Aluminum key to foiling disease
Aluminum is widely used in vaccines to increase their effectiveness. It helps the body better take up antigens.
Researchers in Indiana are studying ways to increase the immune response to vaccines containing aluminum. They are modifying how aluminum interacts with antigens to stimulate disease-fighting immune response. The goal is to not only improve vaccine efficacy, but also to reduce the number of doses needed to induce a protective immune response.
The researchers are studying a number of methods with promising results. One has shown that administering vaccines through the nose can effectively reduce viruses in the lungs.
