Individuals who recover from COVID-19 are protected against the virus for at least six months, probably much longer, suggests a new study published in the journal Nature. The study further indicates that the immune system continues to evolve long after the infection and may block even the virus variants such as the South African variant.

Investigators observed that antibodies produced by immune cells keep evolving, which could likely be due to sustained exposure to remnants of the virus in the gut tissue. The scientists state that this study has provided the strongest evidence so far that the immune system remembers the virus and continues to improve the quality of antibodies even after the infection dwindles… (HT – PTI, January 24, 2021)
