The "powers that be" created and maintain the database.
If they wanted to manipulate the data they would probably do it on the front end rather than having to go in and clean up after the fact.
Mistakes happen sometimes. Then the numbers must be "revised".
You can bet that this mistake won't happen again.
My personal estimate is that we have about 450,000 deaths caused by the mRNA treatment to date. They have been and will continue to be categorized as coincidental heart attacks, strokes, embolisms, and platelet destruction syndrome which have no connection with the jab that the patient received in the previous 30 days.
Note that over 200 million people in this country have received the treatment, so the estimated death rate is still very low. Not much comfort there for the families of the afflicted, but there it is.
Watch the life insurance companies and their shifting actuarial tables for the confirming indicators. Also follow the specialized industry journals which are studying death rates that are increasing at 25% more than expected (even accounting for the natural Boomer die-off). They are already hinting at the possibility of correlations with the mRNA treatment. No one will say that just yet.
It is younger people (25-60) who are seeing the higher-than expected increases. There is big money riding on getting these actuarial forecasts correct and they have usually been much more accurate than now. They have much more data than CDC and it is probably more accurate. And unbiased.
They will not allow themselves to lose big money on a politically correct narrative. They can buy, or at least rent, the necessary politicians to make sure they don't lose. Watch what they do.
