University of Chile Scientists' Study Indicates Sinovac’s Vaccine Elicits More Transmissible & Potent Variant called Lambada

The variant of concern (VoC) called C.37 or the “Lambda variant,” was probably first identified in Peru about one year ago, which fuels growing concern that mutations could overpower existing COVID-19 vaccines. The World Health Organization (WHO) reports that this mutant variant could not only boost transmissibility but also strengthen the pathogen’s resistance to vaccine-elicited neutralizing antibodies. It is not known yet what the impact of this variant will be, reports a new study, but the investigators do speculate that there could be a result of this viral adaptation to the CoronaVac vaccine, produced by the Chinese corporation Sinovac. That’s right: if this study is correct, the CoronaVac vaccine could be correlated to a mutation, one that’s led to a more transmissible and potent mutant. The authors suggest mass vaccination programs conducted directly in SARS-CoV-2 hotspots should be coupled with "strict genomic surveillance."
