Heterologous prime-boost immunization with AstraZeneca and Pfizer COVID-19 vaccines safe and well-tolerated, study finds

A team of scientists from Germany has recently evaluated the reactogenicity profile of heterologous ChAdOx1 nCoV-19/BNT162b2 prime-boost vaccination among healthcare workers. The findings reveal that a 12-week interval regimen of heterologous vaccination is well-tolerated among participants. The study is currently available on the medRxiv* preprint server.

Memory B cells with a functional anti-SARS-CoV-2 response persist despite loss of specific IgG

In Munich, Germany, scientists at Ludwig Maximilian University studied temporal adaptive immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to better understand protection against re-infection. They found functional properties of persisting memory B specific to SARS-CoV-2 may help in protect against the virus.

SARS-CoV-2 virus persistence in immunocompromised individuals

Positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tests are frequently obtained from individuals that have already recovered from the virus in the past. They have therefore undergone seroconversion and bear the expected antibodies.

Modeling SARS-CoV-2 spike/human ACE2 complex identifies high-affinity variants that cause greater transmissibility

The study, published in the Journal of Molecular Biology, shows promise in detecting potential new variants that can cause the faster spread of COVID-19. The recent mutations and variants detected have caused the rapid spread of the infection in many countries.

Masks and physical distancing could reduce SARS-CoV-2 spread to 1% among essential food plant workers, says study

The food supply is an essential service. Yet, workers in this industry are at high risk of acquiring infection with the novel coronavirus in their workplace unless proper mitigation measures are put in place. A new study, released as a preprint on the medRxiv* server, shows that the risk of infection may be reduced to less than 1% with proper precautions.

North America has 87% of all unique SARS-CoV-2 S protein variants in the NCBI database among six continents

Recently, a team of researchers from various countries analyzed the unique variants of S proteins across six continents, including Africa, Asia, Oceania, Europe, South America, and North America. They wanted to characterize the unique S protein variants embedded in SARS-CoV-2 genomes infecting millions of people globally.

How SARS-CoV-2 evolved from a bat-to a human-adapted virus

New research published on the preprint server bioRxiv* performed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genomic simulations to understand the evolutionary transition from a bat-adapted SARS-CoV-2 to a human-adapted virus.
