Just an FYI - in 2017 Merial was bought out by Boehringer Ingelheim which will continue to make the Purevax rabies (both 1 year and 3 year) and other vaccinations for pets. There is probably some lingering supply of Merial Purevax in the world but that will dwindle as they get used up or expire. You may see BI Purevax listed on your pet's rabies vaccination certificate. My cats got Merial last year but today got the BI Purevax.
