Tetanus protection lasts 30 years: study

The protection from a tetanus vaccination may last for more than 30 years, US researchers have found.

In a challenge to the accepted view that boosters may be needed every 10 years, researchers at the Oregon Health and Science University found that the antibody titres against tetanus remained high for more than 30 years after childhood immunisation.
