Ibyavuye mu kugerageza uwo muti ku barwayi 1.219 bashobora kuzahazwa cyane, bari bamaze iminsi banduye Covid, byerekanye ko 0.8% y’abahawe Paxlovid binjijwe ibitaro mu gihe bashyitse 7% ku bahawe uruhendo/utari wo rw’uwo muti (placebo). Bahawe uwo muti hashize iminsi itatu bagaragaje ibimenyetso bya Covid.
