Abstract |
Pathogen reduction technologies (PRT) have been recommended by many regulatory authorities to minimize the residual risk of transfusion-transmitted infections associated with COVID19 convalescent plasma. While its impact on safety and its cost-effectiveness are nowadays well proven, there is theoretical concern that PRT could impact efficacy of convalescent plasma by altering concentration and/or function of the neutralizing antibodies (nAb). We review here the evidence supporting a lack of significant detrimental effect from PRTs on nAbs.
