COVID-19 Vaccination and Estimated Public Health Impact in California.

ABSTRACT:

Importance

Despite widespread vaccination against COVID-19 in the United States, there are limited empirical data quantifying their public health impact in the population.

Objective

To estimate the number of COVID-19 cases, hospitalizations, and deaths directly averted because of COVID-19 vaccination in California.

Design, setting, and participants

A statistical model was used to estimate the number of COVID-19 cases that would have occurred in the vaccine era (November 29, 2020, to October 16, 2021) in the absence of vaccination bas
