New story in Health from Time: COVID-19 Vaccine Shipped, and Drug Trials Start



Moderna Therapeutics, a biotech company based in Cambridge, Mass., has shipped the first batches of its COVID-19 vaccine. The vaccine was created just 42 days after the genetic sequence of the COVID_19 virus, called SARS-CoV-2, was released by Chinese researchers in mid-January. The first vials were sent to the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH) in Bethesda, MD, which will ready the vaccine for human testing as early as April.

NIH scientists also began testing an antiviral drug called remdesivir that had been developed for Ebola, on a patient infected with SARS-CoV-2. The trial is the first to test a drug for treating COVID-19, and will be led by a team at the University of Nebraska Medical Center. The first patient to volunteer for the ground-breaking study is a passenger who was brought back to the US after testing positive for the disease aboard the Diamond Princess. Others diagnosed with COVID-19 who have been hospitalized will also be part of the study.

Remdesivir showed encouraging results among animals infected with two related coronaviruses, one responsible for severe acute respiratory syndrome (SARS) and another for causing Middle East respiratory syndrome (MERS). Volunteers will be randomly assigned to receive either the drug or a placebo intravenously for 10 days, and they will have blood tests and nose and throat swabs taken every two days to track the amount of virus in their bodies. Even if the drug shows some efficacy in keeping blood levels of SARS-CoV-2 from growing, it could help to contain spread of the infection.

Moderna’s vaccine against COVID-19 was developed in record time because it’s based on a relatively new genetic method that does not require growing huge amounts of virus. Instead, the vaccine is packed with mRNA, the genetic material that comes from DNA and makes proteins. Moderna loads its vaccine with mRNA that codes for the right coronavirus proteins which then get injected into the body. Immune cells in the lymph nodes can process that mRNA and start making the protein in just the right way for other immune cells to recognize and mark them for destruction.

As Dr. Stephen Hoge, president of Moderna, told TIME earlier this month, “mRNA is really like a software molecule in biology. So our vaccine is like the software program to the body, which then goes and makes the [viral] proteins that can generate an immune response.” That means that this vaccine method can be scaled up quickly, saving critical time when a new disease like COVID-19 emerges and starts infecting tens of thousands of people.

New story in Health from Time: Here’s How Quickly Coronavirus Is Spreading in Your State

The novel coronavirus pandemic is a global crisis, a national emergency and a local nightmare. But while a great deal of the focus in the U.S. has been on the federal government’s response, widely criticized as slow and halting , the picture on the ground remains very different in different parts of the country. A TIME analysis of the per capita spread of the epidemic in all 50 states and Washington, D.C. found considerable range in the rate of contagion, and, in some parts of the country, a significant disparity compared to the national figure. The U.S., unlike nations such as South Korea and now Italy , has yet to show signs of bringing the runaway spread of the virus under control. However, while no single state is yet showing strong signs of bending the curve , some are faring much worse than others. The following graphic plots the rise in the total confirmed cases of COVID-19 per 100,000 residents in each state, plotted by the day that each state reported its first case....

New story in Health from Time: After Cruise Ships and Nursing Homes, Will Universities Be the Next COVID-19 Tinderboxes?

The fall semester has yet to begin, but student athletes training for the season can already be found on college campuses across the U.S. And so can COVID-19. Since the start of July there have been at least two outbreaks among student athletes, coaches, and staff—with 37 infected at the University of North Carolina (UNC) Chapel Hill and 22 at Boise State . Clusters of infection have been traced to college town bars popular with students. A common misconception is that young people with COVID-19 don’t die and therefore college re-openings pose little risk. Sadly, this isn’t the case. COVID-19 deaths in the young are rare, but they happen. Universities across the U.S. are mourning the loss of students in the lead-up to the school year, including Joshua Bush , a 30-year old nursing student at the University of South Carolina, Trevor Syphus Lee , a 27-year old senior at Utah Valley University, and Juan Garcia , a 21-year old Penn State undergraduate. One might imagine th...
