Pandemic Data Outlook

Private Institutions Pioneer COVID-19 Data Sharing

From the start of the pandemic, Johns Hopkins University and some media organizations recognized that the national public health infrastructure was not well equipped to track COVID-19 data in near real time. These data pioneers rose up to provide the public and policymakers with high-quality, trustworthy information to help keep people safe and inform critical decisions.

Pandemic Data Outlook

States and CDC Improve Breakthrough and Booster Data Reporting

Since authorization of COVID-19 vaccines, data on breakthrough cases and booster doses have been essential to tracking vaccine efficacy and coverage levels, and identifying unvaccinated or undervaccinated populations. The CDC now reports cases and deaths by vaccination status and states are consistently reporting booster doses.
