An experimental drug being developed by RedHill Biopharma Ltd. that improved outcomes in a randomized trial involving severely ill COVID-19 patients infected with earlier versions of the coronavirus is showing promise against the Omicron variant in test tube experiments, researchers said. Additionally, people living with well-controlled HIV infections are likely to have immune responses to the mRNA COVID-19 vaccines from Moderna and from Pfizer/BioNTech similar to those of otherwise healthy individuals, according to new data.

Although people who recover from COVID-19 usually gain some immune defenses against reinfection, they get additional protection from vaccines, especially against severe disease, according to two studies published on March 31 in The Lancet Infectious Diseases. Additionally, two gold-standard trials published in The New England Journal of Medicine on March 30 help settle questions about two controversial therapies touted by many early in the pandemic with decidedly mixed results – failure for the antiparasite drug ivermectin and success for antibody-rich blood plasma from COVID-19 survivors.

The Biden administration on Wednesday launched a new website to provide a clearinghouse of information on COVID-19 as part of a continuing effort to prepare Americans to live with the coronavirus.

The U.S. Food and Drug Administration will weigh the benefits of authorizing a round of boosters of either the Pfizer/BioNTech or Moderna COVID-19 vaccine to a broader population in the fall, a top official said on March 29.
