It's so depressing that after almost 2 years of pandemic we seem to have zero decent data and zero consensus regarding the real effect and usefulness of things like masks, lockdowns, seasonality of the disease, or what is the long term plan for countries trying to achieve 100% vaccination rates. It seems like every single decision is purely political and the next decisions are just cover-ups so that previous decisions don't blow up on the people who took them. I guess zero data means zero responsibility.
