This seems intuitively off to me:

Their researchers have sifted through data and determined the vaccine appears to have protective qualities against COVID but loses them rapidly.

The benefit compared to the unvaccinated is 95 percent two weeks after the second dose, falls to 75 percent after 3 months, and to just 16 percent after 6 months. This would also suggest that after 7 months the benefit drops to nothing.

My guess is they are diluting these, perhaps to ~50% standard dose. The effect of doing so would be short lived immunity in a fraction of the recipients, and lower rate of severe adverse effects in general.
