SARS-CoV-2 B 1 617 mutations L452 and E484Q do not work together to evade antibodies

SARS-CoV-2 B.1.617 mutations L452 and E484Q do not work together to evade antibodies A short report recently published in the Journal of Infectious Diseases demonstrates how spike mutations L452R and E484Q found in the variant B.1.617.1 of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) each confer modestly diminished sensitivity to Pfizer-BioNTech (BNT162b2) mRNA vaccine-elicited antibodies – with combined mutations having a similar impact as either one of them alone. Full global control of the coronavirus disease (COVID-19) pandemic has yet to be achieved, despite the fact that highly effective vaccines against its causative agent, SARS-CoV-2, are now at our disposal. This is partly due to the emergence of new viral variants with antibody escape mutations.

Study highlights risk of new SARS-CoV-2 mutations emerging during chronic infection

Study highlights risk of new SARS-CoV-2 mutations emerging during chronic infection SARS-CoV-2 mutations similar to those in the B1.1.7 UK variant could arise in cases of chronic infection, where treatment over an extended period can provide the virus multiple opportunities to evolve, say scientists. Given that both vaccines and therapeutics are aimed at the spike protein, which we saw mutate in our patient, our study raises the worrying possibility that the virus could mutate to outwit our vaccines Ravi Gupta Writing in Nature, a team led by Cambridge researchers report how they were able to observe SARS-CoV-2 mutating in the case of an immunocompromised patient treated with convalescent plasma. In particular, they saw the emergence of a key mutation also seen in the new variant that led to the UK being forced once again into strict lockdown, though there is no suggestion that the variant originated from this patient.
