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.

Certain drugs used to treat HIV may have a role in preventing SARS-CoV-2 infections, according to preliminary data that may help explain why people living with the condition have not appeared to be at higher risk for serious COVID-19 despite being generally more vulnerable to infections. Additionally, having COVID-19 and influenza at the same time puts hospitalized adults at much greater risk of critical illness and death compared to having COVID-19 without the flu, researchers reported in The Lancet.

Ozempic

The U.S. Food and Drug Administration approved a 2 mg dose of Novo Nordisk’s Ozempic (semaglutide) injection, a once-weekly glucagon-like peptide-1 (GLP-1) analog indicated along with diet and exercise to improve blood sugar in adults with type 2 diabetes and to reduce the risk of major cardiovascular events such as heart attack, stroke or death in adults with type 2 diabetes and known heart disease.
