The interplay of vaccines and the emergence of variants is a complex question that we are monitoring. We will note that the emergence of variants of concern began before vaccine rollout programs occurred with the first notable one being in August 2020 with D614G. Therefore, as we continue to move forward, we must be ready and continue to invest in our ability to rapidly detect and understand the variants of concern, which is why we are investing $53 million in the integrated variants of concern strategy.
