According to a new, small study, newborns have a strong immune response to the virus that causes COVID-19.
For the study, researchers assessed the immune systems of four infants under 3 months of age who had recovered from COVID and compared them with adults who had also recovered from the disease.
Compared to adults, children produced relatively high levels of antibodies to immune cells that could specifically protect against the SARS-CoV-2 virus.
It is possible that this is why children seem to be able to avoid COVID-19 at a time when they are expected to be more vulnerable, according to the authors.
“In a detailed study of young infants who are relatively protected against severe COVID-19, we showed how protective immunity ‘looks’ for SARS-CoV-2-specific antibody-forming immune cells,” he says. The author of the study, Dr. Anu Goenka, is a clinical lecturer at the Royal Bristol Children’s Hospital, University of Bristol.
“This is very useful information for the design of future COVID-19 vaccines that may attempt to induce and mimic the signature of this protective immunity,” he said in a press release from the university.
The results were recently published in the journal Mobile reports medicine.

Children are much less likely than adults to develop COVID-19 during an epidemic. This was unexpected, especially in young infants who are vulnerable to other serious illnesses such as the RSV (respiratory syncytial virus) and influenza, the researchers said.
They said little was previously reported on the immune response of young infants to SARS-CoV-2.
There is more information about COVID-19 in infants and children at the Mayo Clinic.
