Diphtheria prophylaxis with alum precipitated toxoid

Abstract

(1) Active immunisation is the best prophylactic measure we possess against diphtheria as the isolation of cases and carriers has proved a failure in preventing the spread of the disease.

(2) The success of the various prophylactics depends on the basal immunity of the child population (especially A.P.T.).

(3) T.A.F. is widely used in both children and adults. F.T. and A.P.T. should be confined to children.

(4) It is unwise to employ 'one shot immunisation' with A.P.T. except in closed communities of high basal immunity.

(5) The 'detector' dose method of using A.P.T. seems likely to give as good results as T.A.F. and perhaps may be an even better prophylactic in combating 'gravis' diphtheria.

(6) The best time to immunise is as soon as possible after a child's first birthday.

(7) Reactions are not likely to occur if the child is immunised before going to school.

(8) The pre-school child should receive almost as much attention as the school child.

(9) The general public should be educated to receive diphtheria immunisation as a natural event in a child's life.

(10) When an epidemic occurs it is too late to immunise.
