It was important to have a vaccine technology that allows them to both provide boosting doses if needed and to address potential changes in the virus itself if a new variant emerges that the vaccine does not protect against. While they have not seen any evidence that the circulating variants result in a loss of protection provided by their vaccine in their laboratory studies, they are taking multiple steps to be ready in case a strain becomes resistant to the vaccine.
