  1. Patients who have cardiovascular disease are at increased risk of serious complications from the flu, according to a new study. The study found that not only are traditional flu-related outcomes worse among some patients with CVD, but infection in those patients also is associated with an increased risk of cardiovascular events. Getting the influenza vaccine, however, substantially reduces cardiovascular risks.
  2. In the fight against multidrug-resistant bacteria, scientists have developed a new kind of antibiotic-free protection for wounds that kills drug-resistant bacteria and induces the body's own immune responses to fight infections.
  3. By creating the Universal Influenza-like Transmission (UnIT) score, which leverages data about past flu seasons, researchers have produced a new model of COVID-19 incidence that outperforms all other prediction models on average over the pandemic timeline so far.
  4. Researchers have described a novel host strategy for combating viruses such as measles virus that affect the mitochondria, structures within the cell. The presence of the RNA genome of the measles virus activates one pathway of innate immunity, and the release of mitochondrial DNA into the cell through the action of the virus also triggers a separate pathway dependent on a molecule known as cGAS.
  5. A cell-based influenza vaccine has effectively provided protection against the flu in children and adolescents, according to a new study.
  6. Medical researchers have shown that optimizing the energy metabolism of key cells enables people with HIV-1 to better defend themselves against the virus.
  7. For nearly a decade, scientists have known that HIV integrates itself into genes in cells that have the potential to cause cancer. And when this happens in animals with other retroviruses, those animals often develop cancer. But, perplexingly and fortunately, that isn't regularly happening in people living with HIV. A new study reveals why doctors aren't seeing high rates of T cell lymphomas -- or cancers of the immune system -- in patients with HIV.
  8. Poor timing of influenza vaccination campaigns in the semi-arid region of Brazil led to an increase in premature births, lower birth-weight babies and the need to deliver more babies by cesarean section.
