article in last couple days from Sweden: according to the leading health official, the country has only been able to “allow” less than 15% of the population to be exposed.
Most infectious disease doctors believe that a minimum of 60-70% of a population needs to be exposed to reach herd immunity
What is correct is that Sweden did not impose any restrictions or lockdowns.....in the HOPES of getting herd immunity.
But the country is a LONG way from that at the moment
edit to add cut and paste from that article:
Sweden's Public Health Agency
last week released the initial findings of an ongoing antibodies study that showed that 7.3% of people in Stockholm had developed antibodies against COVID-19 by late April. Tegnell later described the study's figure as a "bit lower than we'd thought," adding that the findings represented a snapshot of the situation some weeks ago and he believed that by now "a little more than 20%" of Stockholm's population should have contracted the virus.
