No, vaccines do not all cease at 7 years. For those that do wear out, keep in mind that adults do not respond the same way to as children to all diseases. For example, Tetanus is bad in an adult, so we routinely take boosters for Tetanus. Adults are pretty resistant to Pertussis and don't get as bad a disease when they do get it, so it's not critical that adults get boosters for that. You comment about hygiene is entirely misinformed. Hygiene is important for Ebola and Herpes, but not for any of the diseases we get immunizations for. You write "People who choose not to use them are not a problem because if they were then every adult who hasn't had a vaccine in seven years is also a problem so the blame should be pretty thin." Again, that's entirely wrong. Adults, as I mentioned above, are not the carriers. Secondly, please go to Wikipedia and understand "herd immunity". It is the reason measles was eradicated in the US even though some religious minorities opted out, and also the reason measles is back not that anti-vacc nonsense has become popular.
