My internist follows the recommendation to have a tetanus revaccination (Td/Tdap - which includes the vaccine for whooping cough) every ten years. I hope that the whooping cough vaccine that is being given in the US hasn’t been “outraced” by mutating bacteria from overseas.
Just like with antibiotic overuse, the bugs are mutating around vaccines as well.

“In the Netherlands, as in many other western countries, pertussis vaccines have
been used extensively for more than 40 years. Therefore, it is conceivable that
vaccine-induced immunity has affected the evolution of Bordetella pertussis.
Consistent with this notion, pertussis has reemerged in the Netherlands, despite
high vaccination coverage. Further, a notable change in the population structure of B. pertussis was observed in the Netherlands subsequent to the introduction of vaccination in the 1950s. Finally, we observed antigenic divergence between clinical isolates and vaccine strains, in particular with respect to the surface-associated proteins pertactin and pertussis toxin. Adaptation may have allowed B. pertussis to remain endemic despite widespread vaccination and may have contributed to the reemergence of pertussis in the Netherlands.”
