For the first time since the Salvagene SARS-CoV-2 Task Force was established 18 months ago, a difference of opinion has arisen, specifically with regard to the Lambda variant. What everyone agrees on is that the Lambda or C.37 variant is clearly more contagious than the original Wuhan strain. In addition, it is much more resistant to antibodies, and the existing vaccines therefore have a reduced efficacy against it. The reason for this is three mutations in the spike protein, which render it less susceptible to neutralization by antibodies. Added to which there are two mutations that make the variant itself more infectious.
