Some children who experience the severe inflammatory condition after COVID-19 may continue to experience milder problems such as muscle weakness or anxiety even after that period, according to a small observational study in the UK.

By avoiding the production of antibodies, something vaccines ordinarily induce, the immunization sidesteps the problem of antibody-dependent enhancement, which can amplify infection by a similar virus and is known to occur with dengue and Zika.

The FDA and CDC are investigating a handful of reports of blood clots that occurred several days after people received the one-and-done shot.

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.

Stanford University researchers determined the code from spare drops in discarded vials of the COVID-19 vaccine and published it on GitHub.

Altered gut microbiome composition in obese mice and human patients is linked with severity of disease after bone marrow transplantation, a study found.

In the armpit lymph nodes of people who had received the mRNA vaccine against SARS-CoV-2, researchers found germinal centers needed to generate long-lived antibody-making cells.

In a new study, human and mouse cells recognized only one in five bacterial species collected from more than a mile below the Pacific Ocean’s surface.

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.

Mix-and-match shots could simplify vaccine rollout and stimulate more-robust immune responses. Ongoing clinical trials will soon give answers.

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

The P.1 variant, which has also been detected in five US states, could be responsible for cases of reinfection, according to a preprint.

A treatment of two monoclonal antibodies against SARS-CoV-2 is ninefold less effective in the lab against the B.1.351 variant than against the dominant version of the virus.

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.

A preprint casts doubt on vaccine effectiveness in light of certain mutations in the 501Y.V2 variant that emerged from South Africa.

The majority of people experiencing anaphylaxis had a history of allergic reactions, a report by the agency finds.

The head of Operation Warp Speed says that by spreading out doses of the Moderna vaccine, more people would be able to get some level of protection sooner, a strategy opposed by other experts.

Around 100 people were infected at a scientific meeting hosted by Biogen in Boston in February. Then they went back home, taking the virus with them.

In a year of racial tumult, Black scientists are uniting for visibility and action. 

Government authorities say because the animals are good hosts of the novel coronavirus, and this new viral variant could undermine vaccine efforts against COVID-19, they are destroying the nation's entire stock of mink.
