I don't believe there is a scientific consensus. But here's the deal. Even if HCQ cuts fatality by 50%, and if we assume that we can achieve herd Immunity, and if we assume that only 1 in 4 cases have been diagnosed, my math shows 2.34 million people remain left to die. If HCQ cuts that to 1.17, there is still a massive need to find something better. Those are all huge ifs.
