How do viruses make more copies of themselves? They do this by taking over human cells. When a virus infects a cell, it hijacks the proteinmaking machinery of the cell by releasing its own genetic code, or instructions, into the cell. Now, instead of making proteins for the body, the cell starts working for the virus, helping it replicate. The cell makes more and more virus particles that are released to go on and infect more cells.

The Vaccine Makers Project (VMP) is the classroombased 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 uptodate 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.
