That will give you a pretty good idea as to what the level of immune evasion is. That process will take likely two weeks or more, perhaps even sooner, depending upon how well the virus grows in the isolates that we get, and in those countries in which there are a lot of cases like South Africa, the computational biologists and the evolutionary biologists are going to be getting a good feel as to what the competition of this virus would be with Delta. Those are just a few of the things that will take a couple of weeks to a few weeks to learn.
