Fully vaccinated people have made up as few as 0.1 percent to as many as 5 percent of COVD-19 hospitalizations in some states since the start of the U.S. vaccination campaign, according to an Aug. 11 analysis from The New York Times.
The analysis is based on data from 40 states and Washington, D.C., which shared information on breakthrough hospitalizations and deaths with the Times. The news outlet began collecting data at the start of the vaccination campaign, and many states stopped providing breakthrough data through June or July, which may not reflect the ongoing surge of delta variant infections, the methodology notes.
Here are breakthrough hospitalizations and deaths, presented as a percentage of all COVID-19 hospitalizations and deaths in each state:

Connecticut, Hawaii, Maryland and Wyoming were excluded from the analysis because they provided less than two months of data. Iowa, Missouri and Pennsylvania told the Times they could not provide breakthrough data because their own systems didn't effectively track them. Florida, Kansas and New York did not provide any data.
