INTRODUCTION
The Director -General submits this preliminary
report in compliance with resolution EB23.R16.
The operative part of the resolution reads:
REQUESTS the Director -General to present to the twenty - fourth session of the Executive Board a report on BCG vaccination programmes including the technical value of such vaccination and its place in tuberculosis control programmes, to the extent it is possible at that time, and to present a further report to the twenty -fifth session.
A considerable part of Part I of the present report
consists of a review of some of the most recent
publications, in which the results of follow -up for a sufficient length of time are given, and on which a technical appraisal of the productive value of BCG vaccination can be based. Only publications dealingwith intradermal vaccination in man have been
reviewed in the present report, as this is the only method to be considered in relation to the UNICEF/WHO assisted BCG vaccination projects. Publica- 1 See resolution EB24.R20.
tions giving evidence of the protective effect of BCG vaccination in experimental animals are mentioned only briefly, mainly in connexion with the correlation between the protective effect of BCG vaccination and the degree of post- vaccination tuberculin sensitivity.
The inconvenience to the persons vaccinated and the risks directly associated with the vaccination are described mainly on the basis of publications, and a technical appraisal in quantitative terms has been attempted.
The argument often used against BCG vaccination, that it spoils the diagnostic and epidemiological value of the tuberculin test, is discussed.
A report on the lessons which might be learned from the mass vaccination programme will be made later, based on a thorough evaluation of this pro- gramme, for which plans have been made.
In Part II of this report, statistical data are given for the UNICEF /WHO -assisted BCG projects.
20 EXECUTIVE BOARD, TWENTY -FOURTH SESSION PART I. TECHNICAL VALUE OF BCG VACCINATION 1. Degree of Protection obtained by BCG Vaccin-
ation
The question is what degree of protection BCG gives against tuberculosis and, more specifically, whether the degree of protection given by the vaccina- tion is great enough to justify its application on a mass scale as part of the tuberculosis control pro- gramme.
1.1 BCG Controlled Trials
A BCG controlled trial is a scientifically planned and conducted study, the most characteristic feature of which is that each person considered eligible for vaccination is, by a random procedure of selection, allocated to one of two groups: vaccinated or controls.
All the people included in the study are then followed for several years for the purpose of discovering the cases of tuberculosis and deaths from tuberculosis which occur, precautions being taken to ensure that the controls and the vaccinated are, in all respects, treated identically. By comparing the annual inci- dence (attack rate) and the death -rate of tuberculosis in
the two groups -controls and vaccinated -an
expression is obtained for the degree of protection acquired from the vaccination.The results
of four
such studies have been published:1.1.1 Trial in North American Indians (Aronson et al.)
This trial, which was started in 1936, included
3008 Indians aged 1 -19 years, living in four reserva-tions in the United States of America and south-
eastern Alaska. At entry to the trial, all were non- reactors to 0.005 mg of purified protein derivative (PPD), reacting with less than 5 mm to this dose.As determined by a random procedure, 1551 were vaccinated and 1457 left unvaccinated as controls.
The vaccination was given intradermally with one of thirteen lots of freshly -prepared BCG vaccine, using a dose of 0.1 or 0.15 mg.
The study population was subjected to an initial chest x -ray examination, and four persons, three vaccinated and one control, showing radiological evidence of pulmonary tuberculosis, were excluded.
No efforts were made to prevent exposure to tuber-
culosis; approximately 20 per cent., in both the
vaccinated and the control group, had contact with tuberculosis during the first six years of the study.Post -vaccination tuberculin sensitivity: 36.7 per cent. of those vaccinated were reactors to the very
low dose of 0.00002 mg of PPD at one year and
47.8 per cent. at two years. For two lots of vaccine, prepared from veal -potato medium instead ofSauton's medium, the percentage of reactors was
markedly lower -13.8 and 15.6 at one year and
28.3 and 30.5 at two years.The morbidity from tuberculosis, as judged by annual radiography, was studied for eleven years
(1936- 1947). During this period, definite pulmonary lesions -classified as primary tuberculosis, minimal to far -advanced tuberculosis, miliary tuberculosis and pleural effusion -were observed in 64 (4.1 per cent.) of those vaccinated and 238 (16.4 per cent.) of the control group. Non -tuberculous pulmonary
lesions, on the other hand, were about equally
frequent in the two groups; they occurred in 5 per cent. of the vaccinated persons and in 5.6 per cent.of the controls.
As shown below, there was no
significant waning of the protective effect of BCG vaccination.BCG -vaccinated Controls

Judging from these figures, the vaccination con- ferred substantial protection for at least fifteen years.
There is some suggestion, however, of a waning of the protective effect after ten years.
The cumulative death -rates from non -tuberculous causes are almost the same among the vaccinated and the controls, 600 and 567 per 10 000 respectively.
ANNEX 3 21
It is of interest to note that the two lots of vaccine which gave particularly low conversion rates also showed a comparatively low protective effect. These two lots were used in a single reservation -Rosebud Agency -and a comparison of the results obtained in this reservation and in the remainder of the study population is given below.

