Persistent identifier

10.17037/DATA.00003754

Description

A quantitative dataset containing information on COVID seroprevalence in pregnant women. Analysis was performed on samples collected from 803 women between October 2019 – March 2022 in Farafenni, North Bank Region of The Gambia. This is a sub-set of women in the PRECISE Study where pregnant women were recruited to the cohort and followed up during their pregnancy.

Data access method

To access the data, requests must be made to the P.I. in The Gambia. The request will be reviewed by both the Gambian Team and the PRECISE Consortium Data and Sample Access Committee, which consists of the leads of all the collaborating units as well as a panel of experts. The committee will review the request based on scientific value and to ensure there is no overlap with existing work. If the study is approved, before data is shared, ethics approval will need to be obtained in both The Gambia and in your host institution as well as Data User Responsibilities Agreements being signed.
