You're looking for a light switch, two values. But, it's not that.
It's this.
And they do reduce, significantly. But, we're back at that a vaccine works best when it has very little work to do. It's not the light switch, not the forcefield, it's a reduction. Create a large enough number of events, and even a reduction is going to have a large absolute number slip through. Have 10 exposures of enough virus to infect you and 0.2 slip through, well below 1, you're fine. Have 100 exposures of enough virus to infect you and 2 slip through, maybe you're fine maybe you have a mild case. Have 10,000 exposures of enough virus to infect you and 200 slip through, your odds are way down now. Even if we then say that retransmission is super low (which clearly it is), lets say 1% for easy math. Then 1% of 0.2 is .002, of 2 is .02, of 200 is 2. So, if we let the pool of exposures get large enough, the absolute number of passing it on that happens will have a larger effect.
That they want to reduce the number of exposures now while it's a relatively low number instead of wait until it's out of control and try to clean up after the fact when it's much harder? Glad you finally agree.
It's way harder to clean up the mess than to prevent it in the first place. That should be amazingly obvious after the last 2 years.
Don’t go overboard on the second instruction obviously!
