A great interactive article in the New York Times about many of the vaccines in development around the world against the agent of Covid 19 - a long article with lots of information about the various studies from all around the world. It even covers the Russian and Chinese vaccine programs.
My latest update from Medscape lists 55 agents in human trials, and at least 87 pre clinical vaccines in animal studies at this time. The Medscape article lists at least 5 potential inhalational vaccines in studies.
Help is definitely on the way.
