A nasal spray vaccine that puts your immune system on permanent high alert – and could one day protect against flu, COVID and future pandemics.

Your immune systems kicks into gear when you’re injured, both worsening and relieving pain.

The key players of our immune system aren’t well understood. Here’s how vaccines give our immune players a home advantage to fight infection.

Approaching heart failure like an autoimmune condition could offer new ways to improve patient survival.

The researchers found that mRNA-based COVID-19 vaccines could potentially help patients whose tumors don’t respond well to traditional immunotherapy.

Researchers are gaining insights into how external factors like air pollutants, diet and medications, and even microbes in the gut interact with regulatory T cells, for better or for worse.

Regulatory T cells help your immune system distinguish between ‘self’ and ‘nonself’ – and can open doors to better treatments for cancer, autoimmune disease and transplant rejection.

As it does with other pathogens, your immune system sees drugs as foreign invaders to be expelled from your body. But exploiting this process could reduce the side effects of chemotherapy.

Some studies indicate children with pets may be less likely to have allergies. But the evidence can be tricky to interpret.
