Chile: Delta variant doubles to 60% in just two weeks, outcompetes Gamma, Lambda, MU
The Delta variant, which was first detected in Chile just two months ago, is now found in 61% of all genome samples.… ...More...
Preprint: MU B.1.621 the most resistant variant to convalescent and vaccinated sera to date
Here, we demonstrate that the Mu variant is highly resistant to sera from COVID-19 convalescents and BNT162b2-vaccinated individuals. Direct comparison of different SARS-CoV-2 spike proteins revealed that Mu spike is more resistant to serum-mediated neutralization than all other currently recognized variants of interest (VOI) and concern (VOC).… ...More...
The stunning rise of the Mu variant
The new Mu variant, B.1.621, detected for the first time in Colombia, surpasses Lambda and Delta and is already ranked as the second with the highest circulation in Chile. … ...More...
Sinovac vaccine produces ten times fewer antibodies than Pfizer
A study conducted in Hong Kong on more than a thousand patients shows that the Coronavac vaccine, developed by the Chinese laboratory Sinovac, causes the production of ten times less antibodies than the vaccine developed by BioNTech and produced by Pfizer.… ...More...
Preprint: C.37 Lambda variant exhibits higher infectivity and immune resistance
“In this study, we demonstrated that three mutations, the RSYLTPGD246-253N, L452Q and F490S mutations, respectively confer resistance to the vaccine-induced antiviral immunity.… ...More...
Preprint: Infectivity and immune escape of the new coronavirus variant of interest C.37 Lambda
“We also observed that the spike protein of the Lambda variant presented increased infectivity when compared with the spike protein of the Alpha and Gamma variants, both of them with reported increased infectivity and transmissibility.… ...More...
Preprint: The emergence of Sars-CoV-2 coronavirus variant Lambda C.37 in South America
We report the emergence of a novel lineage of SARS-CoV-2 in South America, termed C.37. It presents seven nonsynonymous mutations in the Spike gene (Δ247-253, G75V, T76I, L452Q, F490S, T859N) and a deletion in the ORF1a gene (Δ3675-3677) also found in variants of concern (VOCs) Alpha, Beta, and Gamma.… ...More...
Peru: C.37 #coronavirus variant named Lambda by WHO
The World Health Organization (WHO) said Wednesday that the coronavirus variant of COVID-19, commonly known as C.37, has been named Lambda.… ...More...
Chile: Santiago goes back into lockdown despite 60% #coronavirus vaccination rate
As of the early hours of this Saturday, 12th June 2021, Santiago de Chile has once again entered quarantine.… ...More...
Sweden: so much for Herd Immunity and Light Touch pandemic policies
“Instead of following evolving evidence, the [Swedish] FHM has doubled down and defended its approach without reconsidering the assumptions on which the failed national approach is based.… ...More...
China: Our vaccines “don’t have very high protection rates,” says the director of Chinese CCDC
China’s top disease control official says the effectiveness of Chinese vaccines is low and the government is considering mixing them to give them a boost. … ...More...
Sinovac #coronavirus vaccine – 27.7% effective within the first two weeks, 56.5% effective two weeks after the second dose
The study by the University of Chile found inoculation to be 56.5 percent effective in protecting recipients two weeks after the second dose, and 27.7 percent effective within the first two weeks.… ...More...
Chile heads back into #coronavirus lockdown despite massive vaccination campaign with Sinovac vaccine
Chile’s big coronavirus vaccine bet on China’s Sinovac shots. Chile hopes to reach herd immunity by the middle of the year and is nearly halfway to vaccinating its entire population.… ...More...
