COVID-19 cytokine storms may prevent a durable immune response.

Shiv Pillai, MD, PhD, investigator in the Ragon Institute of MGH, MIT and Harvard and professor at Harvard Medical School (HMS), recently published a paper in Cell showing that high levels of some cytokines seen in COVID-19 patients, as part of a cytokine storm, may prevent the development of long-term immunity to SARS-CoV-2, the virus that causes COVID-19.

“We’ve seen a lot of studies suggesting that immunity in COVID-19 may not be durable because the antibodies decline over time,” says Pillai. “More telling for us was that in patients with both mild as well as severe disease, asntibodies lacked a key structural feature that is a hallmark of the ‘highest quality’ antibodies in a normal immune response. By using our understanding of how two different types of immune cells normally collaborate to make the best antibodies, we were able to find a mechanism that could explain this lower-quality immune response in COVID-19 patients.”

Simply put: Those that have the severest Covid-19 symptoms may not develop the, very desirable, T cells that provide long lasting immunity.

In essence, A good immune response does not necessarily mean long-lasting immunity. Unfortunately, vaccine manufacturing only measures immune response, not long-lasting immunity.

Cytokine storms are an over reaction of the immune system, they overproduce Neutrophils which remain immature. Hardly what you would call a good immune system.
