FDA approval of two over-the-counter rapid antigen tests promises to transform the testing landscape around COVID-19, lowering cost and giving the certainty of knowing when you’re infected to the individual, a Harvard epidemiologist said.

Researchers at Harvard Medical School and affiliated institutions have shown that a personalized cancer vaccine that is specific to an individual’s tumor has lasting effects, detecting vaccine-related immune system changes years after the vaccine was given.

New study provides insights on how stress-related brain activity can temporarily damage the heart.

Pregnant women show robust immune response to COVID vaccines, pass antibodies to newborns.

A $25 billion investment in global vaccines would bring a five-to-one economic return and save many lives, according to Rebecca Weintraub, an HMS global health expert.

Environmental factors such as diet make major impacts in the gut microbiome, a new study shows.

The risk of future cancers was lowest among participants in a community-based observational study who had a heart-healthy lifestyle.

With 500,000 deaths due to COVID, the U.S. has become a nation in mourning, often alone, also dealing with the trauma of the pandemic’s other effects, a combination that worries mental health experts.

Can the current crop of vaccines get us to herd immunity even if variants become widespread? A Harvard immunologist says yes.

A Harvard epidemiologist said the forces of seasonality, slowly rising immunity, and shifting personal behavior will likely create a viral variant landscape with regional spikes in the months to come rather than a uniform national wave.
