The present disclosure is directed to antibodies binding to and neutralizing Venezuelan Equine Encephalitis Vims (VEEV) and methods for use thereof.

The present disclosure relates to methods for transiently activating temperature-sensitive agents in one or more cells, for example by contacting one or more cells with a temperature-sensitive agent and transiently incubating the cells at a permissive temperature for inducing an activity of the temperature-sensitive agent in the cells. Additionally, the present disclosure relates to methods of contacting one or more cells in a subject with a temperature-sensitive agent and then lowering the subject's core body temperature to a permissive temperature for inducing an activity of the temperature-sensitive agent in the cells. The disclosure also relates to methods of contacting one or more cells in a subject with a temperature-sensitive agent, maintaining the subject's surface body temperature at a permissive temperature for inducing an activity of the temperature-sensitive agent in the cells. Further disclosed are methods of treating a subject with a temperature-sensitive therapeutic agent.

The disclosure relates to tropical diseases such as viral mosquito borne illnesses and the treatment thereof. The invention includes ribonucleic acid vaccines and combination vaccines, as well as methods of using the vaccines and compositions comprising the vaccines for treating and preventing tropical disease.

Method for producing a defective interfering viral genome (DVG), defective interfering particles comprising the DVG, and methods and uses thereof.

Provided are vaccines for eliciting an immune response. The vaccines for eliciting an immune response comprise RNA encoding an immunogen, which 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.

The present invention relates to a process for producing an immunogenic live attenuated Chikungunya virus, as well as pharmaceutical compositions comprising the same.

The present invention includes composition and methods for making multivalent vaccines for immunization against Flavivirus and/or arboviruses including a multivalent Virus Like Particles (VLP) and mixtures thereof, the method comprising: method of making a Flavivirus and/or arboviruses Virus Like Particles (VLP) comprising: inserting two or more nucleic acids that encode at least one Flavivirus protein into a lentiviral backbone vector; generating a lentivirus by transfecting a first cell line with the lentiviral backbone vector and isolating the lentivirus therefrom; transducing a second cell line with the lentivirus; culturing the transduced cell line under conditions in which the multivalent Flavivirus Virus Like Particles (VLP) are released from the cell line; and isolating the Flavivirus Virus Like Particles (VLP) from a culture supernatant, wherein a cell line makes a virus-specific VLP, and the VLPs are purified and then mixed in different combinations to make the multivalent vaccine.

Disclosed herein is a method for producing human antibodies against a pathogen comprising injecting a non-human animal with a pathogen-derived DNA vaccine in at least two locations of the animal; injecting the animal with an adjuvant in a location of the animal different from the location of the DNA vaccine location; collecting plasma from the animal after the injections; and purifying polyclonal antibody from the plasma.

The present disclosure provides compositions and methods for the treatment of cancer. More specifically, the present disclosure provides compositions and methods utilizing a combination of an oncolytic viruses, such as Sindbis virus, and antibodies directed against a co-stimulatory molecule or to an immune system agonist molecule, such as anti-OX40 antibodies and anti-4-1BB antibodies.
