Experimental intranasal vaccine triggers broad immune response against multiple strains of H5N1

Researchers at the University of Maryland School of Medicine's Center for Vaccine Development and Global Health (CVD) reported encouraging results from an early phase clinical trial that found an experimental intranasal vaccine triggered a broad immune response against multiple strains of H5N1 "bird flu".

Common viruses sharply raise heart attack and stroke risk, major global review shows

In the largest synthesis to date, researchers reviewed 155 studies linking viral infections, including influenza, SARS-CoV-2, HIV, hepatitis C, and shingles, to increased risks of coronary heart disease, stroke, and heart failure. The findings highlight viral infection prevention and vaccination as underappreciated strategies for cardiovascular protection.

Understanding age-related changes in T cells and vaccine response

As flu season approaches and public health officials roll out their annual push for vaccination, Allen Institute scientists are learning why vaccines can trigger a weaker response in older adults, around age 65, and what can be done to improve them.

Some acute and chronic viral infections linked to increased risk of cardiovascular disease

In the weeks following a bout of influenza or COVID, the risk of heart attack or stroke may rise dramatically, and chronic infections such as HIV may increase the long-term risk of serious cardiovascular disease events, according to new, independent research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

New epimodulation approach improves outbreak forecasts

During an epidemic, some of the most critical questions for healthcare decision-makers are the hardest ones to answer: When will the epidemic peak, how many people will need treatment at once and how long will that peak level of demand for care last? Timely answers can help hospital administrators, community leaders and clinics decide how to deploy staff and other resources most effectively.
