According to foreign media reports, the United States has vaccinated nine non-human primates against crown disease, which is the first time in the history of veterinary medicine in the world.
On March 4 local time, the San Diego Zoo in California announced that four orangutans and five chimpanzees in the zoo had been vaccinated.
According to zoo officials, each of the nine monkeys received two doses of the experimental vaccine designed for cats and dogs, and said they were in good condition without any adverse reactions.
In January this year, eight gorillas at San Diego wildlife park were infected with the new coronavirus, the first known case of primate infection. San Diego Zoo is worried that its animals will also be infected, so it decided to vaccinate them.
