It's a fantasy that he is announcing it like it is some new idea - that he'll create a task force, and they will just invent new treatments to order, by the autumn, in pill form if you please , just because he's asked for it.
Of course people have thought of the ideas before, of course they'll be working on this continually for the past year, of course they'll be trying to do it as soon as possible and in the most effective/convenient way. They didn't need Boris' permission or ideas. Money, now yes, that might be helpful, the more money and resources that can be invested in treatments, great, things might get done faster, as with the vaccines.
But it's the way it was all announced as if it was a definite plan for the autumn that was some new idea of his that is the fantasy. They'll get invented as soon as possible, they'll get them trialled and distributed as soon as possible, because that's what scientists do, not because Boris has ordered them.
Great to have new treatments that can be used at home, nobody is arguing that! And chances are there will be some, too. But not specifically because he's decided that there should be.
