I'll take my chances that it does fight all viruses...and even hospitals and clinics are using higher doses of Vit C during this crisis and in general. My grandgirl works in a clinic that dispenses the Vit C.

And more so, Grape Seed Extract is 50 x's more powerful than C so taking Grape Seed for 25 yrs has kept me cold and flu FREE for all these years.....

I believe it does WORK and works very well.
