None dare call it vaccine failure. CDC just calls it lower VE, vaccine effectiveness.
It's buried in paragraph 10:
During April 4–June 19, fully vaccinated persons accounted for 5% of
cases, 7% of hospitalizations, and 8% of deaths overall; these
percentages were higher during June 20–July 17 (18%, 14%, and 16%,
respectively).
Using the reported 37% vaccination coverage for the 13
jurisdictions during April 4–June 19 and an assumption of 90% VE,
vaccinated persons would have been expected to account for 6% of cases
(close to the 5% observed). With 53% coverage reported during June
20–July 17, vaccinated persons were expected to account for 10% of cases
at a constant VE of 90%; the observed 18% would have been expected at a
lower VE of 80%.
So as the vaccines wear off, even though you have increased vaccine coverage in the interim, meaning the percentage of the population vaccinated has increased, you get more breakthrough cases, more hospitalizations, and more deaths than you would earlier with less "coverage" because vaccine effectiveness was previously stronger.
In other words, the absence of breakthrough cases early in the mass vaccination effort was simply an illusion, an artifact of not enough time having passed for the VE to decay.
CNN reports the sad story of a 66 year old immunocompromised mother who died of COVID-19 in early September even though she was fully vaccinated in March. She had traveled to Mississippi in July. In her obituary her family blames the unvaccinated in Mississippi for her death.
That's appalling, because waning vaccine effectiveness is to blame, along with her misplaced faith in the vaccines, derived from the 24/7 propaganda sales campaign of the CDC, the federal government and the medical establishment, which have whipped up an hysteria about getting vacccinated to avoid a serious outcome, an outcome which it is increasingly clear this vaccine cannot provide over the long haul.
That's why the booster shot is being teed up.
But the way this is going, you are going to need a booster every few months for the damn thing to do you any good.
And at this point no one knows whether that will be dangerous or not.
But know this. The Powers That Be have heard the objections at the FDA that the most serious side effects to the vaccines come after the second shot. What will happen after a third? A fourth? A fifth?
They do NOT KNOW.
The vaccines do not make you bullet-proof. The vaccines wear off. And your misplaced faith in them means you can spread the virus asymptomatically, as the July 4 study in Provincetown showed, and eventually you can become more vulnerable to getting COVID-19 yourself.
