Data supporting "Temporal trends of SARS-CoV-2 exposure in adolescents: a longitudinal pilot study nested in a Uganda birth cohort"

Data were drawn from three studies that these participants took part in, where samples were collected: pre-pandemic samples (2014–2016) collected during a blood pressure study; pandemic-era samples collected during the POPVAC C trial (2020–2021) (ISRCTN32849447), which evaluated the impact of BCG revaccination on vaccine responses; and samples from the CoHost study (2021–2022), a 12-month longitudinal follow-up assessing SARS-CoV-2 infection and exposure from participants in the POPVAC B randomised controlled trial.

The study aimed to analyse temporal trends in SARS-CoV-2 seropositivity in Ugandan adolescents using pre-pandemic (2014-2016) and pandemic-era samples (2020-2022). We utilised previously stored demographic and clinical data, along with bio-banked samples from these three studies.
