Russian veterinary authorities recall and destroy batch 20 of the Multican-8 vaccine for dogs after lab testing detects a live Aujeszky’s disease virus in the product. The regulator says the pathogen is typically fatal to dogs. Reports from pet owners and veterinarians describe a sudden rise in pet deaths following vaccinations, with cases reported across multiple Russian regions.

Euronews and PravdaReport both state that authorities confirm the contamination through laboratory testing and connect the deaths to the specific batch. They cite reports from at least 10 regions, including Moscow, the Moscow region, Saint Petersburg, and cities such as Yaroslavl and Kostroma. Both outlets also describe the scope of fatalities as part of a broader cluster beginning in August.

The outlets differ in emphasis on the wider response and company conduct. PravdaReport adds details about the manufacturer, Vetbiohim, which it says previously denied responsibility and referenced quality-control procedures. It also reports that the company offered settlements to pet owners in exchange for dropping claims, while noting that regulators establish a direct link between the deaths and the contaminated batch.
