Pan-coronavirus recombinant vaccine compositions featuring whole proteins or sequences of proteins encompassing all mutations in variants of human and animal Coronaviruses (e.g., 36 mutations in spike protein) or a combination of mutated B cell epitopes, mutated combination of B cell epitopes, mutated CD4+ T cell epitopes, and mutated CD8+ T cell epitopes, at least one of which is derived from a non-spike protein. The mutated epitopes may comprise one or more mutations. The present invention also describes using several immuno-informatics and sequence alignment approaches to identify several human B cell, CD4+ and CD8+ T cell epitopes that are highly mutated. The vaccine compositions herein have the potential to provide long-lasting B and T cell immunity regardless of human and animal Coronaviruses mutations.

A vaccine for preventing CoV infection includes at least one DNA, RNA or protein sequence for S protein with at least one modification which is a full deletion or partial deletion of the SI region or a partial or full replacement of the SI region. A method of vaccinating a mammal subject against infection from at least one group of CoV includes separating a broad group of CoV into homology groups, creating a modified S protein containing at least one modification at its S1 region, and identifying at least one consensus sequence for each homology group which has a sequence identity of greater than 60% to all other members of the homology group. The consensus sequence is a protein sequence for the modified S protein, a DNA sequence encoding the modified S protein, and an RNA sequence encoding the modified S protein.

An active or inactivated recombinant vaccine against COVID-19 is described that comprises a Newcastle disease viral vector and a pharmaceutically acceptable carrier, adjuvant and/or excipient, characterized in that the viral vector is a virus capable of generating a cellular immune response that has a SARS-CoV-2 exogenous nucleotide sequence inserted,

Vaccine based on ethanol inactivated pathogens, or part thereof, are described herein. Also disclosed are certain vaccines for treating COVID-19 or other coronavirus related diseases is created by deactivating the genome, genetic material or RNA encapsulated within the shell of virus without eliminating the spikes or spike protein, which both attaches the virus to a host cell and is detected by the body to produce antibodies. Treatment of an active coronavirus with a material such as an effective amount of ethanol will both penetrate the shell and deactivate the genetic material which causes the disease, for preparation of a vaccine.

Provided are a cell-mediated SARS-COV-2 vaccine and a preparation method therefor, the steps therefor including: the construction of a SARS-COV-2 specific antigen vector presented by stem cells, and the modification and assembly with the stem cells. Two weeks after mouse immunization, approximately 50% of the mice have in vivo antibodies that show a strong positive expression, and the most significant of which being an N-gene modified stem cell vaccine.

The disclosure provides native outer membrane vesicle (NOMV) vaccines containing a coronavirus receptor binding domain (RBD) modified to be a lipoprotein. Also provided are compositions comprising a meningococcal strain having a plasmid-borne gene encoding the SARS-CoV-2 RBD modified to be a lipoprotein. Also provided are a meningococcal strain and a NOMV vaccine containing a plasmid coding for the SARS-CoV-2 RBD with a promoter/enhancer and polyA sequence that provide for expression of the RBD in mammalian cells.