In summary, this trial provides considerable evidence that BCG vaccination, even under adverse circumstances such as poor economic conditions and considerable exposure to tuberculosis, can confer
substantial and durable
protection. Tuberculosismorbidity was reduced by about 75
per cent.over a period of eleven years and tuberculosis mortality by about 80 per cent. over a period of
fifteen years.1.1.2 Trial in Adolescent Urban Population (British Medical Research Council)
This trial deals with the effectiveness of vaccination in adolescents living in urban and suburban areas of highly -developed, industrialized communities.
The study population comprised 56 000 children of school -leaving age (14 -15 years) with a negative
radiograph and no recent contact with tuberculosis.
At entry to the trial- between 1950 and 1952 -22 300 were classified as reactors and 33 700 as non -reactors to tuberculin. This
classification was based on testing with two doses -3 and 100 TU of Old
Tuberculin. Persons with 5 mm or more of indura- tion to either test were regarded as reactors and those with reactions of less than 5 mm to both tests were regarded as non -reactors.
The non -reactors were randomly divided into
control, BCG vaccination and vole -bacillus vaccina- tion groups. The last- mentioned group will not be considered here; it can, however, be stated that its morbidity experience did not differ from that of the BCG vaccination group.The BCG vaccine was supplied by the Statens
Seruminstitut, Copenhagen. It was given by intra- dermal injection, using a dose of 0.075 mg.Representative samples of the vaccinated and
control groups were retested three to five months after vaccination. Eighty -six per cent. of the BCG- vaccinated persons reacted with 5 mm or more to 3 TU of Old Tuberculin.By June 1956, the date of the latest report, the
trial population had been followed up for an average of four years.' The follow -up has involved annual examinations, including chest radiography. In addi- tion, use has been made of the information available to the local chest clinics and the notification lists of the local medical officers of health. The final assessment of possible cases was made by an in- dependent assessor who had no knowledge of the results of the tuberculin tests and of whether vaccina-tion had been performed. The results are given
below.

22 EXECUTIVE BOARD, TWENTY- FOURTH SESSION
It is seen that the incidence of tuberculosis in
the BCG- vaccinated group is only about one -fifthof that in the concurrent control group.
Clearly,BCG vaccination has a marked protective effect
which lasts for at least four years.Whether there are any significant differences in the form or severity of the disease between the BCG- vaccinated and the controls cannot be determined as yet, the number of cases being too small.
A large part of the total cases -about 50 per cent.
during the first two and a half years and about 40 per cent. during the remainder of the observation period - occurred among the initial reactors. In the above table, the reactors have been classified into three groups according to their degree of sensitivity to tuberculin. It is seen that those with the strongest sensitivity (a reaction of 15 mm or more to 3 TU)
had by far the highest incidence of tuberculosis,
2.9 per 1000 compared with 0.8 and 0.7 in the weaker reactors and 1.9 in the unvaccinated non -reactors.In this trial, BCG vaccination has been found to be about eighty per cent. effective in adolescents, an age -group presumed to be relatively susceptible to tuberculosis. The protective effect has so far been maintained for about four years.
Also of interest is the effect of BCG vaccination on the incidence of tuberculosis in the total study population. It can be calculated that there would have been 30 cases among the non -reactors during
the first two and a half years if they had all been
vaccinated and 165 cases if none had been vaccinated.
The corresponding figures for the total study popula-
tion would have been 111 and 246 respectively.
Vaccination of all those eligible would thus have
prevented 135 cases, or 55 per cent. of the total.
Without the initial
radiographic screening which eliminated 134 cases, vaccination would have reduced the total case rate by about 35 per cent.An important point is that this trial, unlike many BCG vaccination programmes, excluded persons with low -grade sensitivity to tuberculin (those negative to 3 TU and positive to 100 TU) from the vaccinated and control groups. It is interesting to note that the follow -up of these weak reactors suggests that they possess considerable resistance to tuberculosis.
Thus, their annual incidence of tuberculosis - 0.7 per 1000 -was only about 40 per cent. of that of the unvaccinated non -reactors. It might therefore be speculated that vaccination may show a less marked effect where the study population includes a large
proportion of persons with low -grade sensitivity.
1.1.3
Trial in Puerto Rico (United States Public
Health Service)This
trial was carried out on nearly 200 000
children aged 1 -18 years.The study population
was given a two -dose series of tuberculin tests. The first dose was 1 TU (0.00002 mg) of PPD (RT 19 -21 Statens Seruminstitut, Copenhagen), and the seconddose, given to non -reactors to the first
test, was 10 TU (0.0002 mg) of PPD. Children reacting with 6 mm or more of induration to either the 1 -TU or 10 -TU test were classified as reactors; those with reactions of less than 6 mm to 10 TU were classified as non -reactors.Excluding those who refused vaccination, the non- reactors were allocated by year of birth to a vaccina- tion and a control group. The composition of the study population according to tuberculin and vaccina- tion status is shown below.

A 100 -TU test was given to those allocated to the vaccination and the control groups. About 30 per cent. in both groups were found to be positive to this test (a reaction of 6 mm or more) -an indication that there was a considerable proportion of low -grade tuberculin sensitivity in the study population.
The vaccine for the trial was supplied by the New
York State Department of Health. It was used
within three to five days after preparation, a dose of0.1 mg in 0.1 ml of diluent being injected intra-
cutaneously.
Post -vaccination tuberculin testing was limited to samples of the vaccinated group. Eighty -nine per cent. were found to have reactions of 6 mm or more to 10 TU one or two years after vaccination.
For the follow -up of the tuberculosis morbidity and mortality experience of the trial population, use was made only of established reporting systems.
Record cards for all persons participating in the trial were made out, against which all death certificates and all reports of cases of tuberculosis were regularly matched.
The results of the first six years of follow -up were as follows :
