Two phase 1 clinical trials of a nasal spray containing influenza virus–specific monoclonal antibodies conclude that it’s safe—although it won’t replace flu vaccination because it stays in the nose for only a few hours, researchers say. The trial findings, published in Science Translational Medicine, form the basis for efficacy studies in people and suggest that the spray may fill a gap by quickly providing short-term protection in a flu pandemic, particularly for high-risk populations such as health care workers. (Van Beusekom, 2/18)

Scientists say they have identified a mutated autoantibody gene as the mechanism behind rare but serious abnormal blood clotting after adenovirus-based COVID-19 vaccination, a discovery that they say will allow vaccine developers to avert the disorder by adjusting the adenovirus protein in the vaccines while still preserving their efficacy.

Scientists showed in a new study published Thursday that they could use blood draws to build a “clock” for Alzheimer’s disease that could roughly predict when symptoms will develop, findings that could eventually transform how the illness is diagnosed and treated. A simple blood test can help diagnose Alzheimer’s, but the study in the journal Nature Medicine shows how these kinds of tests could one day play a greater role in preventing the insidious, memory-robbing illness. In the new study, researchers built a model that could use blood test results to forecast symptom onset within a margin of three to four years. (Johnson, 2/19)
