Immunisation of adults during an outbreak of diphtheria.
نویسندگان
چکیده
In an outbreak of infection due to Corynebacterium diphtheriae in a hospital for mentally subnormal adults sera from 211 members of staff were screened for diphtheria antitoxin titres. Of these, 79 (37%) required immunisation, and a low dose preparation (1 LfU of diphtheria and 10 LfU tetanus toxoids) was offered. Of the 64 subjects who accepted a single immunisation and were subsequently retested, seroconversion to diphtheria toxoid occurred in 45 (70%), the rate being highest in younger adults. Seroconversion to tetanus toxoid occurred in 59% of subjects. Local reactions to the single dose were reported by 29 (43%) subjects, and nine (13%) experienced moderately severe local reactions and systemic symptoms. We conclude that adults should not be vaccinated without previous screening for susceptibility to diphtheria; that neither previous immunisation nor age is reliable in predicting the need for vaccination; and that though a single booster dose of diphtheria toxoid is probably effective in adults under 45, two doses should be given to those in the older age group.

Toxigenic as well as non-toxigenic strains of Corynebacterium diphtheriae remain endemic in parts of Australia 2. The most important lesson to be learnt from recent outbreaks in the former Soviet Union, is that diphtheria recurs when community susceptibility increases and toxigenic organisms recirculate. In Australia many adults will now be susceptible, even if previously immunised, because of ...
