Anti-vaxxerism is a term that refers to a range of anti-vaccination beliefs which include the lack of scientific evidence supporting vaccination. Many anti-vaxxers will also express concerns about the safety of vaccines. These beliefs are associated with the spread of measles, mumps, rubella, and polio in the United States. The term “anti-vaccine” is preferred by some health professionals because it is the complete opposite of the term “vaccine.”

The Anti-Vaxxer Vaccine is the first digital vaccine designed to fight the spread of anti-vaxxerism online. The Anti-Vaxxer Vaccine works by analyzing content to detect misinformation about vaccines.
