The Director of the WHO Regional Office, Carissa Etienne, said: The evidence available so far about this mutation indicates its high risk. Especially in terms of its speed of transmission and its ability to resist immunity arising from vaccines and recover from the epidemic.
The UN official added: "We still do not have sufficient data to determine the extent of the seriousness of this mutation and its final specifications, but the scientific indicators gathered so far by experts do not give rise to optimism."
This mutation was first discovered in Peru in January 2020, and in April 2021, more than 80% of new cases of corona in Peru became from this mutation, according to "Sky News".
On June 14, 2021, the World Health Organization announced this mutation, calling it the "Lambda variant", and considered it an interesting one.
The mutant is spread in 29 countries, and at high levels in South American countries in particular. In recent months, the lambda variant has been detected in 81% of COVID-19 cases in Peru that have undergone genetic sequencing tests, and 31% of similar cases in Chile.
Among the very few studies conducted on the lambda mutation and its ability to resist the Chinese Coronavac vaccine, it was found that it has the ability to resist it up to 64% of cases, according to the Chilean virologist Ricardo Soto. A study conducted by experts from New York University showed that this mutation is resistant to the Pfizer and Moderna vaccines by up to 22% in some cases.
