Election day is 85 days away. There is no way it will be done by then and there never was any chance there would be. Late this year or early next year would be record time so shoot for that.
The common cold is a corona virus. No successful vaccines created after decades of trying. Any successful corona virus vaccine would be a first of it's kind. IMHO, it ain't gonna happen; not this year, not next year, not in my lifetime.
