So far most deaths from the vaccine occur during the first two weeks. To blame these deaths on the lack of vaccination instead of on the vaccine, the CDC rules that you are not actually vaccinated until two weeks after having the second injection.
The CDC defines a "vaccine breakthrough infection" as "the detection of SARS-CoV-2 RNA or antigen in a respiratory specimen collected from a person 14 days after they have completed all recommended doses of the Food and Drug Administration authorized Covid-19 vaccine."
This is one of the tricks the corrupt "public health agency" uses to scare people about Covid and use fear to drive them to inoculation.
Another trick, already much reported, is to run the PCR Covid test at 40 cycles which guarantees as much as 97% false positives. This deception is the source of the scary number of "Covid cases."
