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 ...

In a recent study posted to the medRxiv* preprint server, researchers assessed the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) transmission dynamics and ...

Panel A shows mutations in the SARS-CoV-2 spike protein in omicron subvariants BA.1, BA.2, BA.2.12.1, BA.4–BA.5, and BA.4.6. BA.4 and BA.5 are grouped together because they have identical spike ...

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused the emergence of the coronavirus pandemic (COVID-19) that has caused over five million deaths and caused hundreds of millions of ...

In the absence of effective treatments for COVID-19, many countries have approved the therapeutic use of blood plasma from recovering patients because it contains antibodies against the coronavirus.

When some viruses infect our bodies, “our immune system can create a type of ‘permanent immunity’, meaning that once you’ve been exposed to that virus, you’ve got protection from it and are typically ...
