Oh for sure … by “lockdown” I’m referring to the general suite of civil measures including masks etc … basically anything other than a vaccine or preventative medicine.
And of course, an additional dimension here is that influenza is no slouch of a virus … eradicating the flu would be significant for public health. So to my mind, kinda accidentally eradicating a strain of it should be a big “huh … how did we do that again?” rather than just “now we need to adjust our vaccines”.
