How Long Can the Official Covid Narrative Last?

In Israel most of the population has had the Covid shots. Mysteriously, there is a large outbreak of new Covid cases among the inoculated. 
.
With the assurances from the CDC and the rest of the Western World’s public health bureaucracies that the inoculations are 100% effective even for the Delta variant how can this be?  Here for example is the director of the CDC, Rochelle Walensky,
“If you are fully vaccinated you are protected against severe COVID, hospitalization and death, and are even protected against the known variants, including the delta variant, circulating in this country.”
 
The most likely explanation is that the new cases are the results of the inoculations.

The vaccines inject into the body the spike protein which is toxic. It causes Covid symptoms and more serious life-threatening illnesses.

Is there really a Delta variant or is it the cover story for the illnesses caused by the vaccines?
