    (e) A lupoid reaction or keloid is occasionally seen 1-2 years later at the local site, particularly if it has been chosen too high on the shoulder. 119 Post-Vaccination Care (a) General. For those not liable to future special risk (paras 102(a), (b) and (c)) no test for conversion to tuberculin positive is required (para 106(b)). No special post- vaccination segregation is needed. (b) Those to be at risk (1) Individuals whose future occupation or circumstances will involve definite risk of infection (paras 102(d) and (e)) will be given a test for conversion to tuberculin positive eight weeks after B.C.G, vaccination (para 106(b)). If this test is negative they will be revaccinated. (2) Until a positive tuberculin reaction has been obtained they will be kept from any known or likely source of infection (such as personal contact with cases, or duties involving contact with potentially infected material). In particular no medical, dental, nursing officer or auxiliary, laboratory technician or other individual whose normal duties involve contact with patients or tuberculous material, will be employed in wards in which tuberculous patients are being treated, or be allowed near such patients or tuberculous material, unless he or she is naturally tuberculin positive or has been rendered so artificially. 120 B.C.G. Vaccination of Children in Contact with Tuberculosis (a) Newborn infants of mothers with active or recently quiescent tuberculosis (1) A newborn infant of a mother with active or recently quiescent tuberculosis should be removed from its mother at birth. No Heaf or tuberculin test is needed, and the infant should be vaccinated with B.C.G. on the fourth or fifth day after birth. The risk of abscess formation must be accepted in these circumstances (see para 121 (1)(1). (2) The baby should remain in hospital segregated from the mother until a definite local reaction at the vaccination site has developed. When this occurs the child may be returned to the mother provided that any active disease is receiving treatment, the mother has been told how to protect the baby from infection and she remains under supervision so long as her tuberculosis is active. (3) If no local reaction develops.in eight weeks, revaccination in the other arm should be done, using a fresh batch of vaccine. Separation from the mother is continued until a local lesion develops. The child is then returned to the mother. If there is no local reaction after four weeks following the second vaccination, the child is tuberculin tested and if negative revaccinated once again. In the rare event of no lesion developing after the third vaccination the child may be returned to the mother, but kept under observation. (b) Contact between child and mother with arrested or recovered tuberculosis. The child should be tuberculin tested and if negative given B.C.G. forthwith. No special action need be taken. (c) Older children who are contacts of cases. Action required is as for infants who have been in contact with mothers or other persons with active tuberculosis.
