No need for adult booster tetanus or diphtheria: study
No significant difference between countries that routinely give adult boosters and those that don't
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.
