Where on earth do you get the notion that no vaccine lasts longer than 7 years? Also, how does one get the power to down vote.

- agentsmith 12y agoSecond paragraph, booster shots. Also, that CDC link is not based on science. More a combination of marketing and the effects of hygiene and nutrition. Same for the immune.org link. just vote everyone else up. same effect.
- mikeash 12y agoIf you're going to declare that this stuff is "not based on science" it would be really helpful if you could provide some external information that is based on science, rather than just declaring it to be so. The existence of booster shots certainly doesn't prove that no vaccine lasts more than seven years. At best it proves that those specific vaccines don't last forever. There are plenty of vaccines where you don't get booster shots though.
