Covid-19 Vaccine Effectiveness in New York State.

ABSTRACT:

Background

Population-based data from the United States on the effectiveness of the three coronavirus disease 2019 (Covid-19) vaccines currently authorized by the Food and Drug Administration are limited. Whether declines in effectiveness are due to waning immunity, the B.1.617.2 (delta) variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), or other causes is unknown.

Methods

We compared cohorts defined according to vaccine product received, age, and month of full vaccination with age-specific unvaccin
