Even partial protection of one dose could be enough to slow the spread of the virus, the UW Medicine researchers argue in a paper.

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.

SEATTLE - The race to develop and administer a COVID-19 vaccine continues. It comes as scientists are predicting an increase in COVID cases from the holidays.

The glimmer of hope, however, comes in the form of these vaccines. Pfizer and Moderna's versions are being rolled out to healthcare workers and people 65-years-old and older, but Maryland-based Novavax is currently conducting its Phase III trial on their COVID-19 vaccine.

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.

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.
