“Herd immunity” is really only achieved when
greater than 70 or even 90%, at a minimum, of the general population has been exposed to the virus or vaccine. This also assumes that once having been exposed you are forever immune to catching it again (but we won’t bother considering that just now).
Sweden has 10 million people. If we allow 80% (a more reasonable estimate) as needed to achieve herd immunity, then 8 million of them must be exposed. Doing this the natural method, with disease, not vaccine, then herd immunity comes at the expense of roughly 200,000 deaths in Sweden. (2.5% fatality rate x 8 million). Never you mind the 300K to 500K with lasting damage to their lungs, kidneys, brains and hearts.
Now, assuming immunity lasts more than 1 year, Sweden is
mostly safe.
Or.....
You mandate masks and social distancing, you shut down unnecessary businesses (and/or mandate stingent limited traffic and cleaning procedures) and get through till spring of 2021 with <5% infected (=500,000 cases with 12,500 deaths and 18 to 32K long term issues). Then vaccinate 95% of the population and live well and safely.
200,000 deaths
vs 12,500
plus ~400K damaged
vs 25K damaged
Thats almost 180,000 lives saved and 350,000 people without long term organ issues, and all the costs that has yet to entail.
Also, business is NOT going to sing merrily along with death sweeping through the population at the natural disease’s pace. No. It will not. So stop deluding yourself that it will child.
If you’re curious as to USA numbers, that’s easy. Just multiply everything I said above by 33.
a.k.a. - 6,600,000 deaths and 13,200,000 injured the natural method.
vs. 412,500 dead and 825,000 injured by taking precautions till mandatory (>95%) vaccinations.
PS...
My estimates for the natural method are likely too low, since I’m assuming herd immunity after only 80% infection. 95% would be a better/more reasonable estimate.
PPS - luckily, Sweden never even came close to the percentages they needed for immunity in the “first wave”.
