Barbados has met the World Health Organization's targets for eliminating mother-to-child HIV transmission as a public health problem. WHO announced the validation on October 30 after an independent assessment.

No infant infections through that route were reported from 2022 through 2024. During the assessment period, antenatal care, HIV testing among pregnant women and treatment for pregnant women living with HIV each reached 98% coverage.

Testing and treatment are free for pregnant women regardless of nationality, with confidential, voluntary testing and follow-up for exposed infants.

The qualification matters: this is not the eradication of HIV, and continued care remains necessary. The achievement is a health system making prevention and treatment consistently reachable.

MIT researchers engineered a delivery platform from M13 bacteriophage, a virus harmless to humans. Its long, fibre-like structure can carry cancer antigens at controlled densities.

In the reported experiments, mice given a higher-density vaccine targeting a colon-tumour antigen were much less likely to develop those tumours. The work tested prevention in mice; it does not show that the approach cures cancer in people.

The attraction is modularity: researchers can exchange the antigens carried by the platform, potentially tailoring a future vaccine to a particular tumour.

Published October 30 in Advanced Healthcare Materials, the study adds an experimental tool to that effort. Whether it works safely and effectively for patients remains to be established.
