Provided herein are methods and compositions for stabilization of active agents. The active agents are distributed, mixed or embedded in a silk fibroin matrix, thereby retaining the bioactivity of the active agents upon storage and/or transportation. In some embodiments, the storage-stable vaccine-silk compositions are also provided herein.

A recombinant measles viral vector comprising a nucleic acid sequence encoding a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) spike glycoprotein is provided. Polypeptides comprising the SARS-CoV-2 spike glycoprotein also are provided, as well as related nucleic acids, vectors, and compositions. The polypeptides, nucleic acids, vectors, and compositions can be used in methods of preventing, inhibiting, reducing, eliminating, protecting, or delaying the onset of an infection or an infectious clinical condition caused by coronavirus and methods for inducing an immune response against a coronavirus.

This document relates to methods and materials for making and using viruses (e.g., measles viruses or adenoviruses) having a reduced susceptibility to antibody neutralization (e.g., antibody neutralization by serum from measles virus vaccines). For example, recombinant morbilliviruses (e.g., recombinant measles viruses) having a modified H gene and a modified F gene, as well as methods of using a recombinant virus are provided.

The invention relates a recombinant measles virus plasmid capable of expressing a human telomerase reverse transcriptase (hTERT) protein fused at N-terminus with a protein enhancing addressing of the hTERT protein to proteasome. The invention further relates to a vaccine comprising said plasmid or particles rescued therefrom, and uses thereof, especially in preventing or treating a tumor in a patient.
