“There was a slight increase in risk of HZ in people receiving influenza vaccine in the first 1–15 days after vaccination.” That’s kind of overselling it, isn’t it? The OP study says that stroke chances are lowered for 6 months. I think many people would take that trade off.

Figure 4D in the stroke study shows how small the hazard is for younger people, and how small the difference is. The shingles study shows the shingles IRR is higher for people under 65. As another comment says "I wonder at what age flu shots provide overwhelming benefits.", that is the reason why I posted it.
