Good question! The expression "to lend itself" means to be good or suitable for a cause or purpose. Here, the speaker is saying that the virus itself was helpful or suitable for the purpose of creating a vaccine designed to prevent virus infection. Ex: This textbook lends itself as an effective exam revision resource. Ex: His face lends itself to cinema. Ex: Her mind really lends itself to the creation of new innovative technologies.
