The vaxxed are still getting covid. Your shot is worthless.
Of course it is.
Do the vaccines create a plastic air-tight bubble around the vaccinated person? If not it is low level common sense that nearby virus load will be inhaled by the vaccinated person. If the load is big enough, they could test positive.
Only difference between vaccinated and non-vaccinated is....
the vaccinated person’s immune system is already familiar with the protein signatures of the vaccine, and therefor much less likely to mount a over-the-top response of white corpuscles attacking the virus in lungs and that has resulted in permanent destruction of lung tissue. In addition, the vaccinated person has very good chance of anti-bodies present to fight the virus and reduce chance of death.
A mild exposure to the virus with minor symptoms acts similar to vaccine. Which is why shutdown of healthy people makes no sense.
