Wolfberries Enhance Protective Effect Of Flu Vaccines Among Older Mice

December 11, 2013: 12:00 AM EST
U.S. scientists have shown in a study in older mice that ingestion of wolfberries, also known as Goji berries, improves the protective effect of flu vaccines. The researchers believe the berries increase the activity of dendritic cells important to the immune system’s ability to defend against viral infections. They said the results are important because they suggest that the berries have the potential to reduce age-related risk and severity of the flu virus in the presence of the flu vaccines. Flu vaccination is recommended for older people, but the vaccine is only 40 percent  effective in protecting older adults against infection
