Vaccine

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

Analyzing the disparity between youth and adult HPV uptake

Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide and can cause various types of cancer. Prophylactic HPV vaccination is highly effective and has been recommended in Switzerland since 2007 for girls and young women aged 11 to 26 – and since 2015 also for boys and young men. Catch-up vaccination is also available for women up to the age of 45.

CDC tracks SARS-CoV-2 BA.3.2 global rise and finds early signals in U.S. wastewater

CDC surveillance shows that the highly divergent SARS-CoV-2 variant BA.3.2 spread to at least 23 countries and was detected in U.S. travelers, patients, airplane wastewater, and wastewater samples across multiple states. The report highlights wastewater and traveler-based genomic surveillance as early warning tools while noting that BA.3.2 has immune-evasion potential but has not rapidly displaced other circulating lineages.

Nepal and Afghanistan show how abrupt aid cuts can unravel essential care

Abrupt cuts to external health aid can destabilize multiple essential services simultaneously in fragile, donor-dependent settings, as illustrated by Nepal and Afghanistan. The paper argues that donor withdrawal is not just a resilience test, but also an ethical and governance issue that should be managed through “transition discipline.”

WHO urges faster TB detection with new point-of-care tests

On World TB Day, the World Health Organization (WHO) is urging countries to accelerate action to end tuberculosis (TB) and expand access to lifesaving services by using new innovations such as diagnostic tests that can be used near the point-of-care and tongue swabs that can help detect the disease faster reaching more people.
