The National Institutes of Health (NIH) (@NIH), a part of the U.S. Department of Health and Human Services, is the nation’s medical research agency — making important discoveries that improve health and save lives.
About the NIH Director
Francis S. Collins, M.D., Ph.D. (@NIHDirector) was appointed the 16th Director of NIH by President Barack Obama and confirmed by the Senate. He was sworn in on August 17, 2009. In this role, Dr. Collins oversees the work of the largest supporter of biomedical research in the world, spanning the spectrum from basic to clinical research. Here are some excerpts from the his latest blog posts with links to read in entirety.
Mapping Which Coronavirus Variants Will Resist Antibody Treatments
You may have heard about the new variants of SARS-CoV-2—the coronavirus that causes COVID-19—that have appeared in other parts of the world and have now been detected in the United States. These variants, particularly one called B.1.351 that was first identified in South Africa, have raised growing concerns about the extent to which their mutations might help them evade current antibody treatments and highly effective vaccines.
While researchers take a closer look, it’s already possible in the laboratory to predict which mutations will help SARS-CoV-2 evade our therapies and vaccines, and even to prepare for the emergence of new mutations before they occur. In fact, an NIH-funded study, which originally appeared as a bioRxiv pre-print in November and was recently peer-reviewed and published in Science, has done exactly that. In the study, researchers mapped all possible mutations that would allow SARS-CoV-2 to resist treatment with three different monoclonal antibodies developed for treatment of COVID-19.
Can Blood Thinners Keep Moderately Ill COVID-19 Patients Out of the ICU?
One of many troubling complications of infection with SARS-CoV-2, the coronavirus that causes COVID-19, is its ability to trigger the formation of multiple blood clots, most often in older people but sometimes in younger ones, too. It raises the question of whether and when more aggressive blood thinning treatments might improve outcomes for people hospitalized for COVID-19.
The answer to this question is desperately needed to help guide clinical practice. So, I’m happy to report interim results of three large clinical trials spanning four continents and more than 300 hospitals that are beginning to provide critical evidence on this very question [1]. While it will take time to reach a solid consensus, the findings based on more than 1,000 moderately ill patients suggest that full doses of blood thinners are safe and can help to keep folks hospitalized with COVID-19 from becoming more severely ill and requiring some form of organ support.
Following COVID-19 Vaccines Across the United States
Recently, there is a new and very hopeful COVID-19 number for everyone to track: the total number of vaccine doses that have been administered in the United States. If 80 percent of Americans roll up their sleeves in the coming months and accept COVID-19 vaccinations, we can greatly slow the spread of the novel coronavirus in our communities and bring this horrible pandemic to an end in 2021.
So far, more than 20 million people in our country have received one or two doses of either the Pfizer or Moderna vaccine. While this number is lower than initially projected for a variety of logistical reasons, we’re already seeing improvements in the distribution system that has made it possible to get close to 1 million doses administered per day.
