They never have, even at peak effectiveness. A huge US database offers proof

Even at the peak of their protection earlier in 2021, Covid vaccines barely reduced the risk of hospitalizations in vaccinated people who had “breakthrough” infections, new data show.

Vaccinated people in a study published Tuesday had a nearly 1 in 200 chance of of requiring hospitalization for Covid in the first six months after being “fully vaccinated.”

The data comes from a study of about 600,000 vaccinated Americans seen at over 100 academic medical centers.

The study was published online Dec. 28 in the Journal of the American Medical Association – JAMA Internal Medicine.
