Short-term apnea is more common among hospitalized preterm infants who receive their 2-month vaccines compared with those who do not, according to the results of a randomized clinical trial published in JAMA Pediatrics.

The FDA is adding a warning about Guillain-Barré syndrome to the respiratory syncytial virus vaccines manufactured by GSK and Pfizer based on data that suggest there may be a link between the shots and the rare disorder.

An FDA advisory committee said it wants to see more data to understand the implications of what the FDA called an “imbalance” in cases of severe respiratory syncytial virus among infants participating in an early-stage RSV vaccine trial.

The simultaneous administration of adjuvant zoster and influenza vaccines posed no additional safety risks in older adults, results from a randomized study showed.

As older Americans continue to shoulder much of the COVID-19 burden, new data show that most went without a vaccine last winter and that those who got sick rarely received antivirals.

The University of Oxford announced recently that researchers initiated the first-in-human trial of a Marburg virus vaccine to test its safety and evaluate its immune response among a young, healthy population.

A first-in-human clinical trial will assess the safety of a personalized vaccine to treat diffuse hemispheric glioma, an aggressive brain tumor.

The FDA on Thursday announced that it has greenlit the updated COVID-19 vaccines manufactured by Moderna and Pfizer-BioNTech, which the companies said should be available within days.
