Explore Vaccination Progress by U.S. State
With dozens of COVID-19 vaccines now in clinical trials, it is important to understand the accelerated timelines for development, the different types of vaccines available, and the facts related to vaccine safety and efficacy. Additionally, as vaccines are approved, we will track data on vaccination efforts.
Explore how U.S. states delivered their supplies of COVID-19 vaccines to their residents at vastly different speeds that led to vastly different results.
An interactive tool from our vaccine experts that explores how a vaccine is developed and the differences between a typical timeline and an accelerated timeline.
VIEW-hub is a publicly available interactive tool that displays up-to-date information on vaccine characteristics, and vaccine introduction and use globally. Vaccines include COVID-19 as well as many childhood vaccines in routine immunization programs.
