The present invention provides an immunogen composition and methods for using the same for the development of immunity. In one method, the immunogen composition is administered to prepare a person for a later booster administration. This immunogen composition includes an antigen and a polyoxyalkylene block copolymer. In another method the booster administration is given to a person previously prepared for the booster through prior administration of the immunogen composition. Another method includes multiple administrations, with a later administration boosting the immune response from a prior administration.
