claim: neutralization of sars-cov-2 lineage b.1.1.7 pseudovirus by bnt162b2 vaccine-elicited mouse sera.
evidence_1: recently, a new sars-cov-2 lineage called b.1.1.7 has emerged in the united kingdom that was reported to spread more efficiently than other strains.", "while the pseudovirus system used is a surrogate for authentic sars-cov-2, previous studies have shown excellent concordance between pseudotype neutralization and sars-cov-2 neutralization assays.i the preserved neutralization of the pseudovirus bearing the u.k. strain spike by bnt162b2- immune sera makes it likely that covid-19 caused by the u.k. virus variant will also be prevented by immunization with bnt162b2.",
