The article says because of the virus itself. In the UK, conservatives blame excess deaths on their lockdowns... only a very few, like Mark Steyn, blame the vaccines.
I think if you look at 2020 - virus and no vaccine and later years, virus with vaccination, you will find excess deaths increased mostly after the vaccine was deployed.
We are also seeing greater rates of myocardtis especially in younger adults after the vaccine was introduced compared to pre-vaccine years. As the effects of vaccine manifest, we will see even more conclusive data on increases in cancer, immune related disease, cardiovascular disease.
The reason myocardtis popped out so quickly as an anomaly is because the pre-vaccine rate of myocardtis was so low in young people. CA and cardiovascular disease is much more prevalent so the increased death rate in older groups won’t be as pronounced as a percentage increase. But, because we’re talking about much a large group, the total number of excess deaths will likely be much greater.
Myocardtis is the canary in the coal mine and a harbinger of more deaths from common diseases in older populations.
