Note, it says that fully vaccinated workers carry 251 times the viral load for the delta variant compared to the prior variants. It isn't comparing vaccinated to unvaccinated.
Viral loads of breakthrough Delta variant infection cases were 251 times higher than those of cases infected with old strains detected between March-April 2020.
What's more interesting is:
There was no correlation between vaccine-induced neutralizing antibody levels and viral loads or the development of symptoms.
The jab neither reduces the spread, nor does it reduce the likelyhood of developing symptoms for the now dominant Delta variant.
