The San Diego Zoo has vaccinated nine great apes for the coronavirus after a troop of gorillas in its Safari Park became infected.
Officials said Thursday four orangutans and five bonobos received COVID-19 injections in January and February.
Three bonobos and a gorilla also are expected to receive the vaccine, which is experimental.
The vaccinations followed a January outbreak of COVID-19 at the zoo’s Safari Park. Eight western lowland gorillas got the virus, probably by exposure to a zookeeper who tested positive for COVID-19.
The gorillas had symptoms ranging from runny noses to coughing and lethargy. But they are recovering.
