antiserum

In the late 1800s, an effective treatment with an antiserum was developed.

“The antibodies described here are promising candidates” to replace horse antiserum, the scientists write in a paper published today in Scientific Reports.

If you had smallpox, you’ve got about 10 days to provide vaccines and antiserum. and we’ve got enough vaccine to provide for everyone in the United States.

Of those, the researchers selected 44 especially well-preserved artifacts and subjected them to antiserum testing looking for proteins, specifically proteins from animals—most specifically proteins from animals that would have been used for food.

"The other possibility I'm trying to work on is to develop an antiserum from horses – the way we do with rabies – for women we know are pregnant."
