TL;DR: In this article, the authors analyzed the emergence of SARS-CoV-2 in Russia in March and April 2020 and found that the sampled viral diversity has originated from at least 67 closely timed introductions into Russia, mostly in late February to early March.

TL;DR: It is estimated that the sampled viral diversity has originated from 67 closely timed introductions into Russia, mostly in late February to early March, suggesting that border closure with China has helped delay establishment of SARS-CoV-2 in Russia.

TL;DR: It is suggested that CD8 T cell escape may be an underappreciated contributor to SARS-CoV-2 evolution in humans.

TL;DR: Growth curve experiments and ELISA data show that, at least in the first viral replication cycle, mutations G123A and A132G affecting RNA structure in the (82–148) NS RNA region influence NS1 protein expression.

TL;DR: The data obtained show that the level of anti-SARS-CoV-2 S-protein antibodies 42 days after Gam-COVID-Vac vaccination is significantly higher than after CoviVacvaccine, and an increase in thelevel of IgG in both groups indicates the ability of both vaccines to stimulate the production ofAnti-Sars- CoV antibodies.
