A study illustrates how SARS-CoV-2 can damage your immune response
Because researchers took multiple blood samples from the volunteers over the four-month study, they were able to delve deeper in how the T cell populations were changing, and confirmed the pattern. Vaccinated people who had not had COVID-19 generated CD8 T cells up to 67.1-times higher than they did before they got the shots. While people who had recovered from COVID-19 and then got vaccinated also produced higher levels compared to baseline, these were anywhere from 3.
Researchers don’t yet know what a weaker CD8 response against SARS-CoV-2 means for a person’s health. But the study also showed that people in this group still benefited from the vaccine—just not as much as those who hadn’t been infected before getting it. Levels of CD8 cells among those who had infections and then were vaccinated were still higher than levels among unvaccinated people.
Given these findings, can repeated COVID-19 infections continue to dampen the T cell response, and increase the likelihood of Long COVID or worsening symptoms? It’s possible, since experts believe that the T cell response is responsible for the more durable protection that keeps people from experiencing severe disease resulting in hospitalization or death. But that question, too, remains unanswered.
