No need for adult booster tetanus or diphtheria: study
There is no evidence that adult booster vaccinations for tetanus and diphtheria are beneficial in many countries, a study shows.
US researchers compared the incidence of tetanus and diphtheria in 31 European and North American countries with or without a recommendation for adult booster vaccination, using WHO case reports from 2001-16.
Specifically, countries that vaccinate adults every 5-20 years were compared with countries that do not routinely vaccinate adults for tetanus or diphtheria.
