Oct 8 (Reuters) - The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that have yet to be certified by peer review.

Delta variant does not appear to make children sicker

The Delta variant of the coronavirus does not appear to cause more severe disease in children than earlier forms of the virus, a UK study suggests. Earlier this year, the research team found the Alpha variant of the virus did not appear to make children sicker than the so-called wild, or original, form of the virus, first seen in China. New data suggests that kids also do not get any sicker from Delta than they did from Alpha. ...

"Although we are seeing more cases in children ... these studies demonstrated that there was not increased disease severity in children," CDC Director Dr. Rochelle Walensky said of the Delta-driven wave in a statement. "More children have COVID-19 because there is more disease in the community."...

Secondary immune response stronger after infection than vaccination

An COVID-19 survivors, important components of the body's immune response called memory B cells continue to evolve and get stronger for at least several months, producing highly potent antibodies that can neutralize new variants of the virus, a new study has found. By comparison, vaccine-induced memory B cells are less robust, evolving for only a few weeks and never "learning" to protect against variants, researchers reported in a paper published on Thursday in Nature. ...
