Hardly any traditional childhood vaccines require boosters though.

Most vaccines carry lifelong protection as soon as the original primary/induction series is complete.

The only exceptions I can think of are influenza, tetanus and the oral ETEC travelers' diarrhea vaccine.

Influenza isn't really a traditional vaccine since it only offers partial and temporary protection.

Tetanus is boosted every ten years. Some research argues even this is unnecessary and you could probably get away with every 30.

The Dukoral ETEC oral travelers' diarrhea vaccine isn't a traditional vaccine either since it's swallowed and was originally designed to protect against cholera. Now it's marketed to westerners to reduce the risk of TD but with "shitty" efficiency of less than 25% and only lasting 3 months to 2 years.
