Shingles

The shingles vaccine is up to 97% effective in preventing the condition caused by the herpes zoster virus, which inflames nerves and causes painful rashes. Now, a new metastudy says it may also be a big help in boosting cardiovascular health.

Taking advantage of a unique public health policy in the UK, a new study has found that receiving the shingles vaccine reduces dementia risk by 20%. The findings bolster growing evidence linking the vaccine to lower numbers of dementia cases.
