The correct response is: It has a viral genome that mutates very quickly.
This high mutation rate allows the viruses that cause the common cold (primarily rhinoviruses) to rapidly change their surface proteins, making it difficult for a vaccine to be effective over time as the immune system may not recognize the mutated strains.
