Any person attending a continuing vocational training course under the terms of this Book shall be compulsorily affiliated to a social security scheme.
Trainees who were covered by a social security scheme in any capacity whatsoever prior to their training period remain affiliated to that scheme for the duration of their training period.
Trainees who were not covered by any scheme are affiliated to the general social security scheme.
However, exceptions may, by decree, be made to the rule laid down in the second and third paragraphs when the training course followed prepares exclusively and directly for a profession covered by a more favourable social security scheme than the general scheme.
