After the Delta mutant from the Corona virus occupied the whole world during the last period, the “Lampda” mutant entered the line again after it was found in at least 29 countries.
The World Health Organization has confirmed that infection rates in a number of countries are mainly linked to the lambda mutate, according to what the Science Alert website reported.
Peru recorded 596 deaths per 100,000 residents with this mutation, which is nearly double the country next most affected by the lambda mutation, Hungary, which recorded 307 deaths per 100,000 people.
The scientists explained that lambda has seven mutations in the spiky protein, which are mushroom-shaped protrusions on the outer envelope of the virus that help it attach to and invade our cells.
They added that these mutations on the mutant may facilitate attachment to our cells and make it difficult for our antibodies to attach to the virus and neutralize it.
A preliminary version of a study from New York University’s Grossman School of Medicine looked at the effect of the Pfizer and Moderna vaccines against the lambda variant.
The study found a 23-fold reduction in antibodies from the vaccine compared to the original virus
In parallel, researchers from the University of Chile investigated the effect of the Sinovac vaccine (also known as “CoronaVac”) against the variant and also found a 3-fold decrease in neutralizing antibodies compared to the original variant.
The Science Alert report indicated that these two studies found that neutralization was at least partially retained, indicating that this is promising due to the immune response resulting from vaccination.
According to the latest risk assessment conducted by Public Health England, on July 8, there is no evidence of a country that has outperformed Delta in the lambda mutant.
It is noteworthy that the new mutant was first discovered in Peru in January 2020, and in April 2021, more than 80% of the new cases of corona in Peru became from it.
