Symptoms of flu and COVID-19 are kinda similar specially if the COVID-19 is a mild event so sometimes difficult to differentiate. Some NYC hospital is experimentally using plasma from a recovered patients to treat infected ones. I think I heard they will give that to healthy subjects to see if they build antibodies too - a kind of crude vaccine. My concern is that in flattening the curve we may get another burst next winter though by then we may have a better handle how to handle and treat the sick. I don't think commercial scale manufactured vaccine/s for general population would be available by then. Whatever vaccine that may have been developed will likely to given to front line healthcare folks and first responders - and correctly so. It be available to the rich and well connected of course. I was at three different stores today, the fresh food items are nearly fully stocked back-up. Some frozen veggies are still not there, and the canned soups aisle is still mostly empty. Forgot to check the TP aisle! Speaking of TP I have concluded the hoarders have their noses in their butt why would someone need TP for a cold/flu like respiratory disease?
