Giving one dose of the COVID-19 vaccines currently approved in the United States could curtail the spread of the SARS-CoV-19 in the community more quickly than the recommended two doses, say two vaccine experts at the University of Washington School of Medicine.

Volunteer enrollment begins for Phase III clinical trial that will determine the efficacy of Novavax vaccine candidate.

UW Medicine investigators are starting volunteer enrollment for an investigational COVID-19 vaccine clinical trial. The Phase III study will examine whether the Novavax vaccine candidate can protect against SARS-CoV-2, the coronavirus responsible for COVID-19.

How Safe and Effective Are the New Coronavirus Vaccines?

The U.S. Food and Drug Administration (FDA) has granted emergency use for two new coronavirus vaccines, one developed by the drug company Pfizer and the biotech company BioNTech and the other by the biotech company ModernaTX. Both are mRNA vaccines and have similar structure.

Both vaccines contain modified mRNA that provides the instructions for the synthesis of the SARS-CoV-2 spike glycoprotein antigen. Its mRNA is enveloped in lipid nanoparticles (LNPs) to prevent degradation and enhance uptake into cells.

Summary of Evidence Related to Indoor Ventilation to Reduce SARS-CoV-2 Transmission

This updated in-depth summary (previously released on December 21, 2020) is issued in response to new information that we received about updated definitions of aerosol particles that show that larger respiratory particles (<100 μm) can remain airborne for extended periods, and that in enclosed areas with poor ventilation, these aerosols containing infectious SARS-CoV-2 can spread beyond 6 feet and build up in a room. We apologize for not including this information in the earlier version of this summary.

Who Gets COVID-19 Vaccine Next? Older Adults and 'Frontline Essential Workers,' CDC Advisers Recommend (quotes Beth Bell)

By Jacqueline Howard and Jen Christensen, CNN

(CNN)Vaccine advisers to the US Centers for Disease Control and Prevention voted 13-1 on Sunday to recommend that both older adults, ages 75 and older, and "frontline essential workers" including first responders be next in line to receive Covid-19 vaccines.

That would put those people in "Phase 1b" of allocating the vaccine nationwide.

The Health Effects of Climate Change (includes Kris Ebi)

The December 2020 issue of Health Affairs is the first-ever focused exclusively on the intersection of climate and health. It covers topics including the health sector’s contribution to carbon emissions and other forms of pollution, how communities are affected by and adapting to the changing climate, and policies to protect against further damage. Kristie Ebi, UW CHanGE, served as theme adviser of the issue.
