Depends on whether you are working in mice or humans.

For mice:

Antibody assessment via ELISA. You should consider the titers, subclass titers (IgG1 and IgG2a, to indirectly measure Th1 vs Th2 responses), and antibody avidity measured by ammonium thiocyanate elution.

You should also assess T cell responses by their ability to produce effector CD8 and CD4 T cells, you can look at cytokines that play a major role in protection from malaria including IFN-gamma, IL-2, and TNF-alpha. You can also assess memory vs effector vs effector memory responses by looking at CD127 and CD62L expression levels. You can also perform tetramer staining of T cells obtained from peripheral blood samples. 

You should then perform an experimental challenge if you are studying the immunogenicity of a non-murine parasite you should look to obtain transgenic P. berghei or P. yoelii parasites expressing the non-murine antigens that you are using for vaccination. You can then identify correlates of protection based on the antibody responses from your mice. You will likely need to have two groups - one that goes for assessment of T cell responses in splenocytes by flow cytometry, and one that will be subjected to experimental challenge, but you will still be able to correlate antibody responses. However, this depends on your institution's IACUC approval.

For humans, you will be limited by the types of experiments you can perform as you will likely only be able to assess responses in the peripheral blood and maybe perform a controlled infection where treatment is provided. This depends on IRB approval. 

I suggest looking at papers by Alberto Moreno (Emory University), Adrian Hill, Katie Ewer, and Arturo Reyes-Sandoval (Oxford) for examples.
