One major advantage Avacta have, is that if there is a variant that escapes an 'N' test, then the developer will have a much longer lead time to come up with a new test / new antibody (3-6 months). Despite there being less of a possibility of a mutations in the 'N' protein, it is still a possibility, so would the govt want to commit to an 'N' sovereign test, knowing that it could be redundant for 3 to 6 months should such a mutation occur? Wouldn't they rather have a highly accurate 'S' test, which targets the parts of the 'S' protein less susceptible to mutations, knowing that Avacta can knock up another affimer in about one month, in a worse case scenario. Common sense dictates the Avacta route.
Of course, there is also an argument to be made for two sovereign tests...best 'S' test and best 'N' test, to cover all bases, until such time as Avacta/Mologic come up with the silver bullet S/N test.
