efficiently.
4- Lambda: This is a Columbian variant first detected in June 2021. It is thought by scientists
that Lambda may be resistant against vaccines. It's increased transmissibility showcases greater
infectivity than any other variant. The mutations inside make it more infectious. Now it has
spread in to 30 other countries including U.K.
