Anne,
The Seattle vaccine is a DNA vaccine. The Windber one, i think, is a peptide vaccine. If you have to be tested for HLA then i think it's a peptide vaccine. The difference, as i understood it is, is that there are a lot of peptide's on cancer cells. The peptide vaccine builds up immunity to that peptide. The DNA vaccine is suppose to be broken down one step already so the immunity should be easier to get. It's very confusing, if someone else understands it differently please respond
