Engineering by Nature
Luft told Healthline that the key to creating the vaccine was to bioengineer a protein not found in nature. Using the scaffolding of a protein known as OspA, which is found on Borrelia's outer surface when it lives in ticks, the scientists created a new fusion protein called a chimera.
The chimera contains proteins from a wide range of Borrelia bacteria, making the vaccine effective against many different strains.
