He also worked on immunizations against polio, rubella, influenza, and more.

Researchers find signatures pre- and post-vaccination that correlate with a more robust immune response. 

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. 

In clinical trials, the new inoculation demonstrated greater protection for children and people older than 45 than the existing dengue vaccine.

Researchers say they’re abandoning the project in its current form—one of several that aims to induce what’s known as mucosal immunity against SARS-CoV-2.

Recent studies have lent support for a variety of hypotheses explaining the debilitating symptoms affecting millions of people after SARS-CoV-2 infection.  

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.

Researchers report that vaccination against proteins found on profibrotic cells reduced liver and lung fibrosis in laboratory rodents.

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.

Analyses suggest the virus has been silently spreading in nearby counties since May.

The newly authorized intradermal vaccination only requires one-fifth of the usual vaccine dose. This will help stretch out the limited vaccine supply, experts say, but only if healthcare personnel receive sufficient training.

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.
