A few numbers that may show why the herd immunity approach isn’t politically viable.
To obtain herd immunity, 60-80% of a population needs to be immune.
Best estimate so far on Covid-19 mortality rate is 0.66%
Because I’m an optimist, I will use 60% and 0.5%.
In 1 million people, we need 600,000 infected. Of these, 3000 will die.
I Norway with 5 million people, that means 15,000 dead.
In a normal year, 41,000 people die. That is over 35% Increase. Some of the 15,000 would have died anyway, but 30% over a normal year does not look good.
Those 15,000 Norwegians would be 900,000 Americans or 4.2 million Chinese.
Herd immunity isn’t a realistic goal, even when you are an optimist like me.
