Kids formerly infected with COVID-19 establish natural flowing antibodies that last for at least 7 months, according to a brand-new research study led by researchers at UTHealth Houston.
The research study was published today (March 18, 2022) in Pediatrics.
Researchers analyzed data from 218 kids across the state of Texas between the ages of 5 and 19 who were enrolled in the Texas CARES study, which started in October of 2020 with the objective of assessing COVID-19 antibody status gradually among a population of grownups and children in Texas.
Volunteers who registered in the study provided scientists with three separate blood draws. Samples were collected before the vaccine rollout and throughout the Delta and Omicron versions. To date, private investigators have finished three various phases of the research study.
” This is the very first research study from the Texas CARES survey that includes information from all three time points in the study,” stated Sarah Messiah, PhD, MPH, corresponding author of the study and professor of public health, human genes, and environmental sciences at UTHealth School of Public Health Dallas campus. “These findings are essential because the information we collected from children infected with COVID-19 didnt differ at all by whether a child was asymptomatic, intensity of signs, when they had the infection, were at a healthy weight or had obesity, or by gender. It was the exact same for everyone.”
While 96% of those contaminated with COVID-19 continued to have antibodies approximately seven months later, well over half (58%) of the sample were negative for infection-induced antibodies at their third and last measurement. The findings do not include the impact of vaccine security.
The outcomes of Texas CARES, Messiah stated, are just an action in comprehending the infections effect on children. To date, 14 million kids in the U.S. have actually checked positive for the infection, she stated.
While our study is motivating in that some quantity natural antibodies last at least six months in kids, we still do not know the absolute security limit. We have an excellent tool available to provide kids extra security by getting their vaccine, so if your kid is qualified, take benefit of it,” Messiah stated.
The Texas CARES study is continuous.

“These findings are crucial since the info we gathered from children contaminated with COVID-19 didnt vary at all by whether a kid was asymptomatic, severity of symptoms, when they had the virus, were at a healthy weight or had obesity, or by gender. There has actually been a misconception from some moms and dads who think just because their kid has actually had COVID-19, they are now safeguarded and do not require to get the vaccine. While our research study is encouraging in that some amount natural antibodies last at least six months in children, we still do not understand the outright protection limit. We have a terrific tool readily available to give kids extra security by getting their vaccine, so if your child is eligible, take benefit of it,” Messiah stated.
