Findings from a new study suggest that the COVID-19 rebound is not caused by an impaired immune response. The study, which is currently being conducted by a team of researchers at the University of California, Los Angeles (UCLA), is still ongoing and has not yet been peer-reviewed. However, the findings suggest that people who experience a COVID-19 rebound are not more likely to have an impaired immune response than those who do not experience a rebound.
The study is based on data from two clinical trials that were conducted in China. The first trial included people who had recovered from COVID-19 and then experienced a rebound, and the second trial included people who had never had COVID-19. The researchers analyzed blood samples from both groups of people to see whether there were differences in their immune responses.
The results showed that there were no significant differences in the immune responses of people who experienced a COVID-19 rebound and those who did not. This suggests that the COVID-19 rebound is not caused by an impaired immune response.
The findings from this study are preliminary and more research is needed to confirm them. However, if the findings are confirmed, it could have implications for how we treat people who experience a COVID-19 rebound. Currently, many people who experience a rebound are treated as if they have an impaired immune response, but this study suggests that this may not be necessary.

(CNN) — Scientists have long suspected that people who catch COVID-19 and recover may be susceptible to catching it again.
Now, new research adds credence to that idea, but not for the reason you may think.
A group of researchers in China found that people who had been infected with the coronavirus and then recovered had a “robust” immune response when they were reinfected with the virus, according to a study published in the journal Nature Medicine on Monday.
But, even though they had a strong immune response, they were still just as likely to get sick again as people who had never been infected before.
The findings suggest that the immune response alone is not enough to protect people from catching COVID-19 a second time and that other factors, such as the amount of virus a person is exposed to, may play a role in whether someone becomes sick.
The researchers looked at 101 people who were reinfected with COVID-19 and found that their bodies produced more antibodies against the virus than people who had never been infected before.
“Our data suggest that, although both primary and secondary infections induce robust antibody responses, these responses are not necessarily protective,” the authors wrote in the study.
The findings add to a growing body of evidence that suggests people who have recovered from COVID-19 may be susceptible to catching it again.
Several studies have found that people who have been infected with the coronavirus and then recover may have a lower level of immunity than people who have never been infected before.
And, a small study published in the journal Nature last month found that people who had recovered from COVID-19 and then were reinfected with the virus had a “significantly attenuated” immune response.
The new study is the first to look at the immune response in people who have been reinfected with the coronavirus and provides more evidence that the virus can cause a “rebound” infection in people who have recovered from it.
However, the findings do not necessarily mean that people who have recovered from COVID-19 are more likely to catch it again.
The authors of the new study cautioned that the findings need to be confirmed in a larger study and that more research is needed to understand why some people who have recovered from COVID-19 may be susceptible to catching it again.
