There is no such thing as “boosting” your immune system.
You can weaken your immune system through lack of sleep, stress etc but nothing you ingest will ever boost or strengthen it. Anyone saying otherwise is either trying to rip you off or is just ignorant.
Immune-enhancing role of vitamin C and zinc and effect on clinical conditions. - PubMed - NCBI
. Supplementation of vitamin C was found to improve components of the human immune system such as antimicrobial and natural killer cell activities, lymphocyte proliferation, chemotaxis, and delayed-type hypersensitivity. Vitamin C contributes to maintaining the redox integrity of cells and thereby protects them against reactive oxygen species generated during the respiratory burst and in the inflammatory response..........These trials document that adequate intakes of vitamin C and zinc ameliorate symptoms and shorten the duration of respiratory tract infections including the common cold. Furthermore, vitamin C and zinc reduce the incidence and improve the outcome of pneumonia, malaria, and diarrhea infections, especially in children in developing countries
