Following is a summary of current health news briefs. U.S. companies fear workplace coronavirus precautions do not address airborne risk

U.S. companies are raising new questions about how they can make workplaces safe after the world’s top public health agency acknowledged the risk that tiny airborne droplets of the novel coronavirus may contribute to its spread, industry healthcare consultants said. About two weeks ago, the World Health Organization called for more scientific study into airborne transmission of COVID-19. The move raised awareness of an issue excluded from U.S. government back-to-work guidelines, adding to the challenge of keeping people safe in offices, stores and work sites, these consultants said.

As pandemic flares, Chicago bans indoor bars and facials; Florida cases soar

The city of Chicago reimposed some coronavirus restrictions on Monday and the state of Florida reported more than 10,000 new cases for the sixth day in a row, as the pandemic raged across the United States. In a rare ray of hope, New York state reported the fewest hospitalizations from the coronavirus in four months and New York City entered a new phase of reopening on Monday. But the progress, in the very city and state that were once the epicenter, was eclipsed by the grim news nearly everywhere else. Wave of coronavirus study results raise hope for vaccines

Early data from trials of three potential coronavirus vaccines released on Monday, including a closely-watched candidate from Oxford University, increased confidence that a vaccine can train the immune system to recognize and fight COVID-19 without serious side effects. Whether any of these efforts will result in a safe and effective vaccine capable of protecting billions of people and ending the global pandemic is still far from clear. All will require much larger studies to prove they can prevent infection with the virus. Pfizer-BioNTech potential coronavirus vaccine shows promise in second early trial

German biotech BioNTech and U.S. drugmaker Pfizer Inc on Monday said data from an early-stage trial of their experimental coronavirus vaccine showed that it prompted an immune response and was well-tolerated, similar to results seen in prior early test. In the study conducted in Germany on 60 healthy volunteers, the vaccine induced virus-neutralizing antibodies in those given two doses, in-line with previous results from an early-stage U.S. trial. Israel in talks with AstraZeneca for potential COVID-19 vaccine, YNET reports

A Health Ministry spokesman said the ministry “does not disclose contacts being held in this sensitive matter.” Over a million doses of Oxford/AstraZeneca COVID-19 vaccine possible by September – researcher

Early estimates of the production a million doses of the University of Oxford’s experimental COVID-19 vaccine by September could be an underestimate depending on how quickly late-stage trials can be completed, a researcher said on Monday. “There might be a million doses manufactured by September: that now seems like a remarkable underestimate, given the scale of what’s going on,” Adrian Hill of University of Oxford said, referring to the manufacturing capability of partner AstraZeneca. Florida reports over 10,000 new cases of COVID-19 for sixth day in a row
