Infantile Hodgkin's disease: remission after measles. 1973, Mota, BMJ

A similar case in Portugal: A two-year-old boy showed Hodgkin's lymphoma (lymphogranulomatosis). Before the radiotherapy was started, the boy contracted measles and the lymphoma disappeared. After 6 months of remission, the mother discovered reddening of the face and neck in the child, after It turned out that there was a slight relapse of the lymphoma.
Why did the mother give a two-year-old child a drink of wine, did she do it long ago, and whether this had to do with the original disease, is not reported in the article.
