Omicron and Delta Variant of SARS-CoV-2: A Comparative Computational Study of Spike protein
S Kumar et al, BIORXIV December 3, 2021

We used computational studies to examine the Delta and Omicron variants in this work and found that the Omicron variant had a higher affinity for human ACE2 than the Delta variant due to a significant number of mutations in the SARS-CoV-2 receptor binding domain, indicating a higher potential for transmission. Based on docking studies, the Q493R, N501Y, S371L, S373P, S375F, Q498R, and T478K mutations contribute significantly to high binding affinity with human ACE2. In comparison to the Delta variant, both the entire spike protein and the RBD in Omicron include a high proportion of hydrophobic amino acids such as leucine and phenylalanine. These amino acids are located within the protein's core and are required for structural stability.

Severe breakthrough COVID-19 cases in the SARS-CoV-2 delta (B.1.617.2) variant era
SY Wang et al, Lancet Microbe, December 3, 2021

Despite compelling evidence that SARS-CoV-2 vaccines are highly effective in preventing COVID-19 infections, breakthrough cases have been emerging at an increasing rate. The shifting landscape of breakthrough COVID-19 cases is likely to involve multiple factors, including demonstrated waning of antibody response after full vaccination7, 8 and emergence of variant strains of SARS-CoV-2.

CDC Data Tracker COVID Weekly Review

As of December 2, 2021, more than 234 million people in the United States have received at least one dose of a COVID-19 vaccine. However, vaccination among pregnant people remains low. CDC’s COVID Data Tracker shows that as of November 27, 2021, the proportion of fully vaccinated pregnant people has increased to 35%, but most pregnant people remain unprotected against COVID-19.

Inside a Sequencing Lab on the Front Lines of America’s Search for Omicron
M Smith, NY Times, December 4, 2021

In the United States, a hunt for the variant began last week when South African researchers announced Omicron’s array of worrisome mutations. The search has intensified in recent days, with at least 12 states identifying cases. Researchers are combing through wastewater samples for any sign of the variant. Contact tracers are ramping up efforts in places where cases have emerged. And at sequencing labs like the one in Nebraska, a state where case rates are already high and hospitals are already strained, scientists have sped up the screening of samples from international travelers to see if Omicron has arrived.
