Damm. I've had Shingrix shots. But it's obviously not working fro me.

Post 68. It's what made me resurrect the thread.

I was vaccinated for shingles last year but it was a single dose, so it must have been Zostavax. So no dementia protection.![]()

Zostavax has been given to more than 50 million people worldwide. It was introduced in the U.S. in 2006 and discontinued in 2020.Study confirms significant waning of original shingles vaccine over 10 years (Kaiser Permanente, Division of Research, Nov 8, 2023)
No, if it was last year, it wouldn't have been Zostavax:
Hasn't the UK caught up with the 2020s yet?
A national shingles immunisation programme was introduced into the routine schedule for adults aged 70 years with a phased catch up programme for 71-79 years commencing in September 2013. At the time, the programme vaccinated eligible individuals using a single dose of Zostavax®, a live, attenuated virus derived from the Oka/Merck strain of varicella zoster virus, but at a significantly higher dose than the Varivax® varicella vaccine.
The choice of age group was based on evidence of cost effectiveness of Zostavax®. This age group were considered likely to have the greatest ability to benefit from vaccination (van Hoek et al., 2009) due to:
● the burden of shingles disease within this age group (which increases with age)
● the estimated effectiveness of Zostavax® within this age group (which decreases with age) and
● the duration of protection of Zostavax®
In the first real world assessment of vaccine effectiveness of the UK vaccine programme, effectiveness waned from 69% (95% CI 65-74%) in the first year after vaccination to 45% (95% CI 29-57%) by the third year. (Walker et al 2018)
In 2019 JCVI recommended Shingrix® should replace Zostavax® in the routine programme and that it should be offered routinely to adults aged 60 years (JCVI, 2019) based on cost effectiveness modelling. The risk of shingles and its complications increase with age and is high in individuals who are immunosuppressed. It is therefore important to ensure individuals are optimally protected at the time of greatest risk.
The JCVI recommended that Shingrix should replace Zostavax® in the routine programme and that the programme should be offered at 60 years of age. The choice of age group was based on evidence that the greatest number of cases would be prevented by administering the vaccine at this age. This is being rolled out over a period of years starting with those aged 65 and 70.
Those who have been previously eligible will remain eligible until their 80th birthday. Where an individual has turned 80 years of age following their first dose of Shingrix, a second dose should be provided before the individual’s 81st birthday to complete the course.
....
Adults aged 70 to 79 years prior to 1st September 2023 will be eligible for vaccination until their 80th birthday. Those previously eligible for Zostavax® will be offered Zostavax® whilst supplies remain. Zostavax® is given as a single dose course.
Public Health Message;
If you develop shingles seek medical attention urgently, especially if the rash affects your face or genitals. There are effective treatments that speed recovery and reduce the risk of persisting pain, but they only work if started early. As mentioned developing shingles may be the first sign of a weakened immune system and your doctor may wish to further assess for this.
You should avoid contact with unvaccinated children, pregnant women and those with weakened immune systems whilst the rash persists.

Woohoo. I had my second Shingrix vaccination last week (as far as I can remember).
Shingrix® PDF is the vaccine for shingles that is approved by Health Canada and used in Ontario. This vaccine is free through primary health care providers for seniors ages 65 to 70 years old who have not previously received a shingles vaccine. Shingrix® is given as a series of two doses, two to six months apart.
You know that you're supposed to have two shots, don't you?
She may actually have been the one who infected those children and not the other way round:

Since this is a study of the old and less effective shingles vaccine Zostavax, there is reason to assume that Shingrix will protect even better against dementia, but they still don't know exactly how the vaccine causes this effect, so only time will tell.Study finds strongest evidence yet that shingles vaccine helps cut dementia risk (TheGuardian, April 2, 2025)
Older adults in Wales who had the jab were 20% less likely to be diagnosed with dementia that those not vaccinated
(...)
Pascal Geldsetzer, at Stanford University, said: “For the first time we are able to say much more confidently that the shingles vaccine causes a reduction in dementia risk. If this truly is a causal effect, we have a finding that’s of tremendous importance.”
The researchers took advantage of a vaccination rollout that took place in Wales more than a decade ago. Public health policy dictated that from 1 September 2013, people born on or after 2 September 1933 became eligible for the Zostavax shot, while those who were older missed out.
Thanks for that.New study confirms the old ones:

By the way, it works better in women than in men, so congratulations, girls!
