Oh please! The medical community is proving itself to be one of the worst sorts of advisers - the idiot-savant whose only tool is a hammer, so every problem becomes a nail.
First off, covid didn't take millions of lives, and "effective vaccines" didn't substantially reduce that number. The total excess deaths for 2020-2022 is not very high, which means that, to the extent a death can be attributed on a causal basis to covid-19, it generally only replaced a death that would have been attributable to influenza, or to heart failure, or to some other gross comorbidity.
Secondly, the vaccines are proving themselves to be of only marginal benefit, and certainly not nearly as effective as natural immunity.
Thirdly, the most telling point is the point the medical industry consummately refuses to address: infections may be going up, but cases of serious symptoms, hospitalizations, or death, are not, for the simple reason that this virus - like every other virus in the world - has evolved to be more infectious and less virulent.
It is not going to suddenly reverse course and evolve into the next Marburg or Ebola, for the simple reason that its primary host pool is the human species, and becoming more virulent would deprive it of the hosts needed to sustain itself. Marburg and Ebola can continue to remain as virulent as they are because their primary host pool is not humans, but certain animal species.
The medical industry needs to learn to STFU and stop treating every little molehill as if it was an existential threat to the entire human species.
