Neela, an Asiatic lion, died on 3 June at a zoo in Chennai after showing Covid symptoms. Eight other lions also tested positive; they have been quarantined, given antibiotics, and are under observation by veterinary teams. There have been other coronavirus cases reported in animals, including two white tiger cubs dying in Pakistan and lions testing positive in Spain. Many countries have reported infections in farmed mink. There is also evidence that mink have passed the virus back to humans in a mutated form. Meanwhile Russia has started vaccinating animals against coronavirus after registering the world's first animal-specific jab in March. Several regions have now started vaccinations at veterinary clinics. Interest has been shown in the Carnivak-Cov vaccine by the EU, Argentina, South Korea and Japan. Another vaccine is being developed by a US pharmaceutical company.
