This is an amazing story, only half told so far.
The herd-like promotion of the vaccines, treating unequal risk groups equally, is easy to understand as bureaucratic “follow the leader”.
And the beginnings, in December 2020, are easy to understand based on overgeneralization of the Pfizer and Moderna Phase II results.
What is hard to understand, and becoming very hard to understand, is the persistent pressure from the top to treat these vaccines as if most of the data collected since launch does not exist.
For example: Who decided that licensing down to 6 months of age would be desirable?
The leadership - the very top leadership - of the public health and international (Western) political establishments were spooked by something about the virus that has not been revealed or discovered yet, and their continued fidelity to age-and sex-unrestricted population vaccination makes it look to me like they are still running scared.
Or they just saw it as a golden opportunity to test planned tactics for the Great Reset and figure out how completely the public would be willing to obey. Judging by the results they achieved, I suspect they feel the test was a big success.
