Cat and dog Covid vaccine given to orangutan at San Diego Zoo

This is a quick note to record the fact that San Diego Zoo has vaccinated 9 apes, one of them an orangutan named Karen, against Covid-19. The connection to cats is that the vaccine was developed by Zoetis with cats and dogs in mind.

The reason for the vaccinations? Their lowland gorillas caught the virus. There is a discussion about the potential for animals to form a reservoir for the virus. This is the first time non-human primates have been vaccinated for this virus.

All nine apes have had both doses. No adverse side-affects have been noted. A 49-year-old silverback gorilla got the virus last month and suffered from pneumonia. He's recovering after receiving experimental antibody treatment. Eight other gorillas are also recovering after falling ill.

Karen is a Sumatran orangutan born at the zoo on 27 August 1994. She is the first orangutan to have open heart surgery.
