In a recent study posted in the Research Square* preprint server, which is under consideration at a Nature Portfolio Journal, researchers evaluated the pathogenicity and replication potential of ...

Danish scientists found the BA.2 subvariant, which has rapidly become dominant in Denmark, spread more easily across all groups regardless of sex, age, household size and vaccination status. However, ...

In a recent study published in the Lancet, researchers evaluated the antibody neutralization sensitivity of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.2.75 subvariant.

Panel A shows the mutations of the omicron BA.1 and BA.2 sublineages in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein. Panel B shows neutralizing antibody titers that ...

Shown are neutralizing-antibody titers against virus pseudotyped with spike protein from ancestral severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) bearing the D614G mutation, along with ...

The omicron subvariants BA.1 and BA.2 of SARS-CoV-2 have dominated the COVID-19 pandemic in early 2022. In many countries, these viruses are now outcompeted by emerging subvariants, with BA.5 being ...

A recent study has revealed that Omicron sub variants are less severe than original Omicron variant and other original COVID variants(AP) Signalling a diminishing severity of SARS Cov-2, a US-based ...

Early studies suggest that the BA.2 lineage might prolong the Omicron wave, but won’t necessarily cause a fresh surge of COVID infections. COVID-19 researchers are rushing to understand why a relative ...

(CNN) — Scientists around the world are fast-tracking lab experiments to try to understand the highly mutated BA.2.86 variant of the virus that causes COVID-19. Results just beginning to emerge are ...

Of 1,02,315 confirmed COVID-19 cases in the US from March 3, 2020 to June 20 this year, there were 20,770 labelled as Delta variants, 52,605 labelled as Omicron B.1.1.529 variants, the original ...
