The lambda variant, first detected in Peru in August 2020 and spreading through South America, made its way to the U.S. for the first time on July 22 in a Houston hospital.
There are 1,053 cases of the lambda variant in the U.S. since the first case was detected, according to GISAID, an initiative dedicated to promoting COVID-19 data through genomic sequencing.
Japanese researchers at the University of Tokyo posted a lambda variant study that shows it is highly infectious and more resistant to COVID-19 vaccines.
This study posted on July 28 on bioRxiv, a database for unpublished preprinted studies, has not been peer reviewed or published.
The study shows three mutations in the lambda variant's spike protein — RSYLTPGD246-253N, 260 L452Q and F490S — which allow for the variant to resist vaccine-induced neutralizing antibodies. Two other mutations — T76I and L452Q — are responsible for making lambda highly infectious.
