Presumably, this would imply to me that a third dose/booster would bump 2x vaccinated to similar levels of nAbs as the vaccinated
NACI GUIDANCE FOR USE IS INCLUDED BELOW Dose schedule NACI recommends two 10 mcg doses of the Pfizer vaccine may be offered to children 5-11 years of age, with at least 8 weeks between the first and second dose.

This post was created in collaboration with Dr. Elisabeth Marnik This new preprint, while small in numbers, does a fantastic job of outlining the immune response that occurs in breakthrough infections. A cluster of over 1000+ infections with Covid-19 delta variant were identified in a mostly fully vaccinated population in Provincetown, Massachusetts in July 2021.
