New variant:
“ A newly described SARS-CoV-2 lineage C.37 was recently designated as a variant of interest by the World Health Organization (WHO) on June 14th and denominated as the Lambda variant. Its presence was reported in more than 20 countries as of July 2021, and most sequences to date stem from South American countries – particularly for Chile, Argentina, Ecuador and Peru.
And albeit the Lambda variant is characterized by specific mutations in the SARS-CoV-2 spike glycoprotein, their exact impact of infectivity and potential escape to neutralizing antibodies are still unknown. The latter is particularly important in countries currently undergoing massive vaccination efforts.
Since one of such countries is Chile, a research group led by Dr. Mónica L. Acevedo from the University of Chile School Of Medicine aimed to appraise the impact of the Lambda variant on the neutralizing antibodies responses stemming from the inactivated virus vaccine CoronaVac (also known as the Sinovac COVID-19 vaccine).”
Oh, and it looks like those people who took Pfizer May need a booster shot, as the effectiveness is showing signs of wearing off.
