NCT04499534

Brief Summary

To evaluate immune function in BRCA1/2 mutation carriers without cancer, specifically to determine whether immune function in healthy individuals with germline loss of function BRCA1/2 mutations, impacts overall immune health and fitness.

Outcome Measures

Primary Outcomes (1)

  • To evaluate immune function in female BRCA1/2 mutation carriers without cancer following seasonal influenza vaccination

    Analysis of the primary objective will depend on determination of the strain-specific neutralizing antibody titer change from day 0 to the last study visit, performed as the standard assay as described by the World Health Organization (WHO).

    2 years

Secondary Outcomes (2)

  • Exploratory analysis- phenotypic evaluation of B cell

    2 years

  • Exploratory analysis - transcriptional evaluation

    2 years

Interventions

To evaluate immune function in BRCA1/2 mutation carriers without cancer following seasonal influenza vaccination
