First, a Vaccine Approval. The “Chaos and Confusion.”

New York Times (tiered subscription)  –

The United States may be within months of a profound turning point in the country’s fight against the coronavirus: the first working vaccine. The first vaccines may provide only moderate protection, low enough to make it prudent to keep wearing a mask. By next spring or summer, there may be several of these so-so vaccines, without a clear sense of how to choose from among them.  Because of this array of options, makers of a superior vaccine in early stages of development may struggle to finish clinical testing. And some vaccines may be abruptly withdrawn from the market because they turn out not to be safe.
