Offspring of animals subjected to a real or simulated pathogen were more able to fend off disease, a study finds.

Both of the mRNA vaccines available in the US are highly effective against severe COVID-19, but recent studies suggest that Moderna’s elicits a stronger immune response and might be better at preventing breakthrough infections.  

Researchers’ painstaking examinations have begun to reveal how the virus wreaks havoc in multiple organs and tissues.

Scientists are on the hunt for a shot that will protect against not only SARS-CoV-2, but other members of its family that may emerge in the future.

Researchers at Imperial College London and the University of Oxford are exposing healthy volunteers to SARS-CoV-2 for science.

A review of hundreds of cases finds that only a minority of patients noted being sick with a coronavirus infection prior to developing the severe inflammatory condition.

Rollouts of the shot have ground to a halt following reports of blood clots, but health authorities say that these fears are unfounded and vaccination programs should continue.

Instead, the full report will be available in mid-March.

Stronger interferon production, greater T cell activation, and increased susceptibility to autoimmunity are just some of the ways that females seem to differ from males.

Males and females show differences in gene expression, cell activation, and antibody production in response to some viral infections, but whether these influence COVID-19 outcomes is still unclear.

Death rates among blood cancer patients who contract COVID-19 are higher than for those with other cancers, pointing to impaired immunity that makes it hard to overcome the virus.

With many millions of people waiting several weeks to receive a second COVID-19 vaccine dose in some countries, experts consider the possibility that SARS-CoV-2 could evolve vaccine resistance.

Half a year after infection, people who had recovered from COVID-19 had robust antibodies, along with traces of the virus in their gut, which may drive long-lasting immunity.
