"In the early 1900s, other treatments were being successfully used to treat measles. In 1919 Dr. Drummond commented that cinnamon oil was an effective prophylactic against measles or that it made measles milder.  'It has been my practice, when I meet with a case of measles in a family, to prescribe a course of cinnamon for all unprotected members of the family". 'In the majority of cases the person so treated [with cinnamon] escaped the disease [measles] altogether, or else had it in very mild form'. ---- “Cinnamon as a Preventive of Measles,” American Druggist Pharmaceutical Record, New York, November 1919, p. 47.  [2013] Vaccines: a peek beneath the hood By Roman Bystrianyk and Suzanne Humphries, MD
