They don't care, Matthew. There can't be a cure; otherwise the lockdown/crisis are over, and there's a reason they want it to continue.
Even the big pharma (Gilead et al.) announced various other cures, but there has been total silence out there about those also.
If there's a cure, there's no need for a vaccine, no need for lockdowns and masks and control, no reason to steal trillions from the economy and deliver it to the bankers.
