For those who haven’t heard of the Oregon Health and Science University, it is an elite, world class academic medical center at the forefront of clinical research located in Portland. I served as a Clinical Assistant Professor there in the early 2000s. It attracts some of the researchers in the world.
See this article about some very important research results just published by OHSU.

These results corroborate the observation that those who have had COVID previously benefit dramatically from getting vaccinated. We have known that for a long time. Hybrid immunity is best.
What this study suggests is something new, that immunity improves over time. This observation speaks to the role of cellular immunity and memory lymphocytes.
Much has been made of the decline of antbody titers after immunization by doctors of disinformation. They used that observation to mislead the public suggesting the vaccine benefit is short lived.
They are wrong
Why? None of the fake experts on FOX are actually immunologists. Their understanding of immunology is at a high school level. Ever heard any of them discuss B memory lymphocytes? I have. They decried the presence of spike protein in the germinal centers of lymph nodes as something negative. The opposite is actually the truth. By retaining antigen in the germinal center B memory lymphocytes, the immune system learns over time how to make antibodies against it.
