Right now, there is no recommendation to get Tdap after age 64. That may change. However, since most adults haven’t gotten a Tdap, in reality a family member getting pregnant is often when grandparents to be end up getting that one, regardless of age.
I suggest a nice Golden Retriever or Lab for whooping crane protection. Definitely not a Corgi or Chihuahua…whooping cranes get pretty big. 
It used to be every 10 years with the old vaccine up to the 1990s. The vaccines used now are not as effective and when I received my booster a few months ago I was told it was good for about 6 years.
I’m neither and I still got a booster about 5 years ago.
Here’s an interesting story about an anti-vaccer who changed her mind about vaccinations when she realized there was a measles outbreak in Ottawa. Unfortunately, her kids all caught pertussis before they could fully be immunized.
Tara Hills, Ottawa mom, changes anti-vaccination stand, but 7 kids still get sick
Here’s a video of an infant with pertussis. This is from a training video to show doctors what pertussis looks like.
Not literally. (God, I hope not, at least).
It’s an example of “literally” being used in a literally figurative sense.
Speaking of human experiments, we have recently been conducting one—an experiment on perception. Telling people that lions are dangerous is NOT the same thing as feeding one of their children to a lion. It’s also an experiment in irony—a generation of mothers who never saw any of their siblings or schoolmates die of diphtheria or polio simply do not believe that their own children are threatened by what have become, to them, imaginary diseases. A complete and total absence of Today show segments about the horrors of measles is compared in the minds of the public against weekly segments detailing the horrors of autism, and bingo, the fear of autism outweighs the fear of measles by several orders of magnitude.
On the larger scale, we see proven, among a whopping sample population, my own hypothesis (I teach reading, writing, and social research methods) to wit: “Facts” and “Logic” have ZERO effect when it comes to changing people’s minds. About ANYTHING.
Isn’t scientific research on human subjects fun?

Good for your mom!
My mom mentions my grandmother, who had polio as a child. She lived with a club foot, on a leg shorter than the other. She had several surgeries to try to help, but until her death at age 93, one leg was a few inches shorter than the other. She had terrible arthritis in the affected hip, knee, and ankle.
But polio as a child with the resulting club foot/leg shortening meant that as a girl she could no longer run with the other kids, she couldn’t play softball. She never got to dance.
And if THAT doesn’t work…mom has stories of kids she went to school with dying of complications of various childhood diseases.
(Mom was a teacher and doesn’t suffer fools very well.)
Yup. One of my former bosses is a pediatrician. He saw a child die of complications of the measles when he was doing his residency and was furious that this should happen in the late-20th century, and horrified that he couldn’t do anything. When he was in practice, he would counsel parents who were against vaccines. He’d explain how vaccines work and why they are important and what they really do and do not contain. He’d explain why the Wakefield study was so wrong and why Jenny McCarthy is a nutburger. He’d cozen them along for a bit, but at the end of it all, if they continued to refuse to comply with the standard vaccine schedule, he’d “fire” them from his practice.
