There are several registries out there, with masses of research being reported. The papers aren't reporting it yet because a) it's not sexy (yet) and b) it's going to take time. There may be a vaccine. Nobody knows for sure yet although several are at the test phase, and many brave people have volunteered. In the meantime, other interventions may help - masks, existing drugs, social distancing, better hygiene. The jury's still out on some of them.
Most of the big STEM publishers are making research articles and other information available free of charge as well. In over 20 years of being a librarian (mainly health and science related, with a dash of education and business and a couple of other subjects) I've never seen anything quite like this sudden explosion of knowledge. Historically, it's a very, very sad fact that medical and scientific knowledge has often increased dramatically in times of conflict.
And that's just the clinical and science side of things, let alone the environmental factors. So in that respect, yes, the amount of knowledge is increasing at an unprecedented rate, with even those who've never picked up a science book since school taking an interest.
When I looked yesterday there were close to 1,000 clinical trials taking place, or about to take place, that mentioned COVID-19 explicitly. Today there are over 1,000. You can search at clinicaltrials.gov/ct2/home - it's not a secret. There are other sites out there with no particular axe to grind beyond making information available, in a free and neutral way.
The brightest scientific minds on the planet are working on this. It's not their fault if some governments won't listen, but it's one of the reasons I'm so very cynical about what's coming out of the mouths of politicians and journalists in 3 countries in particular, maybe 4, of which the UK is one.
That's when I'm not listening to the Barney Rubble show in sheer horror and hysteria with a big bucket of popcorn in the early hours!! Our politicians may have handled some aspects of this crisis in a questionable manner, but they're not unhinged in that way.
