More than 99.99% of people who are fully vaccinated against Covid-19 have not had a breakthrough case resulting in hospitalization or death, according to a CNN analysis of data from the US Centers for Disease Control and Prevention.
As of Aug. 2, more than 164 million people in the United States were fully vaccinated against Covid-19, according to the CDC. Fewer than 0.001% of those individuals — 1,507 people — died and fewer than 0.005% — 7,101 people — were hospitalized with Covid-19.
CDC last published data on breakthrough cases through July 26. These latest figures include 938 additional severe breakthrough cases — 862 additional hospitalizations and 244 additional deaths — reported over that seven-day period. The CDC does not provide more detail about the timing of the breakthrough cases.
About three-quarters (74%) of all reported breakthrough cases were among seniors age 65 or older. Of the roughly 1,500 people who died, one in five passed away from something other than Covid-19 even though they had a breakthrough case of the virus, according to the CDC.
Since May, the CDC has focused on investigating only hospitalized or fatal cases among those who have been fully vaccinated.
According to the CDC, this data relies on “passive and voluntary reporting” and are a “snapshot” to “help identify patterns and look for signals among vaccine breakthrough cases.”
“To date, no unexpected patterns have been identified in the case demographics or vaccine characteristics among people with reported vaccine breakthrough infections,” according to the CDC.
