TRIBUNPALU.COM – Recent studies have shown that the immune system that emerges after recovering from a Covid-19 infection can last up to five months, or more.
Reporting from CNN, October 29, 2020, the findings of this study are inversely proportional to the results of research from the UK which states that the immune system of patients recovering from Covid-19 can drop quickly.
The human body produces an army of immune compounds in response to infection.
In some people it becomes redundant, but will die quickly, and in others it accumulates more slowly.
This newly released study shows 90 percent of people who recover from Covid-19 infection maintain a stable overall antibody response.
“Several previous reports have suggested that antibodies to Covid-19 disappear quickly. However, we found to the contrary that more than 90 percent of people with mild or moderate symptoms produced antibodies that were strong enough to neutralize the virus and last for months,” said the study authors. , Florian Krammer.

“This is very important for the development of an effective vaccine,” he continued.
Researchers conducted antibody tests on more than 30,000 people who tested positive for Covid-19 from March to October 2020.
They found more than 90 percent developed moderate to high levels of antibody responses.
The study, published in the journal Science, also carefully analyzed 121 patients who recovered and donated their blood plasma.
