It sounds like you’d potentially want to err on the side of better safe than sorry & get the shingles vaccine, but definitely talk to you doctors about whether your other medical conditions might affect whether the vaccine is a good idea for you personally.

Dr Ellie Murray, ScD @epiellie.bsky.social · 28/08/2026
I’ll say this: I personally will be getting the shingles vaccine when I’m eligible because shingles sucks. But chickenpox also really sucked & if I could have not had that I very happily would have, even if it meant I still had to get the shingles vaccine.

Thanks, I guess it’s a matter of probabilities but maybe not so unnecessary as I thought.

Dr Ellie Murray, ScD @epiellie.bsky.social · 27/08/2026
If you had the chicken pox vaccine & have never had any symptoms, the chances of shingles are almost nill. At the moment, there’s no good evidence that the shingles vaccine does anything other than prevent shingles, so no I wouldn’t recommend it in this case. But, as always, talk to your doc!

Love this! We need more and better descriptive studies. For those whose descriptive psych studies are somewhat epidemiologic in nature, might I recommend this paper on how to do good descriptive work👇🏼 pubmed.ncbi.nlm.nih.gov/35774001/

A Framework for Descriptive Epidemiology - PubMed
In this paper, we propose a framework for thinking through the design and conduct of descriptive epidemiologic studies. A well-defined descriptive question aims to quantify and characterize some feature of the health of a population and must clearly state: 1) the target population, characterized by …

Nice explanation of why you should be skeptical of the latest shingles vaccine side benefit study. Shingles sucks big time & that alone is enough reason to get the vaccine. Would it be nice if it were also a magic cure-all? Sure. But how likely is that.

In nutrition research, the effect you estimate from a model is determined by which other dietary variables you adjust for. If you adjust for total energy intake, the effect will switch from an addition to a substitution. Which substitution will be determined by which other variables are adjusted.

Tapping the sign…
Screenshot of an old tweet of mine from 4/18/25:

Some of y'all forget the reason we have food safety regulations is because companies used to do things like adding chalk to spoiled milk so it looked normal.

Regulations don't exist because governments enjoy them. They exist because pure unadulterated capitalism would kill us.

We need to see MAHA as the product of a political economy designed to sow doubt and undermine public institutions, rather than a solution to the structural forces that have created a sense of abandonment and dislocation in too many communities and left them vulnerable to bad faith actors.

Happy 250th, USA! May we reach for the best of ourselves as we shape the next 250 I draw inspiration from this 1941 Jacob Lawrence painting celebrating new opportunities for Black children through the Great Migration Lawrence describes how policies shaped a standard of living conducive to learning
Jacob Lawrence painting and description:

With arms stretched high, these three girls reach to write numbers on a large, clean chalkboard. Their bright dresses and modern classroom suggest that these students enjoy a standard of living that allows them focus on school work. Lawrence’s picture of a childhood education in the North contrasts sharply with his depiction of underage labor in the South in panel 24, in which bare-chested children work in cotton fields under the sun.

RCTs can have major external validity problems too. Two RCTs with the exact same trial protocol in the exact same population can have *completely different* & *equally internally valid* ITT effects if their adherence patterns happen to differ.

FFRCISTGs are a very niche & basically redundant type of causal graph, which no one ever uses because there’s no use case where it makes sense. But today, I actually had a reason to recommend it.
