Coronavirus Briefing: What Happened Today


At 6:45 a.m. today, a volunteer in Savannah, Ga., got an injection that kicked off the first large-scale coronavirus vaccine trial in the United States. Results of the trial could be available by November, said Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases.


The study will enroll 30,000 healthy people at about 89 sites around the country this summer to determine the vaccine’s safety and effectiveness. Half of the participants will receive two doses of the vaccine, 28 days apart, while the other half will get a placebo.

Researchers will then track the subjects for side effects and to see if fewer vaccinated people contract Covid-19. Because vaccines don’t always block an infection outright, researchers will also be monitoring whether the vaccine — developed by the biotech company Moderna and the National Institutes of Health — prevents severe illness or death.

Late Monday afternoon, the drug company Pfizer announced that it will also begin a late-stage study of a coronavirus vaccine, with the first shots to be given on Tuesday. The trial will also include 30,000 people, from 39 states in the United States, and from Brazil, Argentina and Germany.

Early tests of the Moderna vaccine showed that it stimulated a strong immune response against Covid-19, with minor and temporary side effects like sore arms, fatigue, aches and fever. If the vaccine is proven to be safe and effective, Moderna said it should be able to deliver 500 million doses this year, and up to a billion per year starting in 2021.

Face coverings have been touted as one of best ways to prevent those around you from contracting the coronavirus. Now, there is mounting evidence that masks also protect the people wearing them.

Different kinds of masks “block virus to a different degree, but they all block the virus from getting in,” said Dr. Monica Gandhi, an infectious disease physician at the University of California, San Francisco.

Dr. Gandhi and her colleagues make this argument in a paper that will be published in the Journal of General Internal Medicine. Drawing from animal experiments and observations of various events during the pandemic, they contend that people wearing face coverings will take in fewer coronavirus particles, which could make the disease less severe.

One animal study in China placed hamsters infected with the coronavirus alongside healthy ones, some of which were separated by a buffer of surgical masks. Many of the hamsters behind the masks didn’t get infected, while those that did showed milder symptoms.

But masks continue to be deeply divisive in the United States. In Illinois on Saturday, the “Million Unmasked March” drew about 150 demonstrators to the capital to protest state guidance requiring face coverings in schools this fall.

Masks as fashion: Japan is helping lead the way in innovative face coverings. Designers have made masks with pearls and high-tech fabrics, options for weddings and punk-inspired styles with leather and spikes. A start-up is even working on one that also serves as a walkie-talkie, personal secretary and translator.

I am having fun with my 11-year-old grandson, who is a budding artist, and a dozen friends. I email them an “art prompt” at the beginning of each week and they return artwork based on the prompt to me by Friday. I then create a PowerPoint gallery, which I return to them the next day.
