Immunodeficiency Clinical Trial
Official title:
Use of UV-treated Milk Powder to Increase Vaccine Efficacy in the Elderly
Aging populations experience a decline in adaptive immune system function also known as immunosenesence. Nutritional approaches to stimulate and strengthen the immune system are needed for this growing segment of the population. A controlled, randomized, double blind pilot study was conducted using two different protein sources as nutritional supplementation to enhance vaccine response. Our objective was to examine the immune stimulating effects of dairy protein subjected to ultraviolet radiation (UV-C) radiation treatment process instead of pasteurization. Participants were 21 healthy individuals over 60 years of age who consumed 6 g of the dairy protein or a comparison, soy isoflavone protein, twice a day for eight weeks. DTaP vaccine administered at week 4. Non-parametric t-tests revealed a significant increase in Tetanus antibodies in the dairy group compared to the soy group at week 8. These findings suggest additional benefits of UV-C treated unheated dairy protein as a solution to counteract immunosenescence, but warrant further study in elderly and other populations that might benefit from immune system stimulation.
