It's not on VRBO; your decision lies with the property owner.
This is information from VRBO in respects to property owners:

Contained within is: "If a traveler reaches out to cancel or delay travel, we strongly encourage you to offer a full refund due to the uncertainty of this evolving situation. When you do, we will also refund our Traveler Service Fee in full."
This is information from VRBO in respects to travelers:
https://help.vrbo.com/articles/What-can-I-do-if-my-reservation-is-affected-by-the-Coronavirus
Contained within is: "If you need to cancel an upcoming reservation due to travel restrictions, you can do so within your traveler account.
If you are making changes outside the cancellation policy window, please contact the property owner or manager to discuss their cancellation and refund policies." Additionally: "If you booked through a credit card, contact your financial institution to see if travel insurance is provided."
Have you contacted the owner of the property? Keep in mind you as the traveler aren't the only one impacted by this, the property owner is as well. BOTH are being impacted. The property owner may be out their money (and could be unable to pay their fees associated with the property) and future bookings are more than likely going to be impacted too. The reason for the cancelation is obviously valid and understandable but it also does put property owners in a very big bind just as much as the travelers. No one gets to win here.
Everyone I'm sure is really trying their best
