Asymptomatic or mild symptomatic COVID-19 elicits effective and long-lasting antibody responses in children and adolescents

A study from Duke University published in the Journal of Clinical investigations Asymptomatic or mild symptomatic SARS-CoV-2 infection elicits durable neutralizing antibody responses in children and adolescents showed that children who had the COVID-19  who had few or no symptoms could develop immunity that lasted for months.

The study showed that mildly infected children developed several types of antibodies, namely IgM, IgG, and IgA, at the time of infection. These antibodies are necessary for the body to defeat the infection.

Not only that, the antibodies are effective at neutralizing or completely getting rid of the SARS-CoV-2 and can still be detected 4 months after the infection in the overwhelming majority of children and teenagers. The authors can only conclude up to four months because that is the duration of the follow-up. The immunity can be potentially much longer.

The antibodies are so effective that they are comparable or better to those seen in adults who had a mild infection.

The results of this study are significant for the coming opening of the school year.

Hopefully, the policymakers will listen to the science and make policies that will benefit the children.
