Two doses of Pfizer-BioNTech (BNT162b2) are 90% effective against COVID-19 hospitalizations for all variants, including delta, for at least six months, confirms a new study from Kaiser Permanente and Pfizer published in The Lancet

Effectiveness against all SARS-COV-2 infections declined over the study period, falling from 88% within one month after receiving two vaccine doses to 47% after six months. However, effectiveness against hospitalizations remained at 90% overall and for all variants.
