9 great apes at San Diego Zoo get Covid jabs
Nine great apes at the San Diego Zoo in the United States – four orangutans and five bonobos – made veterinary history in recent weeks as the world’s first non-human primates known to be vaccinated against COVID-19, zoo officials said on Thursday.
One of the recipients was a 28-year-old female Sumatran orangutan named Karen who had garnered headlines at the zoo when she became the first ape to undergo open-heart surgery in 1994. The gorillas were not vaccinated because veterinarians assumed their immune systems had already developed antibodies to the virus. They were thought to have caught the illness from an asymptomatic staff member.
Easiest to inoculate
The orangutans and bonobos selected for immunization were among the great apes at the zoo considered the most at risk of catching the virus and among the easiest to inoculate. Staff vaccinated the animals by distracting them from the needle with treats. Zoo staff began administering the shots to some of the animals in January and continued through February, with the last few given in March, Davis said.
Cross-species use of vaccines is not uncommon and apes at the zoo get human flu and measles vaccines, according to Nadine Lamberski, the chief conservation and wildlife officer for the San Diego Wildlife Alliance, the entity that owns the zoo and safari park. She said the nine great apes were the first non-human primates known to have received a COVID-19 vaccine of any kind.
“This isn’t the norm. In my career, I haven’t had access to an experimental vaccine this early in the process and haven’t had such an overwhelming desire to want to use one,” Lamberski told the National Geographic magazine in a separate interview.
