Comparing the COVID deaths with a high of up to estimated 50,000 flu deaths one year the flu vaccine wasn't effective ....
COVID deaths in the UK were with lockdown
To get some idea of the difference with / without lockdown,
compare Sweden with its neighbours, culturally similar and also with v low population density
Covid deaths / million population:
Sweden 550
Germany 109
Denmark 105
Norway 47
lockdown works:
. Sweden has 5 x deaths / million of its neighbour Denmark, culturally similar
. Sweden has nearly 12 x deaths / million of its neighbour Norway, culturally similar
. Sweden even has 5 x deaths / million of Germany - despite Germany having 10 x their population density
. The UK without lockdown would likely have suffered many times more deaths,
especially because of vastly higher population density than the Scandinavian countries
