Russia Unveils the First COVID-19 Vaccine For Animals

While many scientists say the virus causing covid-19 initially jumped from bats to humans, perhaps through another intermediary, infections have since been reported worldwide in animals, from zoos to mink farms.

It remains unclear how easily the virus can move between animals and humans. But after repeated outbreaks among minks at farms in Denmark and elsewhere in Europe, millions of the furry animals were killed precautionarily to cut any further transmission. Scientists have been particularly worried about mutated variants of the virus developing in minks and other animals going on to infect humans.
