Pregnancy-induced changes in the immune system are key to a successful birth. Understanding those changes could allow researchers to protect both mother and child.

Aberrant immune activation, the main cause of prematurity and stillbirths, could be preventable through interventions such as maternal vaccination. 

When fused to RSV, influenza A virus is better able to escape antibodies that usually neutralize it, an in vitro study finds.

A vaccine strategy involving formulation changes, an initial escalating dose, and a longer wait for booster immunization results in more-effective antibody production against HIV in rhesus monkeys, a study finds.

BA.2.75 is spreading rampantly in India and has so far reached at least 20 other countries, but it doesn’t seem to be outcompeting other Omicron SARS-CoV-2 subvariants.

Studies show that a fourth mRNA vaccine dose offers the elderly and other high-risk groups strong protection against hospitalization and death from COVID-19, but experts say benefits for other populations may be more limited.

The Scientist asks Brigham and Women’s Hospital infectious disease specialist Lindsey Baden about testing for prior infections.

IgA antibodies appear to bind to specific species of commensal gut bacteria in mice, according to a study.

Researchers are turning to the immune system for help in treating addiction and preventing overdose.

Two recent papers provide insight into possible risk factors for developing the chronic condition, including autoantibodies and diabetes.

Unlike studies of antibody-rich transfusions in hospitalized patients, which overall have not found clear benefits, a new randomized trial finds that early convalescent plasma treatment cuts hospitalizations in half.

All antibodies against SARS-CoV-2 found in breast milk neutralized the virus.
