Yes breakthrough cases are also real, but far less common and usually much more mild. Plenty of data to prove it.
And sounds like De La Hoya will be just fine.
Why do the anti-vaxxers think covid is a hoax but only if the person in the hospital was vaccinated?
None of which you cite, of course. Not even one.
In May, the CDC reported that a super-spreader event had overrun a 74% "fully-vaccinated" Barnstable County, which is the whole of Cape Cod.
"In July 2021, following multiple large public events in a Barnstable County, Massachusetts, town, 469 COVID-19 cases were identified among Massachusetts residents who had traveled to the town during July 3–17; 346 (74%) occurred in fully vaccinated persons. Testing identified the Delta variant in 90% of specimens from 133 patients. Cycle threshold values were similar among specimens from patients who were fully vaccinated and those who were not."
Out of the 469 people who enjoyed Provincetown "activities" from July 3–17, 2021 and earned their COVID badge, exactly ONE UNVACCINATED PERSON WENT TO THE HOSPITAL FOR COVID. ONE.
And that ONE person had "multiple underlying medical conditions".
And DIDN'T die.
