Two drugs widely used to treat certain autoimmune diseases substantially improved clinical status and reduced deaths.

Protecting the immunocompromised is not only a matter of health equity, it’s critical to ending the pandemic.

Researchers showed that B cells evolve after COVID-19 vaccination to help improve protection against SARS-CoV-2 over time.

People with immune deficiency may not respond as well to vaccines but could still gain some protection.

Many with hep C or another liver disease have questions about what the side effects of COVID vaccines might be.

Long-lived memory immune cells continue to provide protection even after antibody levels drop.

The population of hepatitis C within the body is interconnected rather like an online social network and cooperates to evade the immune system...
