Breakthrough Cases

Last Updated: 09/17/2021

Vaccine breakthrough cases are expected. COVID-19 vaccines are effective and are a critical tool to bring the pandemic under control. However, no vaccines are 100% effective at preventing illness in vaccinated people.

Of the 512,701 fully vaccinated Delawareans, there have been 2,900 breakthrough cases of COVID-19, roughly 6 tenths of 1 percent.


The number of breakthrough cases and the number of fully vaccinated Delawareans are updated once per week on Fridays when the data becomes available, which may be after the rest of the data is published.
