Hey everyone, ICYMI I wanted to highlight this groundbreaking #LongCOVID preprint.

Personally, I've found there may be a lot of truth to this idea:

**High anti-spike antibodies that don’t wane 6 months after infection may be a sign of viral persistence**

Amazing study showing protective effect of herpes zoster vaccination against dementia with interesting sex differences @sexdiffimmunity.bsky.social
#vaccines work! #immunosky #medsky

Nature @nature.com · Apr 2

Vaccination against shingles might also prevent dementia, such as that caused by Alzheimer’s disease, according to a study of health records from around 300,000 people in Wales.

Does shingles vaccination cut dementia risk? Large study hints at a link

Analysis of nearly 300,000 people finds an association between the shingles jab and a lower rate of dementia — but questions linger.
