About

The purpose of this trial is to obtain serum for proficiency testing to confirm assay validity is maintained following the dosing of adults with a pediatric dose of HIL-214.

Full description

This single-arm trial serves to obtain serum for proficiency testing to confirm assay validity is maintained. Exploratory aspects of this trial include evaluating additional assays used for the assessment of immune responses to HIL-214 in peripheral-blood samples. Given the large volume of blood required, the pediatric dose will be tested in healthy adults. The main scientific rationale for the trial is to identify immune assays that can assess the generation of serum antibodies or cell-mediated immunity (CMI) specific to norovirus strains not represented in the HIL-214 vaccine (i.e. cross-reactivity).
