Hepatitis B virus tricks the immune system in a way that is unique compared with other pathogens. It does this by creating extra viral surface proteins during replication of whole virus particles. Although these additional surface proteins do not cause disease, they flood the bloodstream, acting as decoys. When our immune system creates antibodies to stop the infection, many of the antibodies bind to the extra proteins rather than binding to the whole virus particles. The whole hepatitis B virus particles can then go on to infect more liver cells.

Dr. Maurice Hilleman was the first to realize that these extra viral surface proteins could be used against the virus. Watch a clip from the documentary, “HILLEMAN: A Perilous Quest to Save the World’s Children,” to learn more: [ Ссылка ].

The Vaccine Makers Project (VMP) is the classroom-based program of the Vaccine Education Center at the Children’s Hospital of Philadelphia (VEC at CHOP). The Center’s team is composed of scientists, physicians, mothers and fathers devoted to the study and prevention of infectious diseases. The Center was launched in October 2000 to provide accurate, comprehensive and up-to-date information about vaccines and the diseases they prevent. The VMP program is committed to public education about vaccine science via scientifically supported, historically accurate, and emotionally compelling content.
