A method for producing at least one microneedle containing a vaccine for transdermal delivery of the vaccine to a patient includes preparing microparticles or nanoparticles of encapsulated vaccine by preparing a solution comprising a vaccine antigen and a biocompatible polymer matrix; and spray drying the solution to form the microparticles or nanoparticles. The method includes the further steps of preparing a film composition including at least one pre-polymer solution; preparing a suspension comprising the microparticles or nanoparticles and the film composition; loading the suspension into a 3D printer; printing, via the 3D printer, at least one microneedle made from the suspension; and, converting the pre-polymer solution into a cross-linked biopolymer by exposing the at least one microneedle to UV light. Also disclosed are microneedles containing a vaccine for transdermal delivery.

The invention provides adenoviral vectors comprising transgenes encoding Lyssaviral antigens. The vectors can be used to produce vaccines for the prophylaxis, amelioration and treatment of diseases caused by Lyssaviral diseases, e.g., rabies.

The present invention relates to immunogenic compositions comprising RSV F protein, methods for preparing compositions that contain RSV F protein ecto-domain polypeptides, and to certain engineered RSV F proteins and nucleic acids that encode the engineered RSV F proteins. Compositions prepared using the methods can contain RSV F protein ecto-domain polypeptides in a predominant or single desired form and conformation. The invention also relates to methods for inducing an immune response to RSV F.

RNA encoding an immunogen is delivered to a large mammal at a dose of between 2 μg and 100 μg. Thus the invention provides a method of raising an immune response in a large mammal, comprising administering to the mammal a dose of between 2 μg and 100 μg of immunogen-encoding RNA. Similarly, RNA encoding an immunogen can be delivered to a large mammal at a dose of 3 ng/kg to 150 ng/kg. The delivered RNA can elicit an immune response in the large mammal.

The present invention provides a recombinant attenuated respiratory syncytial virus (RSV) comprising F protein of stabilized pre-fusion RSV, or comprising protein consisting of the amino acid sequence represented by SEQ ID NO: 2 or functional fragment thereof, and provides genome of the recombinant RSV and a recombinant vector comprising the genome. The recombinant attenuated RSV can be provided as a live vaccine strain which maintains infectability and has excellent safety and stability.

The disclosure relates to respiratory syncytial vims (RSV) ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

The present invention relates to aqueous compositions conferring improved stability to poxvirus during storage as well as to the use of such compositions and methods for preparing the same. The compositions comprise recombinant human serum albumin (rHSA), gelatin or arginine, or combinations thereof.

Provided is an antigen including a recombinant respiratory syncytial virus (RSV) F protein, wherein the recombinant RSV F protein includes an antigenic region flanked with an HRN region and an HRC region, and the antigenic region includes one or more antigenic sites selected from the group consisting of site Ø, site II, and site IV. The present disclosure also provides a nucleic acid molecule encoding the antigen and a vaccine composition including the antigen for eliciting an immune response against RSV.

The disclosure describes respiratory syncytial virus (RSV) ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

Disclosed herein are compositions for vaccination against respiratory syncytial virus (RSV) comprising a RSV F polypeptide stabilized in a prefusion conformation and an inulin adjuvant. Also disclosed herein are methods of vaccinating a subject against a respiratory syncytial virus (RSV) infection comprising administering to the subject an RSV F polypeptide stabilized in a prefusion conformation and an inulin adjuvant. In some embodiments, the subject is a female, and the method can reduce RSV infection in the subject and/or in the offspring of the subject. In some embodiments, the method decreases vaccine-enhanced respiratory disease (VERD) and/or eosinophilia in the subject or offspring of the subject.
