That is a relatively new vaccine. In the US, that’s part of what you get as a kid now (not going to fact check the current guidance cause im afraid to look), but if you’re old enough to have actually gotten chickenpox, you likely havent gotten the vaccine unless you asked for it.

In my experience in the US, it seems like Dr’s dont really keep up with recommendations once you are over 18.

Oh yeah, I didn’t think you were conflating them. I actually really like the “among 100 women” wording cause it makes it really clear.

I basically just wanted to mention a common pitfall in this type of literature if anyone wanted to dig into it based on your comments.

Not nitpicking your numbers at all (mainly cause im too lazy to go hunting down the original sources), but a big problem that science media gets completely wrong is how they report risk percentages. They conflate changes in absolute risk with relative risk constantly, and it really hurts messaging.

For example, a few years back, the WHO released a report on consumption of processed meat and how it relates to colorectal cancer risk. Even their own press release, which should be perfect, says “each 50 g portion eaten daily increases the risk by 18%”. That is really misleading if you dont know they are talking about a relative risk. The average person will interpret this as new risk %= baseline risk % + 18%.

The absolute lifetime risk of colorectal cancer is ~4%, so daily consumption of processed meat should bump it to ~4.7% (well, technically lower since the 4% includes processed meat consumers). Giving the before/after percentages helps communicate the risks way better. Even better is a risk curve showing how the risk changes as consumption increases (obviously that relies on the data being available).

Its also better to be able to contextualize so you can make well informed decisions across your life, e.g., it’s dumb to deprive yourself a joy that increases lifetime cancer risk by 0.5% while ignoring other facets of your life that increase cancer by a much larger margin.
