The obervation came from a recent paper from Australia which was widely misquoted and consisted of only seven children during the pre-vaccine era.
Healthy children are able to get rid of the SARS-CoV-2 virus far easier than adults. That is because they have robust innate immunity.
A recent paper from Australia was widely misquoted, claiming that children are at greater risk of getting sick from repeated infections from the SARS-CoV-2 virus as they apparently failed to generate immune memory following a bout of COVID-19. This turns out to be an erroneous conclusion drawn from a small study of only seven children during the pre-vaccine era.
Human immune response to infection occurs in two stages. The first is called innate immunity, which refers to the immediate broad steps taken to eliminate the threat. The studied response that occurs afterwards is called adaptive immunity. The latter includes custom-made antibodies targeted against the virus and T-lymphocytes that help eliminate cells infected by the virus.
