Q:

Is there a vaccine to prevent Alzheimer’s disease?

A:

Vaccines are currently being tested in clinical trials. There are no vaccines currently available on prescription to prevent or treat Alzheimer’s disease.

Q:

How do the vaccines being tested work?

A:

In Alzheimer’s abnormal amyloid proteins accumulate in the brain and damage nerve cells involved in the memory function.  The vaccines aim to either prevent the accumulation or facilitate the removal of the toxic amyloid proteins.

Q:

How are the vaccines administered?

A:

The current Alzheimer’s vaccines are given as either a subcutaneous injection (an injection under the skin) or an intravenous infusion (injection into a vein).  The vaccines are usually given every 2-4 weeks over a period of 18-24 months or longer.
