Cedars-Sinai Hospital in Los Angeles is doing a large longterm study with Abbott Labs which checks antibodies in the blood of patients and staff there up to once monthly. Feedback is provided. I’ve received six months of results and find that just a few months after my third (Moderna bivalent omicron) booster, my antibodies were lower than they were even before that booster. Discouraging!

I wish they had such a study up here in the SF Bay area. I had my one and only J&J vaccine in Feb. 2021. My antibodies were > 250 in Feb. 2022 and "positive" in 2023. J&J vaccine starts out lower, but lasts longer than the others. FDA doesn't want to let the world know just how much longer. My antibody level could still be > 250, but the Kaiser test, done by Stanford Healthcare, doesn't report quantitative results for the general public, even though their machine has that information.
