Abstract
The present invention relates to a vaccine derived from a bacterial or virus product that initially comprises a mixture of polymers of varying molecular weights. The vaccine contains an immunogenically effective polymer comprising T-cell-independent antigen as the effective immunizing agent. The vaccine is free of low molecular weight immunosuppressive antigen-containing polymer as a result of processing of the bacterial or virus product mixture.
