My daughter is having a little baby boy her first at age 37, my wife and I both got the Tdap at the local pharmacy, I didn’t even know what a Tdap was, it was no big deal to me after it was explained. The in-laws are not getting a Tdap and will wait three months to see the baby, but they live in Arizona and we live in Texas and it is only a 3 hour drive for us, shot is good for 10 years.
Tdap is tetanus, diptheria and pertussis (whooping cough).
The 10 yr schedule for adults is mostly tetanus, but there are subtle parts of that. Tetanus is very rare. Primary defense against it is to wash the hell out of any wounds or nail stabs or whatever. Quiet little study of nursing home residents showed any military veteran at nursing homes with wounds got no tetanus. The 10 yrs thing is likely not reqd. Vets are guaranteed to have been tetanus vaxed as young adults and that was that.
The overall thing with infants is there is a vax schedule and even RFK jr agreed with the studies that defined it. The newer vaxes maybe not so much as stats have not accumulated. Have a look at infant vaccination schedule. Lots of jabs. This is the sort of thing that can be examined in other countries, too. National health departments notoriously hold all other countries in contempt and make strictly their own evaluations of things like this.
