Tshireletso: Safety, Efficacy and Feasibility of Cabotegravir-LA PrEP in a Breastfeeding Population in Botswana

The goal of this this hybrid safety/implementation study is to evaluate whether using long-acting cabotegravir (CAB-LA) for HIV prevention (PrEP) is acceptable, feasible and safe in post-partum people who are breastfeeding. The main question\[s\] it aims to answer are: * Will CAB-LA injections work well as a way to prevent HIV infection in post-partum people? * Will CAB-LA injections be safe in post-partum people and their infants who will be breastfeeding? Participants without HIV who are admitted to the maternity ward after having delivered a baby will be offered to start CAB-LA PrEP. Those who choose to participate will receive their first dose (injection) at the maternity ward and their follow up doses (injections) at their local clinic when they come for routine post-partum and pediatric care. Participants and their infants will be followed in the study for 24 months. We will be following how many people come on-time for their CAB-LA injections, how often they keep coming back, and the reasons they continue (or stop) these injections. We will also test people for HIV at all of their visits to see how many people get HIV during the study. We will also measure the levels of the medication in the blood of the post-partum people and their infants (who may be getting some of the CAB-LA in breastmilk) and evaluate to see if their is any impact of CAB-LA on the health of the post-partum person or their infants.
