Integration of HIV pre-exposure prophylaxis (PrEP) services for pregnant and breastfeeding women in eight primary care clinics: results of an implementation science study

Although HIV vertical transmission has declined significantly in sub-Saharan Africa, incident HIV infection in pregnant and postpartum women is estimated to account for over one-third of HIV vertical transmission. Oral pre-exposure prophylaxis (PrEP) for pregnant and breastfeeding women (PBFW) is included in South African PrEP guidelines since 2021; however, integration of PrEP services within ante- and postnatal care remains limited.
