Two studies present biological evidence that measles infections in unvaccinated children wipe out immune memories of other pathogens, putting the kids at risk of other deadly diseases.

Children were 38 percent less likely to show signs of Zika infection if they had previously had dengue.

Two types of memory T cells can preserve immunological memories for more than a decade, a study shows. 

A newly discovered protein promotes immunity to viruses and cancer by triggering the production of cytotoxic T cells.

B and T cells may be the memory masters of the immune system, but research reveals that other cells can be primed by pathogens, too.

Immune cells in skin provide powerful protection against infection, suggesting new routes for vaccination.
