| abstract |
Vaccines comprising an immunogen and, as an adjuvant, LFA-3 or a fragment of LFA-3 capable of binding to CD2, a surface receptor on T-lymphocytes, are disclosed. LFA-3 has been found to markedly enhance the proliferation of activated T-cells and thus is capable of augmenting the immune response. Methods of vaccination in which LFA-3 is employed in conjunction with an immunogenic inoculum are also disclosed. |
