It is essential to monitor the prevalence and changes in humorous defenses in kids and adolescents against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to explain the spread of the global epidemic and alert public health efforts like vaccination and school-based prevention programs.
Numerous serological tests were conducted to determine the number of antibodies at different phases of the global epidemic and to find SARS-CoV-2 illnesses in kids and teens.
In the current study, researchers looked at how humoral immunity developed over time in kids and teenagers throughout the COVID-19 pandemic.
Randomly chosen primary schools in the canton of Zurich were invited, as were the 2nd schools that were nearest to them in terms of distance. Out of the 156 invited schools, both public and private schools—nearly 55 accepted the invitation to take part.
Grades 1 to 2 were assigned to lower school, grades 4 and 5 to middle school, and grades from 7 to 9 to upper school. These courses were randomly chosen and assigned to one of 3 strata based on school level.
