AMARILLO, Texas (KFDA) - In a nut shell, herd immunity is when enough people have antibodies or immunity that a virus can be controlled or no longer spreads.
However, doctors say not enough people are getting the vaccine or have natural protection to achieve herd immunity with COVID-19.
According to doctors, one of the reasons is the threshold number could be higher than we thought.
To better understand why thresholds change, I spoke with a epidemiologist with the Texas Tech Vet School about how this has worked with animals, given that is where the term began.
A donkey with a severe sarcoid is recovering after welfare charities stepped in to get him the specialist veterinary care he needed to survive.
Skye, an eight-year-old skewbald who was living on the grounds of a distillery in Fort William in the Scottish Highlands, had a large sarcoid on his chest that needed urgent veterinary attention.
A local groom and volunteers looked after Skye and a pony he lived with, after their owner could no longer care for them. They were told by a vet that Skye would need specialist surgery and dedicated aftercare, owing to the severity of the sarcoid. A combination of all these factors meant that it was suggested the “only option” could be to put the donkey down.

Menefeeceratops sealeyi adds important information to scientists’ understanding of the evolution of ceratopsid dinosaurs, which are characterized by horns and frills, along with beaked faces. In particular, the discovery sheds light on the centrosaurine subfamily of horned dinosaurs, of which
Menefeeceratops is believed to be the oldest member. Its remains offer a clearer picture of the group’s evolutionary path before it went extinct at the end of the Cretaceous.
Steven Jasinski, who recently completed his Ph.D. in Penn’s Department of Earth and Environmental Science in the School of Arts & Sciences, and Peter Dodson of the School of Veterinary Medicine and Penn Arts & Sciences, collaborated on the work, which was led by Sebastian Dalman of the New Mexico Museum of Natural History and Science. Spencer Lucas and Asher Lichtig of the New Mexico Museum of Natural History and Science in Albuquerque were also part of the research team.
