The Good News of COVID-19 Is Sticking, For Now – The Atlantic
All major indicators of COVID-19 transmission in the United States continue to fall rapidly. Weekly new cases have fallen from 1.7 million at the national peak in early January to fewer than 600,000 this week, and cases have declined in every state. As we’ve seen at many points in the pandemic, case numbers are changing most quickly, with hospitalizations and deaths declining after a delay: Cases have been falling sharply for five weeks, hospitalizations for four, and deaths for two. In this week’s numbers from nursing homes and other long-term-care facilities, we are now seeing solid declines in deaths correlated with COVID-19 vaccinations in this most vulnerable population.

South Africa Study Shows Power of Genomic Surveillance Amid COVID-19 Pandemic – NIH Director’s Blog
Considerable research is underway around the world to monitor the spread of new variants of SARS-CoV-2, the coronavirus that causes COVID-19. That includes the variant B.1.351 (also known as 501Y.V2), which emerged in South Africa towards the end of 2020 [1, 2]. Public health officials in South Africa have been busy tracing the spread of this genomic variant and others across their country. And a new analysis of such data reveals that dozens of distinct coronavirus variants were already circulating in South Africa well before the appearance of B.1.351.

Delayed Second Dose versus Standard Regimen for Covid-19 Vaccination – NEJM
You chair the Governor’s task force on rollout of the Covid-19 vaccine. Given concerns about the limited availability of the two-dose mRNA vaccine, you have been asked to weigh in on the debate regarding the most effective use of the currently available doses. Should people who have already received a first dose of vaccine have their second dose delayed by a number of months until there is a greater supply, so that more people can receive a first dose? Or should those who have gotten the first dose receive the second dose according to the standard schedule, 3 to 4 weeks after the first dose, as recommended by the Food and Drug Administration (FDA)? You must consider the benefits and risks of the two approaches, on both individual and population levels, and decide what to recommend to the task force.
