PURPOSE OF REVIEW: Although current treatment could eradicate vertical transmission, in 2022, 130 000 infants acquired HIV globally. HIV suppression with antiretroviral therapy (ART) transforms survival for people living with HIV (PLWH), and prevents transmission, including vertical. International guidelines recommend lifelong ART for PLWH, consequently perinatal HIV acquisition reflects implementation gaps in the HIV care cascade. We summarize these gaps, exploring potential novel approaches and therapeutic innovations towards eliminating vertical HIV transmission. RECENT FINDINGS: Multifactorial challenges continue to underpin gaps in the HIV care cascade, including accessibility, availability and sustainability of HIV testing, prevention and treatment, alongside stigma, gender-based violence and poverty. Long-acting ART may be important in preventing perinatal HIV acquisition, with early data demonstrating tolerability and efficacy of injectable ART throughout pregnancy, both as HIV treatment and prevention. Carefully selected long-acting broadly neutralizing antibodies (bNAbs) matching circulating, exposing viral envelope sequences have demonstrated safety, clinical trials are ongoing to demonstrate efficacy. SUMMARY: Emerging clinical studies should prioritize pregnant/lactating people and infants to ensure such therapies are well tolerated and efficacious. Alongside therapeutic innovation, programmatic strategies must address social and economic challenges, ensuring sustainable HIV treatment/prevention programmes and facilitating global elimination of blood-borne viruses.
