4 mins. He doesn't say what effec the viruses have on cancer cells. Only states that HCQ protects healthy cells. From what he said it does appear there was no HCQ present where there was lung cancer cells. It's still not clear if he was talking about sars cov2 in the case of the kidney cells. Do viruses kill cancer cells, or make them grow? Which viruses?
