China's just rolled out an inhaled vaccine, and having vaccines that target the nasal passages specifically seem very promising for preventing infection. If I could, I'd get that vaccine.
It is inconceivable that the official numbers (5226 deaths) are being understated to a significant degree, because if they were, a threshold would be crossed rendering containment impossible, and 2-4 million people would then die. January and February 2020 in Wuhan looked like the apocalypse. An event 500-1000x as bad could not be hidden.
