Natural COVID-19 antibodies persist for 7 months in children: Study

Study volunteers provided researchers with three separate blood draws. Samples were collected prior to vaccine deployment and in Delta and Omicron variants. To date, investigators have completed three different phases of the study.

“This is the first study from the Texas CARES survey to include data from all three time points in the survey,” said Sarah Messiah, PhD, MPH, the study’s respective author and professor of epidemiology. science, human genetics and environmental science at UTHealth. Dallas Campus School of Public Health. “These findings are important because the information we collected from children infected with COVID-19 did not differ at all in terms of whether children were asymptomatic, the severity of their symptoms, when they were infected with the virus,” said Dr. -withdrawal, healthy weight or obese, or by gender. Everyone is the same.”

The Texas CARES results are just one step toward understanding the impact of the virus on children, Messiah said. To date, 14 million children in the US have tested positive for the virus, she said.

“The adult literature shows us that natural infection, plus vaccine-induced protection, gives you the best protection against COVID-19 and doesn’t need it. Vaccination Although our research is encouraging that some natural antibodies persist for at least six months in children, we do not yet know the absolute threshold of protection. Great to give kids extra Messiah speaking.
