from Dean Baker: "It seems increasingly likely that China will begin providing vaccines to its own people, as well as those in some other countries, by December, and possibly as early as next month. The prospect of a vaccine being available that soon has to look good to people here, now that the Trump administration’s pandemic control have completely failed."
China's vaccine is based on tried-or-proven methods of using dead virus to build immunity. This may not work if the Coronavirus continues to mutate - there are currently 8 strains - but at least it should be safe and offer partial immunity, which can be updated annually in the same way.
