A confluence of two things happened within 5 minutes of each other: I scratched myself on some rusty scrap metal that I found on our walk - it was in a spot that a dog could easily have cut themselves on, so I picked it up to throw it away. 5 minutes later when I got home, I saw a headline for whooping cough (Pertussis) cases going up.
Since these are the same vaccine - TDAP - it seemed like a good time to throw this reminder out there. They're typically good for 10 years, but boosters are recommended at 5 years if there is a bad/dirty wound. Since I had my last one in 2018, and this didn't even break skin, I'm planning on my next one in winter 2027/2028.
