(TELESUR) – Research shows that patient’s antibody levels drop significantly three months after infection.
After testing more than 90 patients and health care workers’ immune response, scientists found that antibodies capable of destroying the virus peaked about three weeks after the onset of symptoms, and then rapidly declined.
“People are producing a reasonable antibody response to the virus, although this decreases over a short period, so how high your peak depends on how long the antibodies remain,” the research’s author, Katie Doores, told The Guardian.”
Blood tests revealed that while 60 percent of people had a “potent” antibody response at the peak of their fight against the virus, only 17 percent maintained the same potency three months later. Antibody levels fell up to 23 times during the period and, in some cases, became undetectable.
