Antivirals, some antibodies found to work well against BA.2 Omicron variant of COVID-19 virus

by Eric Hamilton, University of Wisconsin-Madison Credit: Pixabay/CC0 Public Domain The antiviral therapies remdesivir, molnupiravir, and the active ingredient in Pfizer’s Paxlovid pill (nirmatrelvir), remain effective in laboratory tests against the BA.2 variant of SARS-CoV-2, the virus that causes COVID-19. The BA.2 variant also remains susceptible to at least some of the monoclonal antibodies used...

Econometrics methods show omicron variant is three times more contagious than delta

by Delene Beeland, University of North Carolina at Chapel Hill Credit: Pixabay/CC0 Public Domain Remember alpha, the first COVID-19 variant? It first appeared in Great Britain in late 2020. Alpha put the world on alert that mutations can change everything we thought we knew—within mere weeks—about what to expect from COVID-19. Back then, Carolina economist...

Booster dose of mRNA COVID-19 vaccine required for immune protection against Omicron variant of SARS-CoV-2, says study

by Massachusetts General Hospital Credit: Pixabay/CC0 Public Domain An additional “booster” dose of Moderna or Pfizer mRNA-based vaccine is needed to provide immunity against the Omicron variant of SARS-CoV-2, the virus that causes COVID-19, according to a study by researchers at the Ragon Institute of MGH, MIT, and Harvard. The results of this study, reported...

Yes, but U.S. health officials say early data suggests they may be less sensitive at picking it up. Government recommendations for using at-home tests haven’t changed. People should continue to use...
