Around December 20th the infection rate among fully vaccinated adults has increased by 556% and by 179% among the unvaccinated.
This is a sharp shift in the trend, away from an approximately double infection rate among the unvaccinated against vaccinated for a long period. For those with a booster the shift is even bigger, 1200%.
What might be the explanation for this? Is there a reason to expect a surge in hospitalisations among the vaccinated will follow?
