The Lambda Variant: What We Know So Far


Despite the numerous preventive protocols, new COVID-19 variants are appearing left and right. One of the new strains considered as a variant of interest is the Lambda variant. The Lambda variant is initially known as C.37. This variant was first detected in Peru late last year.

The Lambda variant is the dominant variant in Peru and shares mutations common with the Alpha, Beta, and Gamma variants. According to the World Health Organization (WHO), this variant has now been detected in over 29 countries. There is still so much to learn about this new variant and its epidemiological impacts. Here are details about the Lambda variant according to medical authorities and studies.

Delta vs. Lambda

The Delta variant remains as the “fastest and fittest” variant of the SARS-CoV-2. It is still the most dominating variant in the world. As of today, there are no pieces of evidence wherein the Lambda variant has outcompeted the Delta variant, according to Public Health England.


Possibly Vaccine Resistant

Japanese researchers found that this particular variant is more resistant to vaccines than the original SARS-CoV-2. They found that 3 mutations in the Lambda variant’s spike protein help it resist neutralization vaccine-induced antibodies.

Highly Infectious and Transmittable

According to Professor Pablo Tsukayama of Peru’s Cayetano Heredia University, its transmission rate is higher than any other variant. Japanese researchers also found two additional mutations, specifically T76I and L452Q, which help make the Lambda variant highly infectious.


As we continue to face COVID-19 and its various mutations, active detection and isolation of positive cases in our country is more imperative than ever. To learn more about MEDTEK’s PCR and rapid testing devices, feel free to fill out the form below.
