It must be the giardia vaccine and I would not be happy it was given...
Vaccine?
A Giardia vaccine made by Fort Dodge Animal Health is on the market but it is not intended to prevent infection in the vaccinated animal. Instead the vaccine is licensed as an adjunct to treatment and is used to reduce the shedding of cysts by the vaccinated patient. This would be helpful in a kennel situation that is trying to reduce environmental contamination during an outbreak or where an animal keeps getting reinfected, but it is not helpful to the average dog whose owner wants to simply prevent infection.
The 2006 American Animal Hospital Association Guidelines list this vaccine as “not recommended.”
