America has already begun Human Trials for the Coronavirus Vaccine
Both the cases in China and the cases on the cruise ship that was isolated until their patients could recover (designated 'other') have both had more time than any other territories, to wait out the incubation cycle of the disease that requires atleast 21 days under strict observation to pass through ones system, before they can finally be cleared, which is what has happened in both China and on the cruise ship.
Only 2.4% of those infected are under the age of 18 and this disease's mortality rate is somewhere in the neighborhood of 3.4% (but that mortality rate increases to about 7% if you have a weak respiratory system or if you have diabetes or cancer). So I don't think it's the next #SpanishFlu of 1918, like the media is doing a good job of scaring everyone into thinking. There's definitely some hope at the end of the tunnel and most of the people who'll survive this #pandemic will do so without ever having needed a vaccine (so when they FINALLY create one, don't rush for the shot, the way other dumb asses scrambled for toilet paper). Other countries don't have a worse off medical system than China, but what China has that is the envy of America and other nations is population control over their masses, and that is why they were able to use the kind of austere methods that would never be possible in western countries.
