic function partially or fully removed. The “neutered” version of the virus can be tested in a lab and in clinical trials for efficacy. This patent covers a vaccine candidate utilizing computationally reducible fragments 75 to 99 base pairs in length; those fragments removed from future Covid-19 Super Organisms either collectively (as in this patent) or individually; as well as the RNA transcripts of those fragments.

The invention involves a method for modulating leukocyte activity, comprising delivering to a leukocyte a vector containing nucleic acid molecule(s), whereby the leukocyte contains Cas9 and the vector expresses one or more RNAs to guide the Cas9 to introduce mutations in one or more target genetic loci in the leukocyte, thereby modulating expression of one or more genes expressed in the leukocyte. The invention also involves identifying genes associated with leukocyte responses and experimental modeling of aberrant leukocyte activation and diseases associated with leukocytes by introducing mutations into leukocytes. The invention comprehends testing putative treatments with such models, e.g., testing putative chemical compounds that may be pharmaceutically relevant for treatment or gene therapy that may be relevant for treatment, or combinations thereof. The invention allows for the study of genetic diseases and putative treatments to better understand and alleviate leukocyte associated diseases.
