Unique influenza A cross-reactive memory CD8 T-cell receptor repertoire has a potential to protect against EBV seroconversion

Detection of unique, functionally influenza A/EBV crossreactive oligoclonal CD8 T-cell repertoires in rare individuals who remain EBV-seronegative into fourth decade of life suggests that T-cell crossreactivity dependent heterologous immunity may protect from EBV infection.
