The 3 US vaccines and their residual efficacy after just a few short months, per the VA

From today’s WaPo, a preliminary report from the VA on 620,000 veterans (not 2.7%  but 0.19% of the US population) and the waning benefit of their vaccinations:

Using data from the Veterans Health Administration, the largest health system in the United States, researchers compared coronavirus infections by vaccination status among 620,000 veterans — representing 2.7 percent of the U.S. population — from Feb. 1 to Aug. 13.

Although the report has yet to be peer reviewed and evaluated, it indicates that virus immunity decreased over time and that its decline was different for each of the three vaccines available in the United States.

According to the study, the greatest waning was presented by the Johnson & Johnson product, with protection falling from 88 percent in March to 3 percent in August. In the same period, it declined for the Pfizer-BioNTech vaccine from 91 percent to 50 percent. For Moderna, protection fell from 92 percent to 64 percent.

They concluded that protection against infection for the J&J shot declined to 3% by August. THREE PERCENT. I hope no one got an adverse reaction for that much protection.

They also seem to be saying that it's mainly Delta causing the breakthroughs, and not the time passed from getting shot. No one should be getting J&J, and with the others people are definitely going to get infected.
