Viruses That Infect Humans and Themselves

Mice that have been genetically altered to have human immune systems. One contains 60 particles, all from the sars cove to homotypic because it's all the same abirusthe ar two. Then they created one from eight different coroniviruses. They did not include any receptor bind in domains, from sar's cove, from the first sars virus. So every coronovirus will get targeted enough, even ones that are novel, that are not part of mosaic eight and provide effective immunity.
