Evidence thus far shows that pregnant people infected with SARS-CoV-2 are at higher risk for severe disease and death, as well as complications in their pregnancies.

Regulatory T cells in the colon travel to muscles to promote wound healing in mice, raising questions about how antibiotics may impact injury recovery.

Experts have a decent grasp on how COVID-19 impacts cardiovascular health in the near term. The implications of long COVID, however, remain mysterious.

A clinical trial finds that the anticoagulant apixaban, which has been prescribed to help COVID-19 patients recover, is ineffective and in rare instances dangerous.

Scientists have genetically modified isolated microbes for decades. Now, using CRISPR, they intend to target entire microbiomes.

In humans, higher oxygen levels during ventilation are tied to an altered bacterial composition in the lungs, and mouse experiments show a causative link.

Work in rodents shows that the bacteria living in a mother’s gut can produce immunomodulatory metabolites and influence the production of maternal antibodies—both of which can affect her offspring’s development.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

Multiple candidates are in Phase 3 clinical trials for older adults and pregnant women, with some getting close to approval in the United States.
