The CDC reported 6,587 Covid-19 breakthrough cases as of July 26, including 6,239 hospitalizations and 1,263 deaths.
At that time, more than 163 million people in the United States were fully vaccinated against Covid-19.
Most of the breakthrough cases — about 74% — occurred among adults 65 or older.
Since May, the CDC has focused on investigating only hospitalized or fatal Covid-19 cases among people who have been fully vaccinated. The agency says the 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.
Pace of vaccinations is going up
Amid concerns over the rising cases and the dangerous strain, the country has seen a steady rise in the pace of vaccinations in the past three weeks — and an even sharper increase in states that had been lagging the most, according to a Fintech Zoom analysis of CDC data.
The seven-day average of new doses administered in the US is now 652,084, up 26% from three weeks ago.
The difference is even more striking in several southern states: Alabama’s seven-day average of new doses administered is more than double what it was three weeks ago. The state has the lowest rate of its total population fully vaccinated in the US, at roughly 34%.
Arkansas, with just 36% of its population fully vaccinated, has also seen its average daily rate of doses administered double in the last three weeks.
