Alzheimer’s vaccines get a boost from new drug approval

The drug’s approval has rekindled interest in other therapeutic approaches that aim to prevent or slow down the progression of Alzheimer’s, such as vaccines that stimulate the immune system to attack amyloid or tau, another protein that accumulates in the brains of people with the disease. 

Several vaccine candidates are currently in various stages of development and testing, and some researchers are optimistic that they could offer a more effective and convenient way to treat Alzheimer’s than infusions of antibodies.
