Excerpts from a recent social media post: It is important to understand the difference between Case Fatality Rate (CFR) and Infection Fatality Rate (IFR). IFR is the figure we need to focus on. A comprehensive Stanford University study showed that, across 51 locations, the median COVID-19 IFR was 0.2%. This shows very clearly that the…

We look at more worst-case scenarios in New Zealand for the current Delta outbreak. Increased vaccination levels has not appeared to produce a significant drop in daily cases numbers. However very few hospitalisations are fully-vaccinated. Over 75% of New Zealand’s population (over 12) has received a second dose of vaccine and is or will be…

We use Norway data to estimate a worst-case scenario for Norway and New Zealand. We anticipate we could have 500,000 cases over a one-year period and 2100 deaths. Even using Norway’s actual case data provides a scary scenario for New Zealand. New modelling prepared for the Government by Professor Shaun Hendy suggests that New Zealand…
