"Promising Alzheimer's Vaccines Advance to Clinical Trials, Building on Success of Breakthrough Treatments"
Several Alzheimer's vaccines are entering clinical trials as breakthrough treatments that remove toxic proteins from the brain have shown success in fighting the disease. Clinical trials are underway or completed for at least seven vaccines designed to harness the immune system to rid the brain of disease-related proteins. The renewed interest in Alzheimer's vaccines follows a promising first attempt more than 20 years ago that was abandoned due to safety concerns. The success of recent treatments has revived interest in vaccines as a cheaper and easier-to-administer option for millions of people. While vaccines are still in the early stages and will require large trials, they could offer a respite from expensive infusion treatments and expand access to Alzheimer's treatment globally.
