Described herein is a method of preventing or treating a disease in a mammalian subject, comprising administering to the subject who is in need thereof an effective dosage of a pharmaceutical composition comprising a virus like particle (VLP) comprising: an alphavirus replicon comprising a recombinant polynucleotide, wherein the polynucleotide comprises a sequence encoding both subunits of a human class II major histocompatibility antigen, a retroviral gag protein, and a fusogenic envelope protein, wherein the VLP does not contain an alphavirus structural protein gene.

Described herein are single-domain antibodies that might serve as alternatives to conventional monoclonal antibodies for either the detection or treatment of Chikungunya Virus (CHIKV).

The present invention includes nucleic acids, proteins, Chikungunya virus (CHIKV) Virus Like Particles (VLP), and methods of making a Chikungunya virus (CHIKV) Virus Like Particles (VLP) comprising: inserting one or more nucleic acids into a lentiviral backbone, wherein the nucleic acid encodes one or more Chikungunya virus (CHIKV) proteins; transfecting the one or more nucleic acids into the lentiviral backbone into a cell line; culturing the transfected cell line under conditions in which the Chikungunya virus (CHIKV) Virus Like Particles (VLP) are released from the cell line; and isolating the Chikungunya virus (CHIKV) Virus Like Particles (VLP) from a culture supernatant.

Aspects of the disclosure relate to nucleic acid vaccines. The vaccines include one or more RNA polynucleotides having an open reading frame encoding one or more Chikungunya antigen(s), one or more Zika virus antigens, and one or more Dengue antigens. Methods for preparing and using such vaccines are also described.

The invention provides adenoviral vectors comprising transgenes encoding Chikungunya virus antigens. The vectors can be used to produce vaccines for the prophylaxis, amelioration and treatment of diseases caused by Chikungunya virus infections.

This invention relates to chimeric coronavirus S proteins and methods of their use, for example, to treat and/or prevent diseases or disorders caused by infection by a coronavirus.

A method of vaccinating a subject is provided, where a cancer protective response is produced. A first vaccine comprises an adenovirus vector comprising at least one nucleic acid molecule that produces a cancer protective response is administered, followed by one or more second vaccines comprising an alphavirus replicon particle comprising RNA comprising or produced from the nucleic acid molecule. In an embodiment the cancer is prostate cancer.
