NIAID-supported research sheds light on why healthy people of the same age respond differently to vaccines.

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

Based on surveys conducted in 2015 and 2018, the number appears to have nearly tripled in San Francisco.

More than 95% of people who recovered from COVID-19 had durable immune system memory up to eight months after infection.

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

Plasma from recovered patients recently received a controversial FDA emergency use authorization as a potential treatment for COVID-19.

Tests like the one approved this week can show who is likely to be immune, but it’s not yet clear how long such immunity lasts.

The difference between hepatitis C virus and its antibodies can be confusing to understand, but important to know.

Ask Hep looks at the significance of hepatitis C antibodies.

Approximately 15 to 25 percent of people who contract hepatitis C will clear the virus spontaneously. Does this affect treatment decisions?

A positive hepatitis C test does not necessarily prove that someone has hep C. What other tests are needed?

If your hepatitis was cured, but a new doctor tells you that you have hep C, should you panic? A look at what may be going on.

There are three parts to testing for hepatitis C virus (HCV).

Researchers claim a recent trial of 180 patients proved the vaccine is safe, effective and faster than other current therapies.
