An alpaca. I got the last one.
OK, maybe not without alpacas, but with pets.
Alpacas belong to the camel family.
Alpacas are being sheared at an Alpaca Farm in Maryland, less than an hour away from the nation's capital.
They then injected the spike protein into the alpaca, whose name is Tyson.
然后，他们将这种刺突蛋白注射到这只叫" 泰森" 身上。
But sharks are not as easy to work with as alpacas.
Hector Zarate represents 17 native Peruvian artisans whose one-of-a-kind creations include ornaments, mirrors and hand-woven alpaca clothing.
As for Tyson the alpaca, the researchers say his job is done.
The team is collecting blood samples to see whether the alpaca can develop antibodies against the spike protein.
Studies have shown that alpacas and other members of the camel family are known to produce nanobodies.
Mr Brandt sales natural and colored yarn, and other alpaca products in his store at the farm.
The shearing is also profitable for farm owner Kevin Brandt. He says there is a growing demand for alpaca wool.
Mr Brandt says he entered the Alpaca of farming business, because he and his family love the animals.
Alpacas are large animals with long, thick hair. They are related to camels and lamas.
Experts estimate there are about 300,000 alpacas in the United States.
The Farm's website says 99 percent of the 3 million alpacas in the world live in Peru, Bolivia and Chile.
Mr Brandt says fewer alpacas live in places other than South America.
The alpacas on Sugarloaf Farm are sheared to keep them cool during the hot summer months.
Some of the alpacas quietly let the owners shear them, but some of them do not like it at all.
" Alpaca are just a wonderful livestock. They're gentle. We've raised our three kids here and it's a wonderful lifestyle to have, " said Brandt.
