Chromatography in the Vaccine Pipeline

As vaccine technologies evolve, sophisticated analytical tools are needed to support vaccine discovery, development and manufacturing. In this article, we explore the role of chromatography in the vaccine pipeline.

Why Do Some Vaccines Create Long-Lived Responses? Ask the Researcher

In this Ask the Researcher, we spoke with Professor David Tarlinton to learn more about long-lived plasma cells; how they are made and how they are stored.

Long-Term Exposure to Air Pollution Undermines the Immune System

Inhaled pollutants can collect in the lymph nodes associated with the lung, accumulating over decades and weakening the immune cells' ability to fight off lung infections.

HIV Infection Leaves a "Memory" in Cells

New study reveals why comorbidities persist in people living with HIV, despite suppressing the virus through treatment.
