Abstract
The increasing frequency of pathogenic coronaviruses in the human population has raised public health concerns about possible future pandemics. It is critical to understand whether immune responses to the current circulating coronaviruses provide protection against related viruses or those that may emerge in the future. In this issue of the JCI, Dangi, Palacio, and co-authors detail the extent of coronavirus cross-protection following both vaccination and natural infection and ultimately used murine models to highlight the mechanism behind this heterotypic immunity. This study provides insight into the possibility of a pan-coronavirus vaccine that could protect humans against future coronavirus outbreaks.
