Dementia and the Shingles Vaccine: New Canadian Study

I confess that I am baffled by much of the assertions about shingles vaccinations.

I am not a vaccine doubter although I have some reservations about mRNA vaccine claims.

My confusion is based on comprehension of claims such as above of a 3 year follow up indicating "less risk" of conditions that apparently have not "yet" occurred when and while the possibility of same onset of conditions are increasingly being linked to combined risk inherited genetics .

I had a 82 year old neighbor who suffered shingles of one eye and she confessed that the incessant pain gave rise to thoughts of suicide. She had no recall of ever suffering from chickenpox as nor do I .

I historically have only tested positive for antibodies from Hep B which I unwittingly apparently acquired some time in my late teens which sadly denies me from donating blood.

So while I can understand that the efficacy of a vaccine against the specific pathogen it was developed for by measurable immune response how is it possible to measure efficacy in relation to dementia and/or Alzheimer's which as far as I know are not currently attributed to a pathogen? Or is this a subdued revelation ?

There is no evidence linking ANY vaccination to an increased risk of dementia. OTOH, there is quite a body of evidence vaccinations reduce the risk of dementia, by between 20% to 40%.

This is held to be due to the reduction of neuroinflammation, and training the immune system to reject toxic proteins.

Most research suggests high blood pressure and insulin resistance are factors in the development of dementia.

Extensive research indicates daily physical exercise is one of the most effective interventions for reducing the risk of cognitive decline.

    No, it was not. As per the info in The Lancet, funding came from the following organisations: https://www.thelancet.com/journals/laneur/article/PIIS1474-4422(25)00455-7/fulltext

A friend of mine here in Thailand got Shingles and strongly advised me to get the vaccine because of the pain he suffered with it. I checked with RAM hospital here in Chiang Mai, 6000baht per dose. I was heading back to Australia for a visit soon after so did some research and found as a pensioner I could get them free, which I did.

So did I

My older brother got it (64yrs old). Rash, blisters, body pain, he said it really sucked.

Next day I got shot #1. Gave me flu like symptoms, I threw up in the middle of the night.

Shot #2 four months later, no side effects. Shots covered under my work health plan.

Had 2 no one worried me

If you're writing on AN, probably not mens sana! (Including moi.)

Are there any after effects of the vaccine. As I had a cold, my pharmacy advised me to have it when better as it can make you very tired for a day or two. Im wondering as I’ll be traveling soon.

No after affects on Shingrix vaccine, but same as you I had after both my Covid vaccines. I had the first dose one month ago!

Is it necessary to get this shingles shot after the age of 70?

If you don't have the vax you should get it. A friend of mine had shingles last year. You don't want it.

Really - if you want the Shingles vaccine, then get the shingles vaccine. But I've read the research. Using relative efficacy (Relative Risk Reduction) that vaccine looks brilliant. RRR at 90%. Look at the absolute efficacy (Absolute Risk Reduction) and I'm personally not sold on it. My research indicated that ARR is as low a 3 people per 1000 who would not get shingles as compared to a placebo. ARR ranges from 0.27 to 3.3 from my own reading. If ARR was 90, I'd go out and get the vaccine tomorrow. But between 0.27 and 3.3? I just don't see the benefit. Btw. Women and people with family history of shingles are at the highest risk. I'm not a woman and no one in my family has ever had shingles. Do I trust the research on decreasing dementia. Not particularly.

I'm not trying to change anyone's mind. Informed Consent means - Do Your Own Research - obtain your own facts, make the choice that is right for you. If YOU believe that the vaccine is 90% effective AND keeps you from getting dementia - please! Go get the shot.

THe absolute risk scam has been an issue with Youtube health gurus forever.

Edit: You are also fudging the math :) You are using relative risk annually but we live more than one year :)


You don't live your life in one-year increments when it comes to a dormant virus. Since 1 in 3 people get shingles in their lifetime, the lifetime ARR is effectively $30%. If someone offered you a shot to reduce a $33% lifetime risk of agonizing nerve pain down to about $1%, you'd take it.

I've had a weird year with my health and just starting to get back on track after a bat bite 2 months ago and a few unexpected muscular issues with the rabies vaccine.

How long will the Shingles vaccine stop me from exercising? Will I be able to start back up where I was before the vaccine or is there a lag effect.

One day, maybe. You might not get the reaction I got (flu like from shot #1 for one day), otherwise a bit of shoulder pain at the injection site that might keep you from excising that shoulder. Should not really interrupt your exercise program.

Perfect, AI I find uses knowledge provided from "experts" when it comes to vaccines which can be far off from what happens to healthy people. I put on my schedule for March 2027 for the first of the two shots recommended. Did you get the second shot? The research shows that many skip that second shot which increases the odds of getting shingles substantially after a few years compared to getting two shots. If you did, I bet it was even easier. Last, question, do you plan on doing every 5-10 years?

A. you come off as a weird Forum numpty if you scheduled a shot for a year from now, when you could go tomorrow.

B. probably not

If vaccines are so effective and wonderful, then..............why Isn't There A DEMENTIA VACCINE.

biggrin "You just need to get the shingle vaccine bro'."
I just say, 'Bravo Sierra'. 🐂💩

Viagra was not ment to be for erectile dysfunction, just happened to be one of the side effects. Still there is more research that needs to be done before conclusion, but so far indications says there can be a connection.

Anyway, at closer to death than born, what is it to risk really?

you clearly aren't interested in understanding dementia.

Recent studies suggest the Shingrix shingles vaccine may reduce dementia risk by roughly 20-30% by preventing the herpes zoster virus from reactivating and causing chronic inflammation.

Many reasons for the delay. Just got over a bad rabies vaccine experience and getting back on track with my health. Thanks for answering the questions.

Hi,

Just out of interest, what was the rabies vaccine eperience?

I had a mild reaction similar to a cold, and was back into my usual exercise routine after a couple of days.

Just take some Triactin and you'll be fine.

My calves locked up even walking fast but was able to move to steep inclines(15%)on the treadmill for 40 days. Then Starting to run again after was difficult and kept getting injured. Just starting to feel normal ands that is why I'm postponing the shingles vaccine.

Neither myself nor my wife had any muscular issues after getting the shingles vaccine (slight ache in the deltoid muscle area, is all). Both of us were able to continue with our normal daily activities (including exercising and gardening, for example) without any interruption.
