Dietary supplements claim to be able to ‘boost your immune system’ to combat disease. But attaining immune balance through a healthy lifestyle and vaccination is a safer bet to keep in good health.

Seizures are like sudden electrical storms in the brain that can cause lasting damage. A set of immune cells in the brain called microglia may provide protection.

Microglia, immune cells disguised as brain cells, are known as the janitors of the brain. Dialing up their usual duties just enough could provide an avenue to treat neurodegenerative disease.

Inflammation is a complicated and important part of how the immune system responds to threats to the body. But when the inflammatory response goes awry, it can lead to serious problems.

While a strong immune response is essential to fight against viral infection, an immune system that continues to stay active long after the virus has been cleared can lead to lung damage.

Sepsis onset can be difficult to recognize, in part because its symptoms can mimic those of many other conditions. A treatment delay of even a few hours can make the difference between life and death.

DNA and mRNA vaccines produce a different kind of immune response than traditional vaccines, allowing researchers to tackle some previously unsolvable problems in medicine.

Though currently approved COVID-19 vaccines effectively provide immunity against the virus, it's unclear how long that protection will last.
