2. Death rates by age stratification. The best science I have seen showing IFR by age is this study titled Assesssing the Age Specificity of Infection Fatality Rates for COVID-19: Meta-Analysis & Public Policy Implications. Check out this chart: I wish this chart broke the age down even further, particularly in the 0-10 or 0-20 age range, where the IFR is effectively zero.
These facts are slowly making their way into the mainstream, and the paper concludes: “Age and fatality risk for COVID-19 are exponentially related. In non-technical terms, COVID-19 poses a very low risk for children and younger adults but is hazardous for middle-aged adults and extremely dangerous for elderly people.
3. Herd Immunity Threshold. Since my previous blog post, when I wrote about Herd Immunity Threshold in detail, it’s becoming even more clear that the “H.I.T.” of COVID-19 is very likely in the 10-20% range, rather than the 60-70% range that was originally thought. It would be impossible to overstate the importance of this difference, because it supports exactly WHY COVID-19 has already reached herd immunity in most of Europe, and WHY we’re almost done here in the U.S., too. Here’s one new paper, Herd immunity thresholds for SARS-CoV-2 estimated from unfolding epidemics.LOCKDOWN LUNACY 3.0—It’s over. • Children’s Health Defense
