From a recent editorial from a Johns Hopkins professor addressing the CDC trying to whitewash their own failings in the study:

"Yet the CDC spun the report to fit its narrative, bannering the conclusion “vaccination remains the safest strategy.” It based this conclusion on the finding that hybrid immunity—the combination of prior infection and vaccination—was associated with a slightly lower risk of testing positive for Covid. But those with hybrid immunity had a similar low rate of hospitalization (3 per 10,000) to those with natural immunity alone. In other words, vaccinating people who had already had Covid didn’t significantly reduce the risk of hospitalization."
"Similarly, the National Institutes of Health repeatedly has dismissed natural immunity by arguing that its duration is unknown—then failing to conduct studies to answer the question. Because of the NIH’s inaction, my Johns Hopkins colleagues and I conducted the study. We found that among 295 unvaccinated people who previously had Covid, antibodies were present in 99% of them up to nearly two years after infection. We also found that natural immunity developed from prior variants reduced the risk of infection with the Omicron variant."
Classic NIH:
Say there isn't enough data when challenged on a policy, then deliberately not study it. They did this for DECADES with cannabis.
