A new study reveals how the SARS-CoV-2 virus evolved from initially prioritizing increased transmissibility to enhanced immune evasion after the Omicron variant emerged according to Weill Cornell Medicine-Qatar (WCM-Q) researchers.

A recent Pfizer or Moderna mRNA-vaccine booster provided good but temporary protection against infection by the SARS-CoV-2 omicron variant.

Booster doses of mRNA vaccines provided strong protection against hospitalization and death from COVID-19 in Qatar, though breakthrough SARS-CoV-2 infections were greater for the omicron variant compared with the delta variant, according to a study by investigators at Weill Cornell Medicine—Qatar.

HIV epidemics are emerging and growing among female sex workers and their male clients in multiple countries in the Middle East and North Africa, and few of these epidemics have already reached their peak.

Researchers at WCM–Qatar hope to help Qatar curb its looming diabetes crisis.
