They did. Australia publishes data on this and the effect is profound. Australia has had about 400 flu cases in 2021, compared to a 5-year average of about 50000. None of those cases in 2021 have been hospitalised or led to death, when in the average year there’d be about 150. 2020 also yielded a similarly precipitous drop in cases.
