Remember, the HealthVault is not a PHR, but a container of sorts, a place where PHRs are securely stored, maintained, accessed, and shared.
Betty was single, but she did have a family member, Spike, her pet dog. So Betty added a PHR for Spike to her HealthVault.
When she clicked on Add a Person beneath her picture, she was able to create a new PHR for Spike. [Note that pet–just like spouse, daughter, and sister–is available as a choice for Relationship to You. So storing your pet’s PHR in HealthVault is legitimate.
Then, when Betty needed to switch from her PHR to Spike’s PHR, she simply clicked Switch Person and then clicked on Spike.
