Well, we can offer any and all forms of reasoning concerning Covid - for the most part, the experts all agree, we do not have enough information to make any reasonable projection of how to address this problem.
Saw an interview with Bill Gates concerning The Gates Foundation - now, on the basis of his foundation he is probably the best informed person concerning what is going on concerning remediation of the Pandemic. Dozens of top notch medical and chemical professionals are working on the vaccine and fast track testing is occurring.
Similar concerning Test Kits.
The biggest problem is we (humankind) do not have a method of treating the disease, we are treating the symptoms. We do not have a "curative" method that works. Again top notch professionals are trying dozens, if not hundreds, or regimes trying to find a curative drug. Keying on producing antibodies or a catalyst for the production of antibodies.
The Gates Foundation is working on vaccine "production facilities". That is primarily where their money is going (I believe I heard a figure of USD $125M/month) I could be wrong on the figure.
Bill Gates statements concerning this is once a working vaccine is available - it needs to be mass-produced and the worlds population needs to be inoculated - so, mass-production of the vaccine is the biggest hurdle. How long will it take to inoculate the worlds population? Well, that all depends upon how long it will take to produce enough vaccine doses to inoculate the worlds population - distribution isn't a problem, support personnel isn't a problem - production is the problem - and the Gates Foundation is concentrating its efforts on constructing vaccine production facilities and retrofitting existing factories.
The interview was quite informative and covered much ground and area.
On side layers of the onion. It is an old age disease, yes, many young folk contact it but for the most part they recover, and quickly. Of course, those with compromised immune systems have problems. And Gates emphasized that vaccines as a whole, tend not to help the elderly. Also touched on the Corona Virus what we know now is long term/life long immunity is a long shot. More than likely the vaccine will require boosters - possibly annual, like the flu shots.
