mVSV virus vector and virus vector vaccine, and COVID-19 vaccine based on mVSV mediation

The invention provides an mVSV virus vector, i.e., attenuated mVSV obtained after multiple modification mutations occur to an M protein amino acid site of a wild Indiana strain VSV, and an optimized heterologous antigen gene is preferentially integrated to a double cloning site area of an mVSV packaging core plasmid pmVSV-Core at the same time. The mVSV virus vector vaccine comprises a heterologous antigen gene which fuses or embeds a target virus between G and L genes of an mVSV vector envelope, wherein the antigen gene comprises an enveloped and embedded antigen gene encoding the target virus, an embedded combination antigen gene or a fused antigen gene; the mVSV virus vector is embedded or fused with a dominant antigen of spike protein S of an SARS-CoV-2 pathogen; the dominant antigen is preferably selected from a receptor binding domain of spike protein S, namely RBD; and a COVID-19 vaccine based on mVSV mediation is formed. The vaccine has good prevention or treatment effect on COVID-19 infected people.

Hepatitis b virus surface antigen as a mucosal immunostimulator and the resulting formulations

The invention relates to a mucosal surface antigen which is used to promote and increase in the immune response against co-administered antigens in the formulations out line in the invention. Said novel formulations are obtained from the dual use of the surface antigen as an immunostimulatory agent and, at the same time, as a vaccine antigen. In this way it is possible to obtain multiple formulations of the hepatitis B surface antigen and heterologous antigens, with immunogenicity levels similar to those obtained following parenteral administration and with a reduction in components that can dispense with the use of nasal adjuvants, thereby converting same antigens into elements that can promote an increase in the response to the other co-administered antigens. Said novel use of the hepatitis B virus surface antigen and the resulting antigen formulations can be used in the pharmaceutical industry as therapeutic and preventive vaccine formulations.

Methods for Isolating and Proliferating Autologous Cancer AntiGen-Specific CD8+ T Cells

Provided is a method for isolating and proliferating autologous cancer antigen-specific CD8+T cells, and more particularly, a method for selecting an epitope recognized by CD8+ T cells from autologous cancer antigens present in blood of individual cancer patients; and isolating autologous cancer antigen-specific CD8+ T cells by using a peptide of the selected epitope, and a method of massively proliferating CD8+ T cells by using the method. According to the present invention, it is possible to isolate autologous cancer antigen-specific CD8+ T cells by using the peptide of the CD8 T cell epitope of the autologous cancer antigen present in blood of individual cancer patients instead of a heterologous antigen. Therefore, by using T cells recognizing the autologous cancer antigen, it is possible to effectively select and eliminate cancer cells derived from the cancer patient's own cells. Thus, T cells can be applied to treatment and alleviation of cancer diseases without side effects.
