Homophobia in the provision of sexual health care in the UK.

Decision making in the provision of health care is influenced by not only scientific evidence but also by the systems in which decisions are made. We consider national decisions made in the UK related to sexually transmitted infection prevention in gay, bisexual, and other men who have sex with men (GBMSM), with three specific examples-HIV pre-exposure prophylaxis, mpox (formerly known as monkeypox) vaccination, and doxycycline prophylaxis. We suggest that entrenched societal and political homophobia results in unacceptable delays and limitations to accessing highly effective interventions and that these delays result in harm from preventable transmissions of HIV, mpox, and syphilis. GBMSM have been affected disproportionately by HIV, mpox, and bacterial sexually transmitted infections, and there is an ongoing unmet need for effective prevention. Denying access to public health interventions that meet these needs is unethical.
