• Watch: How - and why - coronaviruses mutate

    12 days ago - By STAT

    Like all viruses, SARS-CoV-2, the virus that causes Covid-19, is mutating all the time. Recently some concerning mutations have emerged: the B.1.1.7 variant first discovered in the United Kingdom, which is thought to be approximately 50% more contagious, and the E484K variant first seen in South Africa , which may also have potential to decrease the efficacy of vaccines. These variants are not believed to lead to more serious disease, but a more transmissible virus can put even more stress on an already overloaded health care system, and ultimately lead to more deaths.

  • Opinion: Businesses across the supply chain must work together to make Covid-19 vaccines

    As a scientist leading a company focused on RNA, I have cheered Pfizer, BioNTech, Moderna, and others as the biopharmaceutical industry raced to create vaccines that will end the tragic loss of life and the economic devastation wrought by Covid-19.
    So far, two Covid-19 vaccines, one from Pfizer/BioNTech and one from Moderna, have been approved by the FDA under emergency use authorizations. Both are RNA-based vaccines that show strong efficacy and few side effects. Other vaccines, using other technologies, have been approved for use in other countries.

  • Covid-19 deaths are the highest they've ever been - and the more infectious variants could make things much worse

    12 days ago - By STAT

    As horrific as the U.S. Covid-19 outbreak looks right now, it is almost certainly about to get worse.
    They've raced through South Africa, the United Kingdom, and, increasingly, elsewhere, and now, new, more infectious variants of the coronavirus have also gained toeholds in the United States. If they take off here - which, with their transmission advantages, they will, unless Americans rapidly put a brake on their spread - it will detonate something of a bomb in the already deep, deep hole the country must dig out of to end the crisis.
