Reduced neutralization of SARS-CoV-2 B.1.617 by vaccine and convalescent serum
C Liu et al, Cell, June 16, 2021

We study the ability of monoclonal antibodies, convalescent and vaccine sera to neutralize B.1.617.1 and B.1.617.2 and complement this with structural analyses of Fab/RBD complexes and map the antigenic space of current variants. Neutralization of both viruses is reduced when compared with ancestral Wuhan related strains but there is no evidence of widespread antibody escape as seen with B.1.351. However, B.1.351 and P.1 sera showed markedly more reduction in neutralization of B.1.617.2 suggesting that individuals previously infected by these variants may be more susceptible to reinfection by B.1.617.2.

What is CDC doing to track SARS-COV-2 variants?
CDC, June 17, 2021

In the United States, CDC tracks emerging variants through genomic surveillance with the following approaches: Leading the National SARS-CoV-2 Strain Surveillance (NS3) system; Partnering with commercial diagnostic laboratories; Collaborating with universities; Supporting state, territorial, local and tribal health departments; Leading the SARS-CoV-2 Sequencing for Public Health Emergency Response, Epidemiology, and Surveillance (SPHERES) consortium.

Digital health: balancing innovation and cybersecurity
Lancet Respiratory Medicine editorial, June 16, 2021

Digital health is an area of medicine that has seen huge acceleration and investment globally over the past decade—even more so during the COVID-19 pandemic, when reliance on digital and telehealth has been essential. With this growth in digital health, however, comes concern surrounding the use of digital patient data and the associated risks of cybersecurity breaches.

Neutralization of SARS-CoV-2 Variants B.1.429 and B.1.351
X Shen et al, NEJM, June 17, 2021

The modestly lower value in neutralization titers against the B.1.429 variant seen in this study is similar to that we saw previously when neutralization of the B.1.1.7 variant was tested with the same assay using serum samples obtained from recipients of the mRNA-1273 and NVX-CoV2373 vaccines.4 These results, and the high efficacy shown by these vaccines, suggest that vaccine-elicited neutralizing antibodies are likely to remain effective against the B.1.429 variant. The magnitude of resistance seen with the B.1.351 variant is of greater concern with respect to current vaccines.

About COVID-19 GPH

COVID-19 GPH is an online, continuously updated, searchable database of published scientific literature, CDC and NIH resources, and other materials that captures emerging discoveries and applications of genomics, molecular and other precision medicine and precision public health tools in the investigation and control of COVID-19. Contents include PubMed records via an automated pubmed search algorithm, preprint records from NIH iCite, the relevant information from many media sources picked by experts, and linkages to contents from our curated PHGKB databases.

Genomics Precision Health (GPH): The use of pathogen and human genomics and advanced molecular detection methods in discovery, clinical and public health investigations and response to COVID-19.
Non Genomics Precision Health (non-GPH): The use of big data, data science, digital health, machine learning and predictive analytic methods (not involving genomics) in discovery, clinical and public health investigations and response to COVID-19

Following categories are annotated by LitCovid from NCBI NIH.
MechanismUnderlying cause(s) of covid-19 infections and transmission & possible drug mechanism of action
Transmission Characteristics and modes of covid-19 transmissions, such as human-to-human
