Children's 'rushed' immune response makes them susceptible to Covid reinfection: Study

Melbourne, Jan 27 (PTI) Scientists have found that children's immune systems, unlike those of adults, do not remember the virus and do not adapt, and so when exposed to SARS-CoV-2 again, their body still treats it as a new threat, risking reinfection.

According to the study, children have largely avoided severe COVID-19 symptoms because they have a strong initial 'innate' immune reaction that quickly defeats the virus.

And now, researchers led by scientists at the Garvan Institute of Medical Research, Australia, have uncovered what this might mean for the immune system, the study published in the journal Clinical Immunology said.
