Countermeasure gaps

A stage is not a measure of effectiveness, and a blank is not a zero. This table says what stage the furthest-advanced countermeasure has reached, for the sources this project has actually searched. A hatched cell means nobody has looked yet. A cell reading “none found” means the sources searched contained nothing — which is weaker than saying nothing exists, because the sources are not complete registers.

Vaccines come from the site's vaccine pipeline dataset. Antivirals and antibodies come from current US drug labels, so a drug approved only outside the US will not appear. Read this as a map of what this project has established, not as a map of the world.
