PrEP-LANA (Pre-exposure Prophylaxis- Long-acting Novel Antiviral Agent)

The goal of this 12-month implementation science study is to generate the evidence required to ensure long-acting cabotegravir (LA CAB) as pre-exposure prophylaxis (PrEP) can be delivered in an equitable manner within the NHS. This study will recruit both PrEP users and healthcare professionals (HCPs). The main questions it aims to answer are: * What do healthcare providers think about the feasibility of delivering LA CAB PrEP within sexual health services in the NHS? * How many participants stay on/remain consistent with LA CAB PrEP injections at Month 12 (PrEP persistence)? Participants (200 PrEP users) will be followed for 12-months and asked to complete surveys at 3 study visits. A subset of 20 participants will also be asked to complete interviews about their experiences. We will also ask 20 HCPs at participating locations to complete surveys and interviews at both baseline and month 12. A core principle of equity (understanding any difference in impact on underserved populations) will be applied throughout the study. To ensure representation of a diverse group of participants that reflects the demographic groups most affected by incident HIV and most underserved by PrEP in the UK, enrolment targets will be applied and meticulously managed by the central study team, as follows: * A cap of 30% (n=60) will be applied to recruitment of White cisgender men who have sex with men who are not otherwise part of other under-represented groups (as defined below), * At least 70%% (n=140) of participants will represent groups currently underserved by PrEP and fall into one (or more) of the following socio-demographic categories: women (defined cisgender or transgender) OR as transgender men OR non-binary individuals OR age\<25 yrs, OR sex workers OR people who inject drugs OR racially minoritised heterosexual men.
