There’s been a lot of talk on the forum about vaccines, latent infections, links between viruses and longevity recently. So this paper, published 4 days ago, is perfectly timed.
The highlights (curated and edited by me, not direct quotes):
Observational study
1,271,922 individuals, mean age 61.3, 43.2% male, median follow-up time, 6.0 years
Live zoster vaccination was associated with lower risks of overall cardiovascular events [HR 0.77, 95% confidence interval (CI) 0.76–0.78],
Major adverse cardiovascular events (MACE) [0.74 (0.71–0.77)], heart failure [0.74 (0.70–0.77)], cerebrovascular disorders [0.76 (0.74–0.78)], ischaemic heart disease [0.78 (0.76–0.80)], thrombotic disorders [0.78 (0.74–0.83)], and dysrhythmia [0.79 (0.77–0.81)].
Note, those are HUGE decreases in cardiovascular events. A 25% reduction is absolutely massive.
The protective association persisted up to 8 years, with the greatest reduction observed 2–3 years post-vaccination. The decrease in cardiovascular disease risk was more pronounced among males, individuals aged <60 years, those with unhealthy lifestyle habits, and those from low-income households and rural residents.
TO give some context, I used GPT with advanced reasoning to dig out comparative numbers of risk reductions for MACE:
Live Zoster vaccine (this paper) = 23% risk reduction
Never smoking vs smoking = 31% risk reduction
Lowering LDL-C from 160 to < 100 mg/dl = 32% risk reduction
Lowering systolic BP by 20mmHg = 34% risk reduction
Of course this is an observational study, so the real world application of the vaccine for MACE reduction may have different effectiveness. But a one-off vaccine giving at least 8 years of protection is pretty phenomenal IMO. It looks to me that the “bang for buck” of this vaccination seems extremely high. It’s especially cool that largest benefits seemed to be in the younger than 60, but the rest (unhealthy lifestyle, low income) probably doesn’t apply to this forum.
I can also say from personal experience that my wife had a shingles re-emergence in her early 40’s and it was absolutely horrible. She said it was excruciating pain. I believe @adssx has also recently mentioned that he had shingles. So perhaps avoiding that, and having some additional CVD benefits, is worthwhile?
Is anybody going to ask their doctor about this?
