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.

Avoiding antibody-dependent enhancement enables dengue prevention and treatment

Dengue virus is one of the most widespread vector-borne viral pathogens in the world. Nearly 400 million dengue virus infections occur each year, resulting in approximately 20,000 deaths.

Chronic interferon exposure drives immunosuppression in tumors

Cancer biology and, in turn, cancer treatment have come a long way in the last few decades. Most people recognize this progress in breakthroughs like immunotherapy-a treatment strategy first deployed in 2011 that leverages the body's own immune cells to fight cancer and revolutionized the treatment landscape.

Weakened form of Mpox drove the 2022 global outbreak

The strain of Mpox behind the 2022 outbreak was a weakened form of the virus, which may have helped to spread it faster, a new study from the University of Surrey reports.

Updated COVID-19 vaccines protect adults with autoimmune rheumatic conditions

In an Arthritis & Rheumatology analysis of data on 60,980 US adults with autoimmune rheumatic conditions who developed COVID-19 between December 2020 and August 2024, those who received booster or updated (2023-2024) COVID-19 vaccines were less likely to be hospitalized for COVID-19 compared to those who received only the initial series vaccines or who were unvaccinated.

COVID-19 linked to lower subsequent risk of type 1 diabetes

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) shows that people who have had COVID-19 have a lower, rather than higher, risk of subsequent development of type 1 diabetes (T1D).
