A successful stress-reduction program is most likely to quicken June's recovery from viral pneumonia by INCREASING her body's production of T-lymphocytes.

Explanation:

Viral pneumonia, depending on the type of virus and age of the patient, induces a cell-mediated immunity. Viral recognition by the T-Helper cells initiate the activation and production of antibodies by the B-lymphocytes. Sequentially, the activated B-cells are able to signal T-cytotoxic cells to help kill remaining viral infections.

An example of a stress-reduction program is Mindfulness-based stress reduction (MBSR), developed by Jon Kabat-Zinn. It helps in training people to develop awareness and attention to detail, so they could create more choices and decisions in life. Though with numerous studies, it has not been proven to help treat certain infectious diseases.
