Children, people aged over 70 develop highest levels of COVID-19 antibodies, study reveals

Children of pre-school and primary school age and people over the age of 70 develop the maximum percentage of novel coronavirus antibodies, scientists from the St. Petersburg Pasteur Research Institute of Epidemiology and Microbiology found out during a large-scale research on COVID-19 herd immunity conducted in more than 20 Russian regions.

"In the overwhelming number of regions, the maximum level of the immune layer is observed in children’s groups, that is, pre-school and primary school age, followed by people aged 70 plus. When we conducted the study, we were prepared for the fact that, on the contrary, we will get the minimum level of the immune layer among those aged over 70. However, it turned out that this was not the case," Director of the Institute, member of the Russian Academy of Sciences Areg Totolian, told TASS on Friday.
