We will not have as many deaths because we will have herd immunity by the time the other countries start to lift their lockdown which means the virus won't spread much more in Sweden, whereas you will have a higher number of cases and deaths. (sott.net)
In our new paper, we have created models which examine how changes in contact networks during lockdown affect the herd immunity level induced by the first wave of the epidemic. (sussex.ac.uk)
We found that if you consider the way patterns of contact change during lockdown, then actually the level at which disease-induced 'herd immunity' is reached is higher than the most optimistic estimates we have seen. (sussex.ac.uk)
In the models we studied, where 'herd immunity' was achieved at around 40 per cent when lockdown was implemented as a change in the probability of transmission, we found that if changes in contact patterns were used instead, then the level of herd immunity required to halt the spread of the virus increased by between 5 and 10 per cent - up to 45 or 50 per cent.

By doing so, they will turn the healthy into the sick, destroy their immune systems in the long run, delay herd immunity to this virus, and expose vulnerable people to a lurking epidemic for longer than it needs to be around - not to mention the risk of atrophy in having so many seniors locked down indefinitely. (theblaze.com)
What is also striking about these studies showing or implying cross-immunity from other coronaviruses is that it is yet another piece of evidence that this virus is not that novel and is similar to other coronaviruses, which we've dealt with for years. (theblaze.com)
Which is that once at least 60% of the population has become INFECTED with the virus then they would develop an immunity and thus no longer spread the virus onto the remaining 40% or so of the population. (marketoracle.co.uk)

This is the broader problem with the panicked response and how it will get more people killed by forestalling herd immunity. (theblaze.com)
But it is known that disease-induced 'herd immunity' happens at a lower rate than vaccine-induced 'herd immunity', partly because the most active and vulnerable people get infected first. (sussex.ac.uk)
