Phase 3 clinical trial of investigational vaccine for COVID-19 begins – NIH

Multi-site trial to test candidate developed by Moderna and NIH. A Phase 3 clinical trial designed to evaluate if an investigational vaccine can prevent symptomatic coronavirus disease 2019 (COVID-19) in adults has begun. The vaccine, known as mRNA-1273, was co-developed by the Cambridge, Massachusetts-based biotechnology company Moderna, Inc., and the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Confusion spreads over system to determine priority access to Covid-19 vaccines – STAT News

On Tuesday, the National Academy of Medicine, tasked by top U.S. health officials, named an expert panel to develop a framework to determine who should be vaccinated first, when available doses are expected to be scarce.

How Much Can We Reduce COVID–19 Spread by Staying Home? A Lot, New Research Shows – Science Direct

In the case of infectious diseases such as coronavirus, R determines how many people will be infected by each person who already has the virus. To successfully defeat a pathogen like SARS-CoV–2, you need R to be less than 1 – meaning each person passes the infection on to less than one other person, which ultimately leads to fewer and fewer people being infected. In contrast, an R value greater than 1 represents a growing spread.

Association of cardiac infection with SARS-CoV-2 in confirmed COVID-19 autopsy cases – JAMA

Cardiac tissue from 39 consecutive autopsy cases were included. The median (interquartile range) age of patients was 85 (78-89) years, and 23 (59.0%) were women. SARS-CoV-2 could be documented in 24 of 39 patients (61.5%). Viral load above 1000 copies per μg RNA could be documented in 16 of 39 patients (41.0%). A cytokine response panel consisting of 6 proinflammatory genes was increased in those 16 patients compared with 15 patients without any SARS-CoV-2 in the heart. Comparison of 15 patients without cardiac infection with 16 patients with more than 1000 copies revealed no inflammatory cell infiltrates or differences in leukocyte numbers per high power field.

Why is the Tulane Outbreak Daily so late today?

If you have noticed the late delivery, and a day or two in last few weeks with no daily email, I’ve had some dentistry drama in the time of COVID. Cracked a tooth back in the days of shut down, and by the time the dentist opened again… there were issues. I have a few more appointments in the coming weeks, there may be another day or two of late or missing Tulane Outbreak Daily emails, but not to worry. I’ll catch up on the the latest interesting reads in the next edition.
