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.

The 0.05 EU/mg breakthrough: How Sino Biological ProPure™ is redefining the Ultra-Low Endotoxin standard

When we discuss bacterial infections, we often think of exotoxins—those soluble proteins actively secreted by bacteria—while overlooking endotoxins, which are more insidious but equally dangerous.

Scientists uncover how the immune system actively builds food tolerance

Food allergies are serious and, for some, potentially deadly. And yet, despite decades of research into allergies and what causes them, very little is known about why the vast majority of people are able to tolerate foods that can sicken or even kill others.

DNA origami vaccine platform shows promise against multiple infectious viruses

The COVID-19 pandemic brought messenger RNA (mRNA) vaccines to the forefront of global health care. After their clinical trial stages, the first COVID-19 mRNA vaccine was administered on 8 December 2020 and mathematical models suggest that mRNA vaccines prevented at least 14.4 million deaths from COVID-19 in the first year alone.

New peptide fragments teach the gut to tolerate food

In little moments like when sipping coffee or licking an ice cream cone, it doesn't seem like your body is pulling off a biological miracle. But it is. That cookie is not you-yet when you put it in your mouth, your body is able to tolerate it and process it without any detriment to your health in a process called oral tolerance. How does the human body make that decision between tolerance and rejection?

AI pinpoints why vaccine responses vary globally

How people with compromised immune systems respond to vaccines is an important area of immunological research. A new study led by York University found that not only could machine-learning models accurately pinpoint differences in healthy controls and those living with HIV, but also found outliers in both groups that provide fascinating glimpses into the complex nature of the immune system and what personalized medicine could look like in the future, accounting for variables such as age, comorbidities and genetics.
