Abstract: To solve unconstrained optimization problems，applying the properties of diversity of the population can be maintained in the immune system to avoid falling into a local optimum and the phenomenon of premature convergence to standard genetic algorithm，a new immune genetic algorithm based on vaccination is put forward.The results of the experiments show that the new algorithm has good performance to the function which has many local optimal solutions.The advantage of this algorithm is that，When the group iterative is likely to fall into local optimum，the individuals are able to jump out of local optimal solution in time through timely dynamic vaccination and ultimately achieve the global optimal solution.
