This is to argue from the point of absurdity, though. Future variants of this virus have to be contained before they cause us to get to the point of lockdown, especially a national lockdown. To do that, we need a means of containing it. That is what I am saying we need to have, a system that can identify outbreaks, contain them and give the folk developing future vaccines an idea of what the virus is developing into.
Of course that system can then be used against the next pandemic that might come along, or (heaven forbid) a hostile state who has noticed that this is actually a much safer way of weakening the West than anything involving bombs.
If we don't have that, then we can't contain it; making relevant and effective boosters is also much more difficult. It also leaves a massive gaping hole in our national defence.
Finally I'd have hoped this "well, we cope with the flu" nonsense would have been killed off by this past year, but it seems not. Flu kills more than ten thousand people a year in this country, and theres a good chance (based on other countries' performance) that at least half of them might be preventable.
I think that's adding 1+1 and getting 3.
I've said T&T will persist for years, but it won't be with the aim of preventing a lockdown; it'll be with the aim of detecting dangerous mutations for a booster shot, because the immunogenic response of a vaccine prevents serious illness and, bar a complete change in how the virus works (not the spike protein, I mean in terms of how it actually works inside the human body) and an unprecedented mutation to make it more lethal, that immune response from the vaccine will remain consistent enough to provide a baseline prevention of illness.
No, for me, the reason we actually need T&T and a focus on viral detection in the future is to stop the
next pandemic, not necessarily the next COVID strain.
Also, the last bit for me shows the weakness in your argument - we could very well prevent flu killing a few thousand people a year; but the question is whether we
want to, given the trade off in civil liberties that would involve. I'd say, clearly, no, we don't. If general hygiene measures like hand sanitisers become more commonplace, good, but we shouldn't be aiming to prevent every death from COVID/flu as the trade off is unviable - notably because by having extreme measures in place you create
more death through mental health pressures, people skipping medical appointments for other matters and so on.
People can't just exist; they need to be able to live. It's a balancing act. If 5,000 people die a preventable death in the UK per year from COVID/flu in future years, but it means people live their lives, so be it. It sounds cold to say, but that's just the reality of it.
