at this stage, because the virus is already seeded, a lockdown is not going to do anything at all.
again: this is not a second wave. this is the conclusion of the first wave, the part of it that got into the general population.
as an effective vaccine is likely fleeting - we've been lucky so far, but this thing will mutate faster than we can fight it - if we don't allow the virus to spread in young people, we'll be in and out of lockdown forever.
when will we wake up and realize how stupid we're being?
