Vaccines Help Older Adults More Than We Know
Vaccines are good at preventing illness, or in the case of flu shots, keeping symptoms mild, especially in older people. The shingles vaccine, though painful (ask how we know), provides 90% protection against one of the most horrifyingly painful conditions (again, ask how we know).
Well researchers are now finding that
vaccines have several off-target benefits in older adults, including improving immune systems and lowering risk of cardiovascular hospitalization. It could also decrease the chances of dementia and Alzheimer's.
Speaking of Alzheimer's...
New research is showing that "Superagers," those over 80 with memory capacity of younger folks, may have more gene variants that protect them from developing Alzheimer's. Meaning, they have more APOE2 alleles, and fewer APOE4 alleles, which carry a greater risk of developing dementia or Alzheimer's. It's all early research, though anything we learn about Alzheimer's is a step in the right direction.
