Immunization Frequency

From the Wall Street Journal Health Blog:

We may be getting far more immunizations than necessary, according to findings from a study in the current issue of the New England Journal of Medicine.

Antibodies from some vaccines stay around in the blood stream for much longer than previously thought, which means that the current schedules for some vaccinations may be overkill, the WSJ reports.

Tetanus shots, for instance, could be given every 30 years instead of every 10. And we seem to be protected from measles, mumps, and rubella for life, the researchers at Oregon Health and Science University find.
