BOSTON: Children who have been exposed to Covid 19 before, that is mild coronary disease or severe coronary disease, are more likely to be re-infected with various mutations in the omecron. One study found that if they were vaccinated, they would be relatively protected against omecron.
The findings are published in the journal Nature Communications. These results are similar to those of adult studies.
The children have previously been infected with coronaviruses, which have been unable to destroy the antibodies that the omecron has produced in their bodies to kill the virus. This means that children who have not been vaccinated are at higher risk of contracting omecron. The study, conducted by the US Food and Drug Administration, collected blood samples from 62 children with severe coronary heart disease. The study also examined blood samples from 50 outpatients who had mild corona, including 65 children who had severe coronary artery disease (MIS-C). These blood samples were taken between 2020 and early 2021, before the coronavirus mutated to omecron.
In the lab, the researchers screened these blood samples for mutations in the alpha, beta, gamma, delta, and omecron variants of the crown. These mild strains of the SARS-Cove-2 virus were grown in the laboratory. Some of the antibodies in the blood samples of children and adolescents were destroyed by neutralizing these five types of corona. However, the neutralization of ‘Omaicron’ increases the rate at which these antibodies are destroyed.
Omycron differs from the previous types of crown. Due to the many mutations in its spiny protein coat, it has been shown that it can fight off antibodies efficiently. However, in children who have completed both doses of the vaccine, the antibodies in their blood samples neutralize all five types, including the coronary omecron. Therefore, children who have had coronary heart disease but have not been vaccinated are more likely to be re-infected with omecron. Now, looking at these findings, the researchers hope that parents will vaccinate their children as much as possible.
