Study links severe COVID to higher TB risk, and vaccination appears to blunt the link

A nationwide Chilean cohort study of more than 3.6 million adults found that severe COVID-19 requiring hospitalization was associated with more than an eightfold higher hazard of incident tuberculosis within one year. The association was strongest in the first six months and among unvaccinated individuals, although absolute TB incidence remained low.

Botanical prebiotics may steer skin microbes toward healthier balance

Researchers tested plant-derived prebiotic candidates against selected skin-associated bacteria and found that garlic, flaxseed, and mango ginger extracts inhibited S. aureus or acne-associated C. acnes in vitro. Onion and guduchi extracts modestly promoted S. epidermidis, suggesting a microbiome-targeted skincare route that now needs validation in skin models and human studies.
