The present disclosure provides a method for the treatment or prophylaxis of coronavirus infection, comprising administering a therapeutically effective amount of an immunomodulator to a subject in need thereof or at risk of coronavirus infection. A vaccine composition comprising a pharmaceutically effective amount of an immunomodulator is also provided.

The present invention provides an anticancer agent containing the following (1) and (2): (1) HVJ-E (hemagglutinating virus of Japan envelope), (2) an inhibitor of an immune checkpoint protein.

The present invention provides antibodies that bind to the cat allergen, Fel d1, compositions comprising the antibodies, nucleic acids encoding the antibodies and methods of use of the antibodies. According to certain embodiments of the invention, the antibodies are fully human antibodies that bind to Fel d1. The antibodies of the invention are useful for binding to the Fel d1 allergen in vivo, thus preventing binding of the Fel d1 allergen to pre-formed IgE on the surface of mast cells or basophils. In doing so, the antibodies act to prevent the release of histamine and other inflammatory mediators from mast cells and/or basophils, thus ameliorating the untoward response to the cat allergen in sensitized individuals. The antibodies of the invention may also be useful for diagnostic purposes to determine if a patient is allergic to the Fel d1 cat allergen.

This invention relates to adjuvant formulations comprising various combinations of triterpenoids, sterols, immunomodulators, polymers, and Th2 stimulators; methods for making the adjuvant compositions; and the use of the adjuvant formulations in immunogenic and vaccine compositions with different antigens. This invention further relates to the use of the formulations in the treatment of animals.

Field of application: the invention relates to veterinary medicine and, in particular, to vaccinology and pharmacy, and is intended for the prevention and treatment of infectious and other diseases of humans and animals, where low allergenic low reactogenic vaccination is used. The essence of the invention: developed vaccines with increased immunogenicity, low allergenicity and reactogenicity, containing antigen/toxin and adjuvant, wherein that they contain vaccine antigen/toxin inactivated by electromagnetic radiation in the ultraviolet and visible regions of the spectrum in the presence of a solution of photosensitizer and salts of divalent metals, and then covalently modified according to the residues of amino groups and hydroxyls groups of antigen/toxin available for modification, at least two modifying agents at the same time in terms of 0.01-10.0% of the mass concentration of the antigen/toxin protein, and as an adjuvant it contains hydrosol hydroxide ferric chloride.

A vaccine composition and method of vaccination are provided useful for immunizing a subject against a rotavirus. The vaccines include rotavirus strains CDC-9 and CDC-66, fragments thereof, homologues thereof, or combinations thereof. Inventive vaccines may include a fragment of CDC-9, CDC-66, homologues thereof, or combinations thereof. Methods of inducing an immunological response are provided by administering an inventive vaccine.

An attenuated vaccinia virus GAB-1 and its use in a vaccine for treatment of papillomavirus lesions is described. In preferred embodiments, the Lederle-Chorioallantoic strain of vaccinia virus is serially passaged in chicken embryo-fibroblast (CEF) cells by at least 100 passages. GAB-1 has reduced virulence and is safe to use without side effects after attenuation by serial passaging, but remains highly immunogenic. Experimentation has found that GAB-1 is much more immunogenic than other strains of vaccinia virus, including Western Reserve (WR) and modified Vaccinia Ankara (MVA). GAB-1 can be used safely in humans for treating tumorous lesions caused by human papillomavirus (HPV).

The subject invention pertains to isolated influenza virus that is capable of infecting canids and causing respiratory disease in the canid. The subject invention also pertains to compositions and methods for inducing an immune response against an influenza virus of the present invention. The subject invention also pertains to compositions and methods for identifying a virus of the invention and diagnosing infection of an animal with a virus of the invention.

This disclosure relates to multivalent enterovirus vaccine compositions and uses related thereto. In certain embodiments, the disclosure relates to vaccine compositions comprising multivalent, mixtures of enterovirus (for example HRV) serotypes or recombinantly produced variants or recombinantly produced viral capsid proteins. In certain embodiments, the disclosure relates to methods of immunization comprising administering an effective amount of compositions disclosed herein to a subject diagnosed with, exhibiting symptoms of, or at risk of an enterovirus infection.

Herein is described oncolytic viruses for use as immunologic adjuvants. There is provided a method of adjuvanting an immune response to an antigenic protein in a mammalian subject by administering the oncolytic virus and at least one antigenic peptide, with the latter not encoded by the former. Without the requirement for the virus to encode the antigenic protein, therapies may be readily personalized or formulated. The virus may be attenuated or inactivated. Prime:boost therapies for tumours are also provided, in which the prime comprises at least one antigenic protein, the boost comprises a virus and at least one antigenic protein, the at least one antigenic protein of the prime and the at least one antigenic protein of the boost are based on the same at least one tumour associated antigen, and the at least one antigenic protein of the boost is not encoded by the virus of the boost.
