The present study demonstrated how ultra weak lightcause changes in porcine epidemic diarrhea virus (PEDV) and Vero cells. Ultra weak lightactivates Vero cells by lowering pH of maintain media, but have proven no effect of killing the virus. Keywords: Coronavirus; Vero cells; alphacoronavirus; ultra weak light
