Note: AH has access to data, computers, and internet even more than me. I have 1 brain. They have many brains to work on models and monitor global situation
We could have A (no COVID→normalcy back)
But GOA and AH chose B for all of us 1/
Please note how close the reality is to the centre trajectory projected 8 weeks ago, when overall cases were still going down
The spread of SARS-CoV-2 is HIGHLY predictable.
(If someone tells you otherwise, that only means that it is beyond their personal analytical abilities) 2/
Others have been saying the same thing as me. Below are models by Prof. Colijn. From *May 31* (!).
GOA and AH and some advisors must have seen them (that’s their job), but they did this: 🙈🙉 lalalala!, while implying that “the pandemic is over”.
GOA and AH lifted mask mandates & allowed large gatherings. That ensured that vaccines, in-person school break & warm weather won’t have a chance to stop the spread “by accident”. And they didn’t.
Spread must go on.🎶
Since 14 months we are being forced to live with COVID.

For how many years more?
5/
A reminder:
“Living with COVID” is a decision, not a biological inevitability.
W/ elimination strategy, a region can stop community transmission in just 5-10 weeks, and get back to a relative normalcy, which is sustainable
We can’t vaccinate our way out of the pandemic.
We need both: Vaccines AND Public Health (PH) measures.
It was barely possible w/ original variant (A). W/ Delta, both PH measures and vaccines became less effective (B). But combined – they may still work.
Theoretical model:
1/
Even if vaccines are only 60% efficient against transmission & only 75% eligible people (64% total) get vaccinated, by combining PH measures & vaxx we may still be able to control the spread (C). Barely.
But…
2/
But if by allowing the reckless spread we culture a variant 2x more transmissible than Delta → our current strategy (i.e. acting only when ICUs get full) won’t work anymore.
Our tools: PH measures & vaccines will not be effective enough to quickly halt the exp. growth (D)
Alberta: Current measures made the growth rate less extreme.
B117 is doubling now every 20 days instead of every 7 days.
It's still very fast - similar to doubling time in the 2nd wave (18 days)
Current measures are insufficient to bend the curve downwards.
Ln scale graph 👇
At this rate we can expect:
3,000 daily new cases on May 12
4,000 daily new cases on May 22
2/
This wave is worse than the fall one.
2nd wave: at 1877 daily cases we had 100 ICUs
3rd wave: at 1860 daily cases we have 146 ICUs, and *we are still growing*
That's *despite* many people being already vaccinated. W/o vaccines it would be even worse.
