Coordinators of a global coronavirus vaccines funding scheme are looking at a wide range of potential prices for COVID-19 shots, with a reported $40 per dose price tag the “highest number” in that range, one of the co-leads of the project said on Monday. Seth Berkley, chief executive of the GAVI vaccine alliance, which is co-leading the COVAX facility designed to ensure fair global access to COVID-19 shots, said the facility had no specific target price and would also seek to negotiate tiered pricing for richer and poorer countries.

The U.S. has more COVID-19 testing than most. So why is it falling so short?

The United States might have more COVID-19 testing capacity than any other country. So why have we seen laboratories overwhelmed and many patients again waiting a week or more for results? At the heart of the crisis is a reliance by public and private labs on automated testing equipment that locks them in to using proprietary chemical kits and other tools made by a handful of manufacturers. In California breadbasket, hospitals overwhelmed as COVID-19 infections soar

Nearly 200 federal healthcare workers have been deployed to California’s Central Valley agricultural breadbasket, where hospitals are overwhelmed with COVID-19 cases as new infection rates soar, Governor Gavin Newsom said on Monday. The arrival over the past several days of Department of Defense personnel will help hospitals in the stricken region, where some hospitals and intensive care units are two-thirds full of COVID-19 patients. That has left little room for people who are ill from other conditions and is putting immense pressure on doctors, nurses and other healthcare workers trained in providing care to the sickest patients.

Moderna Inc’s vaccine against COVID-19 could be ready for widespread use by the end of this year, U.S. and company officials said on Monday, after the drugmaker announced the start of a 30,000-subject trial to demonstrate it is safe and effective, the final hurdle prior to regulatory approval. The trial is the first such late-stage study under the Trump administration’s program to speed development of measures against the novel coronavirus, adding to hope that an effective vaccine will help end the pandemic.

Miami medical teams feel helpless as COVID-19 devastates South Florida

As the coronavirus ravages Florida, healthcare workers in Miami hospitals are struggling to cope with the emotional and physical impact of treating a crushing wave of COVID-19 patients. After seeing 10,000 new cases a day become the norm across the state in July, many of those on the frontlines are frustrated with the apparent inability of local, state, and federal governments to coordinate an adequate response. They are equally aghast with what appears to be the reluctance or refusal of many Floridians to honor safety precautions to stop the spread of coronavirus.
