10.17037/DATA.00003755
A quantitative data containing information on COVID seroprevalence in pregnant women, based upon an analysis of 2,495 samples collected from 1,811 women between March 2020 – March 2022 in Kilifi County, Kenya. This is a sub-set of women in the PRECISE Study where pregnant women were recruited to the study and followed up during their pregnancy.
To access the data, requests must be made to the P.I. in Kenya. 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, Data User Responsibilities Agreements must be signed.
