TWiV reviews the six known coronaviruses that infect pigs and what can be learned about human infections, and how the giant Mimivirus DNA genome is organized into a nucleocapsid.
TWiV reviews evidence that COVID-19 mRNA vaccination of both uninfected and previously infected persons elicits cross-variant neutralizing antibodies, and directed evolution of a bacterial protein to form a virus-like capsid that specifically packages its encoding mRNA.
Brianne returns to the TWiV Gang to discuss the distribution of proteins on the influenza viral genome, and the evolution of myxoma virus that was released in Australia to control the rabbit population.
